=head1 NAME

Bio::Factory::SeqAnalysisParserFactoryI - interface describing objects capable
              of creating SeqAnalysisParserI compliant parsers

=head1 SYNOPSIS

    # initialize an object implementing this interface, e.g.
    $factory = Bio::Factory::SeqAnalysisParserFactory->new();
    # obtain a parser object
    $parser = $factory->get_parser(-input=>$inputobj,
                                   -params=>[@params],
		                   -method => $method);
    # $parser is an object implementing Bio::SeqAnalysisParserI
    # annotate sequence with features produced by parser
    while(my $feat = $parser->next_feature()) {
	$seq->add_SeqFeature($feat);
    }

=head1 DESCRIPTION

This is an interface for factory classes capable of instantiating
SeqAnalysisParserI implementing parsers.

The concept behind the interface is a generic analysis result parsing
in high-throughput automated sequence annotation pipelines. See
L<Bio::SeqAnalysisParserI> for more documentation of this concept.

=head2 get_parser

 Title   : get_parser
 Usage   : $factory->get_parser(-input=>$inputobj, 
                                [ -params=>[@params] ],
		                -method => $method)
 Function: Creates and returns a parser object for the given input and method.
           The type of input which is suitable depends on the implementation,
           but a good-style implementation should allow both file names and
           streams (filehandles).

           A particular implementation may not be able to create a parser for
           the requested method. In this case it shall return undef.

           Parameters (-params argument) are passed on to the parser object
           and therefore are specific to the parser to be created. An
           implementation of this interface should make this argument optional.
 Example :
 Returns : A Bio::SeqAnalysisParserI implementing object.
 Args    : B<input>  - object/file where analysis results are coming from,
	   B<params> - parameter to use when parsing/running analysis
	   B<method> - method of analysis
