Methods

27   get_type
28       Returns "hash".
29
30   fetch_size
31       Returns the number of elements of the hash.
32
33   sort
34       Sort an ordered hash. Throws an error if called on a non ordered hash.
35
36   insort
37       Parameters: key
38
39       Create a new element in the ordered hash while keeping alphabetical
40       order of the keys
41
42       Returns the newly created element.
43
44       Throws an error if called on a non ordered hash.
45
46   firstkey
47       Returns the first key of the hash. Behaves like "each" core perl
48       function.
49
50   nextkey
51       Returns the next key of the hash. Behaves like "each" core perl
52       function.
53
54   swap
55       Parameters: "( key1 , key2 )"
56
57       Swap the order of the 2 keys. Ignored for non ordered hash.
58
59   move
60       Parameters: "( key1 , key2 )"
61
62       Rename key1 in key2.
63
64       Also also optional check parameter to disable warning:
65
66        move ('foo','bar', check => 'no')
67
68   move_after
69       Parameters: "( key_to_move [ , after_this_key ] )"
70
71       Move the first key after the second one. If the second parameter is
72       omitted, the first key is placed in first position. Ignored for non
73       ordered hash.
74
75   move_up
76       Parameters: "( key )"
77
78       Move the key up in a ordered hash. Attempt to move up the first key of
79       an ordered hash is ignored. Ignored for non ordered hash.
80
81   move_down
82       Parameters: "( key )"
83
84       Move the key down in a ordered hash. Attempt to move up the last key of
85       an ordered hash is ignored. Ignored for non ordered hash.
86
87   load_data
88       Parameters: "( data => ( hash_ref | array_ref ) [ , check => ... , ...
89       ])"
90
91       Load data as a hash ref for standard hash.
92
93       Ordered hash should be loaded with an array ref or with a hash
94       containing a special "__order" element. E.g. loaded with either:
95
96         [ a => 'foo', b => 'bar' ]
97
98       or
99
100         { __order => ['a','b'], b => 'bar', a => 'foo' }
101
102       "__skip_order" parameter can be used if loading order is not important:
103
104         { __skip_order => 1, b => 'bar', a => 'foo'}
105
106       load_data can also be called with a single ref parameter.
107
108   get_info
109       Returns a list of information related to the hash. See "get_info" in
110       Config::Model::Value for more details.
