| 886 | =head1 NAME | |||
| 887 | ||||
| 888 | Moose::Util::TypeConstraints - Type constraint system for Moose | |||
| 889 | ||||
| 890 | =head1 SYNOPSIS | |||
| 891 | ||||
| 892 | use Moose::Util::TypeConstraints; | |||
| 893 | ||||
| 894 | subtype 'Natural' | |||
| 895 | => as 'Int' | |||
| 896 | => where { $_ > 0 }; | |||
| 897 | ||||
| 898 | subtype 'NaturalLessThanTen' | |||
| 899 | => as 'Natural' | |||
| 900 | => where { $_ < 10 } | |||
| 901 | => message { "This number ($_) is not less than ten!" }; | |||
| 902 | ||||
| 903 | coerce 'Num' | |||
| 904 | => from 'Str' | |||
| 905 | => via { 0+$_ }; | |||

| 908 | ||||
| 909 | no Moose::Util::TypeConstraints; | |||
| 910 | ||||
| 911 | =head1 DESCRIPTION | |||
| 912 | ||||
| 913 | This module provides Moose with the ability to create custom type | |||
| 914 | constraints to be used in attribute definition. | |||
| 915 | ||||
| 916 | =head2 Important Caveat | |||
| 917 | ||||
| 918 | This is B<NOT> a type system for Perl 5. These are type constraints, | |||
| 919 | and they are not used by Moose unless you tell it to. No type | |||
| 920 | inference is performed, expressions are not typed, etc. etc. etc. | |||
| 921 | ||||
| 922 | A type constraint is at heart a small "check if a value is valid" | |||
| 923 | function. A constraint can be associated with an attribute. This | |||
| 924 | simplifies parameter validation, and makes your code clearer to read, | |||
| 925 | because you can refer to constraints by name. | |||
| 926 | ||||
| 927 | =head2 Slightly Less Important Caveat | |||
| 928 | ||||
| 929 | It is B<always> a good idea to quote your type names. | |||
| 930 | ||||
| 931 | This prevents Perl from trying to execute the call as an indirect | |||
| 932 | object call. This can be an issue when you have a subtype with the | |||
| 933 | same name as a valid class. | |||
| 934 | ||||
| 935 | For instance: | |||
| 936 | ||||
| 937 | subtype DateTime => as Object => where { $_->isa('DateTime') }; | |||
| 938 | ||||
| 939 | will I<just work>, while this: | |||
| 940 | ||||
| 941 | use DateTime; | |||
| 942 | subtype DateTime => as Object => where { $_->isa('DateTime') }; | |||
| 943 | ||||
| 944 | will fail silently and cause many headaches. The simple way to solve | |||
| 945 | this, as well as future proof your subtypes from classes which have | |||
| 946 | yet to have been created, is to quote the type name: | |||
| 947 | ||||
| 948 | use DateTime; | |||
| 949 | subtype 'DateTime' => as 'Object' => where { $_->isa('DateTime') }; | |||
| 950 | ||||
| 951 | =head2 Default Type Constraints | |||
| 952 | ||||
| 953 | This module also provides a simple hierarchy for Perl 5 types, here is | |||
| 954 | that hierarchy represented visually. | |||
| 955 | ||||
| 956 | Any | |||
| 957 | Item | |||
| 958 | Bool | |||
| 959 | Maybe[`a] | |||
| 960 | Undef | |||
| 961 | Defined | |||
| 962 | Value | |||
| 963 | Str | |||
| 964 | Num | |||
| 965 | Int | |||
| 966 | ClassName | |||
| 967 | RoleName | |||
| 968 | Ref | |||
| 969 | ScalarRef[`a] | |||
| 970 | ArrayRef[`a] | |||
| 971 | HashRef[`a] | |||
| 972 | CodeRef | |||
| 973 | RegexpRef | |||
| 974 | GlobRef | |||
| 975 | FileHandle | |||
| 976 | Object | |||
| 977 | ||||
| 978 | B<NOTE:> Any type followed by a type parameter C<[`a]> can be | |||
| 979 | parameterized, this means you can say: | |||
