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.

sort

Sort an ordered hash. Throws an error if called on a non ordered hash.

insort

Parameters: key

Create a new element in the ordered hash while keeping alphabetical order of the keys

Returns the newly created element.

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

Parameters: ( key1 , key2 )

Swap the order of the 2 keys. Ignored for non ordered hash.

move

Parameters: ( key1 , key2 )

Rename key1 in key2.

Also also optional check parameter to disable warning:

 move ('foo','bar', check => 'no')

move_after

Parameters: ( 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

Parameters: ( 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

Parameters: ( 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

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

Load data 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' }

__skip_order parameter can be used if loading order is not important:

  { __skip_order => 1, b => 'bar', a => 'foo'}

load_data can also be called with a single ref parameter.

get_info

Returns a list of information related to the hash. See "get_info" in Config::Model::Value for more details.
