See "SYNOPSIS" in Config::Model::AnyId DESCRIPTION
This class provides hash elements for a Config::Model::Node. The hash index can either be en enumerated type, a boolean, an integer or a string. CONSTRUCTOR
HashId object should not be created directly. Hash model declaration See model declaration section from Config::Model::AnyId. Methods get_type Returns "hash". fetch_size Returns the number of elements of the hash. firstkey Returns the first key of the hash. Behaves like "each" core perl function. nextkey Returns the next key of the hash. Behaves like "each" core perl function. swap ( key1 , key2 ) Swap the order of the 2 keys. Ignored for non ordered hash. move ( key1 , key2 ) Rename key1 in key2. move_after ( key_to_move [ , after_this_key ] ) Move the first key after the second one. If the second parameter is omitted, the first key is placed in first position. Ignored for non ordered hash. move_up ( key ) Move the key up in a ordered hash. Attempt to move up the first key of an ordered hash will be ignored. Ignored for non ordered hash. move_down ( key ) Move the key down in a ordered hash. Attempt to move up the last key of an ordered hash will be ignored. Ignored for non ordered hash. load_data ( hash_ref | array_ref ) Load check_list as a hash ref for standard hash. Ordered hash should be loaded with an array ref or with a hash containing a special "__order" element. E.g. loaded with either: [ a => 'foo', b => 'bar' ] or { __order => ['a','b'], b => 'bar', a => 'foo' } AUTHOR