| 980 | ||||
| 981 | ArrayRef[Int] # an array of integers | |||
| 982 | HashRef[CodeRef] # a hash of str to CODE ref mappings | |||
| 983 | ScalarRef[Int] # a reference to an integer | |||
| 984 | Maybe[Str] # value may be a string, may be undefined | |||
| 985 | ||||
| 986 | If Moose finds a name in brackets that it does not recognize as an | |||
| 987 | existing type, it assumes that this is a class name, for example | |||
| 988 | C<ArrayRef[DateTime]>. | |||
| 989 | ||||
| 990 | B<NOTE:> Unless you parameterize a type, then it is invalid to include | |||
| 991 | the square brackets. I.e. C<ArrayRef[]> will be treated as a new type | |||
| 992 | name, I<not> as a parameterization of C<ArrayRef>. | |||
| 993 | ||||
| 994 | B<NOTE:> The C<Undef> type constraint for the most part works | |||
| 995 | correctly now, but edge cases may still exist, please use it | |||
| 996 | sparingly. | |||
| 997 | ||||
| 998 | B<NOTE:> The C<ClassName> type constraint does a complex package | |||
| 999 | existence check. This means that your class B<must> be loaded for this | |||
| 1000 | type constraint to pass. | |||
| 1001 | ||||
| 1002 | B<NOTE:> The C<RoleName> constraint checks a string is a I<package | |||
| 1003 | name> which is a role, like C<'MyApp::Role::Comparable'>. | |||
| 1004 | ||||
| 1005 | =head2 Type Constraint Naming | |||
| 1006 | ||||
| 1007 | Type name declared via this module can only contain alphanumeric | |||
| 1008 | characters, colons (:), and periods (.). | |||
| 1009 | ||||
| 1010 | Since the types created by this module are global, it is suggested | |||
| 1011 | that you namespace your types just as you would namespace your | |||
| 1012 | modules. So instead of creating a I<Color> type for your | |||
| 1013 | B<My::Graphics> module, you would call the type | |||
| 1014 | I<My::Graphics::Types::Color> instead. | |||
| 1015 | ||||
| 1016 | =head2 Use with Other Constraint Modules | |||
| 1017 | ||||
| 1018 | This module can play nicely with other constraint modules with some | |||
| 1019 | slight tweaking. The C<where> clause in types is expected to be a | |||
| 1020 | C<CODE> reference which checks it's first argument and returns a | |||
| 1021 | boolean. Since most constraint modules work in a similar way, it | |||
| 1022 | should be simple to adapt them to work with Moose. | |||
| 1023 | ||||
| 1024 | For instance, this is how you could use it with | |||
| 1025 | L<Declare::Constraints::Simple> to declare a completely new type. | |||
| 1026 | ||||
| 1027 | type 'HashOfArrayOfObjects', | |||
| 1028 | { | |||
| 1029 | where => IsHashRef( | |||
| 1030 | -keys => HasLength, | |||
| 1031 | -values => IsArrayRef(IsObject) | |||
| 1032 | ) | |||
| 1033 | }; | |||
| 1034 | ||||
| 1035 | For more examples see the F<t/200_examples/004_example_w_DCS.t> test | |||
| 1036 | file. | |||
| 1037 | ||||
| 1038 | Here is an example of using L<Test::Deep> and it's non-test | |||
| 1039 | related C<eq_deeply> function. | |||
| 1040 | ||||
| 1041 | type 'ArrayOfHashOfBarsAndRandomNumbers' | |||
| 1042 | => where { | |||
| 1043 | eq_deeply($_, | |||
| 1044 | array_each(subhashof({ | |||
| 1045 | bar => isa('Bar'), | |||
| 1046 | random_number => ignore() | |||
| 1047 | }))) | |||
| 1048 | }; | |||
| 1049 | ||||
| 1050 | For a complete example see the | |||
