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.

sort

Sort an ordered hash. Throws an error if called on a non ordered 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 is 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 is ignored. Ignored for non ordered hash.

load_data ( data => ( hash_ref | array_ref ) [ , check => ... , ... ])

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' }

load_data can also be called with a single ref parameter.
