swap

Parameters: "( key1 , key2 )"

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

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.

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.

Return 1 of some data was loaded.

get_info

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