| 1051 | F<t/200_examples/005_example_w_TestDeep.t> test file. | |||
| 1052 | ||||
| 1053 | =head1 FUNCTIONS | |||
| 1054 | ||||
| 1055 | =head2 Type Constraint Constructors | |||
| 1056 | ||||
| 1057 | The following functions are used to create type constraints. They | |||
| 1058 | will also register the type constraints your create in a global | |||
| 1059 | registry that is used to look types up by name. | |||
| 1060 | ||||
| 1061 | See the L</SYNOPSIS> for an example of how to use these. | |||
| 1062 | ||||
| 1063 | =over 4 | |||
| 1064 | ||||
| 1065 | =item B<< subtype 'Name' => as 'Parent' => where { } ... >> | |||
| 1066 | ||||
| 1067 | This creates a named subtype. | |||
| 1068 | ||||
| 1069 | If you provide a parent that Moose does not recognize, it will | |||
| 1070 | automatically create a new class type constraint for this name. | |||
| 1071 | ||||
| 1072 | When creating a named type, the C<subtype> function should either be | |||
| 1073 | called with the sugar helpers (C<where>, C<message>, etc), or with a | |||
| 1074 | name and a hashref of parameters: | |||
| 1075 | ||||
| 1076 | subtype( 'Foo', { where => ..., message => ... } ); | |||
| 1077 | ||||
| 1078 | The valid hashref keys are C<as> (the parent), C<where>, C<message>, | |||
| 1079 | and C<optimize_as>. | |||
| 1080 | ||||
| 1081 | =item B<< subtype as 'Parent' => where { } ... >> | |||
| 1082 | ||||
| 1083 | This creates an unnamed subtype and will return the type | |||
| 1084 | constraint meta-object, which will be an instance of | |||
| 1085 | L<Moose::Meta::TypeConstraint>. | |||
| 1086 | ||||
| 1087 | When creating an anonymous type, the C<subtype> function should either | |||
| 1088 | be called with the sugar helpers (C<where>, C<message>, etc), or with | |||
| 1089 | just a hashref of parameters: | |||
| 1090 | ||||
| 1091 | subtype( { where => ..., message => ... } ); | |||
| 1092 | ||||
| 1093 | =item B<class_type ($class, ?$options)> | |||
| 1094 | ||||
| 1095 | Creates a new subtype of C<Object> with the name C<$class> and the | |||
| 1096 | metaclass L<Moose::Meta::TypeConstraint::Class>. | |||
| 1097 | ||||
| 1098 | =item B<role_type ($role, ?$options)> | |||
| 1099 | ||||
| 1100 | Creates a C<Role> type constraint with the name C<$role> and the | |||
| 1101 | metaclass L<Moose::Meta::TypeConstraint::Role>. | |||
| 1102 | ||||
| 1103 | =item B<maybe_type ($type)> | |||
| 1104 | ||||
| 1105 | Creates a type constraint for either C<undef> or something of the | |||
| 1106 | given type. | |||
| 1107 | ||||
| 1108 | =item B<duck_type ($name, \@methods)> | |||
| 1109 | ||||
| 1110 | This will create a subtype of Object and test to make sure the value | |||
| 1111 | C<can()> do the methods in C<\@methods>. | |||
| 1112 | ||||
| 1113 | This is intended as an easy way to accept non-Moose objects that | |||
| 1114 | provide a certain interface. If you're using Moose classes, we | |||
| 1115 | recommend that you use a C<requires>-only Role instead. | |||
| 1116 | ||||
| 1117 | =item B<duck_type (\@methods)> | |||
| 1118 | ||||
| 1119 | If passed an ARRAY reference as the only parameter instead of the | |||
| 1120 | C<$name>, C<\@methods> pair, this will create an unnamed duck type. | |||
| 1121 | This can be used in an attribute definition like so: | |||
| 1122 | ||||
| 1123 | has 'cache' => ( | |||
| 1124 | is => 'ro', | |||
| 1125 | isa => duck_type( [qw( get_set )] ), | |||
| 1126 | ); | |||
| 1127 | ||||
| 1128 | =item B<enum ($name, \@values)> | |||
| 1129 | ||||
| 1130 | This will create a basic subtype for a given set of strings. | |||
| 1131 | The resulting constraint will be a subtype of C<Str> and | |||
| 1132 | will match any of the items in C<\@values>. It is case sensitive. | |||
| 1133 | See the L</SYNOPSIS> for a simple example. | |||
| 1134 | ||||
| 1135 | B<NOTE:> This is not a true proper enum type, it is simply | |||
| 1136 | a convenient constraint builder. | |||
| 1137 | ||||
| 1138 | =item B<enum (\@values)> | |||
| 1139 | ||||
| 1140 | If passed an ARRAY reference as the only parameter instead of the | |||
| 1141 | C<$name>, C<\@values> pair, this will create an unnamed enum. This | |||
| 1142 | can then be used in an attribute definition like so: | |||
| 1143 | ||||
| 1144 | has 'sort_order' => ( | |||
| 1145 | is => 'ro', | |||
| 1146 | isa => enum([qw[ ascending descending ]]), | |||
| 1147 | ); | |||
| 1148 | ||||
| 1149 | =item B<as 'Parent'> | |||
| 1150 | ||||
| 1151 | This is just sugar for the type constraint construction syntax. | |||
| 1152 | ||||
| 1153 | It takes a single argument, which is the name of a parent type. | |||
| 1154 | ||||
| 1155 | =item B<where { ... }> | |||
| 1156 | ||||
| 1157 | This is just sugar for the type constraint construction syntax. | |||
| 1158 | ||||
| 1159 | It takes a subroutine reference as an argument. When the type | |||
| 1160 | constraint is tested, the reference is run with the value to be tested | |||
| 1161 | in C<$_>. This reference should return true or false to indicate | |||
| 1162 | whether or not the constraint check passed. | |||
| 1163 | ||||
| 1164 | =item B<message { ... }> | |||
| 1165 | ||||
| 1166 | This is just sugar for the type constraint construction syntax. | |||
| 1167 | ||||
| 1168 | It takes a subroutine reference as an argument. When the type | |||
| 1169 | constraint fails, then the code block is run with the value provided | |||
| 1170 | in C<$_>. This reference should return a string, which will be used in | |||
| 1171 | the text of the exception thrown. | |||
| 1172 | ||||
| 1173 | =item B<optimize_as { ... }> | |||
| 1174 | ||||
| 1175 | This can be used to define a "hand optimized" version of your | |||
| 1176 | type constraint which can be used to avoid traversing a subtype | |||
| 1177 | constraint hierarchy. | |||
| 1178 | ||||
| 1179 | B<NOTE:> You should only use this if you know what you are doing, | |||
| 1180 | all the built in types use this, so your subtypes (assuming they | |||
| 1181 | are shallow) will not likely need to use this. | |||
| 1182 | ||||
| 1183 | =item B<< type 'Name' => where { } ... >> | |||
| 1184 | ||||
| 1185 | This creates a base type, which has no parent. | |||
| 1186 | ||||
| 1187 | The C<type> function should either be called with the sugar helpers | |||
| 1188 | (C<where>, C<message>, etc), or with a name and a hashref of | |||
| 1189 | parameters: | |||
| 1190 | ||||
| 1191 | type( 'Foo', { where => ..., message => ... } ); | |||
| 1192 | ||||
| 1193 | The valid hashref keys are C<where>, C<message>, and C<optimize_as>. | |||
| 1194 | ||||

| 1199 | =over 4 | |||
| 1200 | ||||
| 1201 | =item B<< match_on_type $value => ( $type => \&action, ... ?\&default ) >> | |||
