# Subprograms & Entries

### Element

- Goto spec in source

    function Element (Map: Wildcard_Level_Map;Key: String) return Log_Level;

Returns the loglevel element for given key.

### Element

- Goto spec in source

    function Element (Position: Cursor) return Log_Level;

Returns the loglevel element at given position.

### Find

- Goto spec in source

    function Find (Map: Wildcard_Level_Map;Key: String) return Cursor;

Returns the position for an element with specified key. If no element is found No_Element is returned.

### Lookup

- Goto spec in source

    function Lookup (Map: Wildcard_Level_Map;Key: String) return Cursor;

Returns the position of the element with the closest match to given key. This function considers wildcards when searching for an element. Example: Key | Element ------------------- Foo.* | Debug Foo.Bar | Alert A lookup for "Foo.Foo" has no exact match. The next closest match is "Foo.*" which will return the Debug element. Looking for "Foo" will return Debug since it matches the wildcard "Foo.*". If no exact and wildcard match is found No_Element is returned.

### Insert

- Goto spec in source

    procedure Insert (Map: in out Wildcard_Level_Map;Key:        String;Item:        Log_Level);

Insert given key/item pair into map. If given key is already present the associated item is replaced.

### Clear

- Goto spec in source

    procedure Clear (Map: in out Wildcard_Level_Map);

Clears the wildcard map.

### Length

- Goto spec in source

    function Length (Map: Wildcard_Level_Map) return Natural;

Return the number of elements in the map.