| 1202 | ||||
| 1203 | This is a utility function for doing simple type based dispatching similar to | |||
| 1204 | match/case in OCaml and case/of in Haskell. It is not as featureful as those | |||
| 1205 | languages, nor does not it support any kind of automatic destructuring | |||
| 1206 | bind. Here is a simple Perl pretty printer dispatching over the core Moose | |||
| 1207 | types. | |||

| 1217 | sort keys %$hash | |||
| 1218 | ) . ' }'; | |||
| 1219 | }, | |||
| 1220 | ArrayRef => sub { | |||
| 1221 | my $array = shift; | |||
| 1222 | '[ ' . ( join ", " => map { ppprint($_) } @$array ) . ' ]'; | |||
| 1223 | }, | |||
| 1224 | CodeRef => sub {'sub { ... }'}, | |||
| 1225 | RegexpRef => sub { 'qr/' . $_ . '/' }, | |||
| 1226 | GlobRef => sub { '*' . B::svref_2object($_)->NAME }, | |||
| 1227 | Object => sub { $_->can('to_string') ? $_->to_string : $_ }, | |||
| 1228 | ScalarRef => sub { '\\' . ppprint( ${$_} ) }, | |||
| 1229 | Num => sub {$_}, | |||
| 1230 | Str => sub { '"' . $_ . '"' }, | |||
| 1231 | Undef => sub {'undef'}, | |||
| 1232 | => sub { die "I don't know what $_ is" } | |||
| 1233 | ); | |||
| 1234 | } | |||
| 1235 | ||||
| 1236 | Or a simple JSON serializer: | |||
| 1237 | ||||
| 1238 | sub to_json { | |||
| 1239 | my $x = shift; | |||
| 1240 | match_on_type $x => ( | |||
| 1241 | HashRef => sub { | |||
| 1242 | my $hash = shift; | |||
| 1243 | '{ ' | |||
| 1244 | . ( | |||
| 1245 | join ", " => | |||
| 1246 | map { '"' . $_ . '" : ' . to_json( $hash->{$_} ) } | |||
| 1247 | sort keys %$hash | |||
| 1248 | ) . ' }'; | |||
| 1249 | }, | |||
| 1250 | ArrayRef => sub { | |||
| 1251 | my $array = shift; | |||
| 1252 | '[ ' . ( join ", " => map { to_json($_) } @$array ) . ' ]'; | |||
| 1253 | }, | |||
| 1254 | Num => sub {$_}, | |||
| 1255 | Str => sub { '"' . $_ . '"' }, | |||
| 1256 | Undef => sub {'null'}, | |||
| 1257 | => sub { die "$_ is not acceptable json type" } | |||
| 1258 | ); | |||
| 1259 | } | |||
| 1260 | ||||
| 1261 | The matcher is done by mapping a C<$type> to an C<\&action>. The C<$type> can | |||
| 1262 | be either a string type or a L<Moose::Meta::TypeConstraint> object, and | |||
| 1263 | C<\&action> is a subroutine reference. This function will dispatch on the | |||
| 1264 | first match for C<$value>. It is possible to have a catch-all by providing an | |||
| 1265 | additional subroutine reference as the final argument to C<match_on_type>. | |||
| 1266 | ||||
| 1267 | =back | |||
| 1268 | ||||
| 1269 | =head2 Type Coercion Constructors | |||
| 1270 | ||||
| 1271 | You can define coercions for type constraints, which allow you to | |||
| 1272 | automatically transform values to something valid for the type | |||
| 1273 | constraint. If you ask your accessor to coerce, then Moose will run | |||
| 1274 | the type-coercion code first, followed by the type constraint | |||
| 1275 | check. This feature should be used carefully as it is very powerful | |||
| 1276 | and could easily take off a limb if you are not careful. | |||
| 1277 | ||||
| 1278 | See the L</SYNOPSIS> for an example of how to use these. | |||
| 1279 | ||||
| 1280 | =over 4 | |||
| 1281 | ||||
| 1282 | =item B<< coerce 'Name' => from 'OtherName' => via { ... } >> | |||
| 1283 | ||||
| 1284 | This defines a coercion from one type to another. The C<Name> argument | |||
| 1285 | is the type you are coercing I<to>. | |||
| 1286 | ||||
| 1287 | =item B<from 'OtherName'> | |||
| 1288 | ||||
| 1289 | This is just sugar for the type coercion construction syntax. | |||
| 1290 | ||||
| 1291 | It takes a single type name (or type object), which is the type being | |||
| 1292 | coerced I<from>. | |||
| 1293 | ||||
| 1294 | =item B<via { ... }> | |||
| 1295 | ||||
| 1296 | This is just sugar for the type coercion construction syntax. | |||
| 1297 | ||||
| 1298 | It takes a subroutine reference. This reference will be called with | |||
| 1299 | the value to be coerced in C<$_>. It is expected to return a new value | |||
| 1300 | of the proper type for the coercion. | |||
| 1301 | ||||
| 1302 | =back | |||
| 1303 | ||||
| 1304 | =head2 Creating and Finding Type Constraints | |||
| 1305 | ||||
| 1306 | These are additional functions for creating and finding type | |||
| 1307 | constraints. Most of these functions are not available for | |||
| 1308 | importing. The ones that are importable as specified. | |||
| 1309 | ||||
| 1310 | =over 4 | |||
| 1311 | ||||
| 1312 | =item B<find_type_constraint($type_name)> | |||
| 1313 | ||||
| 1314 | This function can be used to locate the L<Moose::Meta::TypeConstraint> | |||
| 1315 | object for a named type. | |||
| 1316 | ||||
| 1317 | This function is importable. | |||
| 1318 | ||||
| 1319 | =item B<register_type_constraint($type_object)> | |||
| 1320 | ||||
| 1321 | This function will register a L<Moose::Meta::TypeConstraint> with the | |||
| 1322 | global type registry. | |||
| 1323 | ||||
| 1324 | This function is importable. | |||
| 1325 | ||||
| 1326 | =item B<normalize_type_constraint_name($type_constraint_name)> | |||
| 1327 | ||||
| 1328 | This method takes a type constraint name and returns the normalized | |||
| 1329 | form. This removes any whitespace in the string. | |||
| 1330 | ||||
| 1331 | =item B<create_type_constraint_union($pipe_separated_types | @type_constraint_names)> | |||
| 1332 | ||||
| 1333 | This can take a union type specification like C<'Int|ArrayRef[Int]'>, | |||
| 1334 | or a list of names. It returns a new | |||
| 1335 | L<Moose::Meta::TypeConstraint::Union> object. | |||
| 1336 | ||||
| 1337 | =item B<create_parameterized_type_constraint($type_name)> | |||
| 1338 | ||||
| 1339 | Given a C<$type_name> in the form of C<'BaseType[ContainerType]'>, | |||
| 1340 | this will create a new L<Moose::Meta::TypeConstraint::Parameterized> | |||
| 1341 | object. The C<BaseType> must exist already exist as a parameterizable | |||
| 1342 | type. | |||
| 1343 | ||||
| 1344 | =item B<create_class_type_constraint($class, $options)> | |||
| 1345 | ||||
| 1346 | Given a class name this function will create a new | |||
| 1347 | L<Moose::Meta::TypeConstraint::Class> object for that class name. | |||
| 1348 | ||||
| 1349 | The C<$options> is a hash reference that will be passed to the | |||
| 1350 | L<Moose::Meta::TypeConstraint::Class> constructor (as a hash). | |||
| 1351 | ||||
| 1352 | =item B<create_role_type_constraint($role, $options)> | |||
| 1353 | ||||
| 1354 | Given a role name this function will create a new | |||
| 1355 | L<Moose::Meta::TypeConstraint::Role> object for that role name. | |||
| 1356 | ||||
| 1357 | The C<$options> is a hash reference that will be passed to the | |||
| 1358 | L<Moose::Meta::TypeConstraint::Role> constructor (as a hash). | |||
| 1359 | ||||
| 1360 | =item B<create_enum_type_constraint($name, $values)> | |||
| 1361 | ||||
| 1362 | Given a enum name this function will create a new | |||
| 1363 | L<Moose::Meta::TypeConstraint::Enum> object for that enum name. | |||
| 1364 | ||||
| 1365 | =item B<create_duck_type_constraint($name, $methods)> | |||
| 1366 | ||||
| 1367 | Given a duck type name this function will create a new | |||
| 1368 | L<Moose::Meta::TypeConstraint::DuckType> object for that enum name. | |||
| 1369 | ||||
| 1370 | =item B<find_or_parse_type_constraint($type_name)> | |||
| 1371 | ||||
| 1372 | Given a type name, this first attempts to find a matching constraint | |||
| 1373 | in the global registry. | |||
| 1374 | ||||
| 1375 | If the type name is a union or parameterized type, it will create a | |||
| 1376 | new object of the appropriate, but if given a "regular" type that does | |||
| 1377 | not yet exist, it simply returns false. | |||
| 1378 | ||||
| 1379 | When given a union or parameterized type, the member or base type must | |||
| 1380 | already exist. | |||
| 1381 | ||||
| 1382 | If it creates a new union or parameterized type, it will add it to the | |||
| 1383 | global registry. | |||
| 1384 | ||||
| 1385 | =item B<find_or_create_isa_type_constraint($type_name)> | |||
| 1386 | ||||
| 1387 | =item B<find_or_create_does_type_constraint($type_name)> | |||
| 1388 | ||||
| 1389 | These functions will first call C<find_or_parse_type_constraint>. If | |||
| 1390 | that function does not return a type, a new anonymous type object will | |||
| 1391 | be created. | |||
| 1392 | ||||
| 1393 | The C<isa> variant will use C<create_class_type_constraint> and the | |||
| 1394 | C<does> variant will use C<create_role_type_constraint>. | |||
| 1395 | ||||
| 1396 | =item B<get_type_constraint_registry> | |||
| 1397 | ||||
| 1398 | Returns the L<Moose::Meta::TypeConstraint::Registry> object which | |||
| 1399 | keeps track of all type constraints. | |||
| 1400 | ||||
| 1401 | =item B<list_all_type_constraints> | |||
| 1402 | ||||
| 1403 | This will return a list of type constraint names in the global | |||
| 1404 | registry. You can then fetch the actual type object using | |||
| 1405 | C<find_type_constraint($type_name)>. | |||
| 1406 | ||||
| 1407 | =item B<list_all_builtin_type_constraints> | |||
| 1408 | ||||
| 1409 | This will return a list of builtin type constraints, meaning those | |||
| 1410 | which are defined in this module. See the L<Default Type Constraints> | |||
| 1411 | section for a complete list. | |||
| 1412 | ||||
| 1413 | =item B<export_type_constraints_as_functions> | |||
| 1414 | ||||
| 1415 | This will export all the current type constraints as functions into | |||
| 1416 | the caller's namespace (C<Int()>, C<Str()>, etc). Right now, this is | |||
| 1417 | mostly used for testing, but it might prove useful to others. | |||
| 1418 | ||||
| 1419 | =item B<get_all_parameterizable_types> | |||
| 1420 | ||||
| 1421 | This returns all the parameterizable types that have been registered, | |||
| 1422 | as a list of type objects. | |||
| 1423 | ||||
| 1424 | =item B<add_parameterizable_type($type)> | |||
| 1425 | ||||
| 1426 | Adds C<$type> to the list of parameterizable types | |||
