SYNOPSIS

14        use Hash::Case::Preserve;
15        tie my(%cphash), 'Hash::Case::Preserve';
16        $cphash{StraNGeKeY} = 3;
17        print keys %cphash;         # StraNGeKeY
18        print $cphash{strangekey};  # 3
19        print $cphash{STRANGEKEY};  # 3

DESCRIPTION

22       Hash::Case::Preserve extends Hash::Case, which lets you play various
23       trics with hash keys.  See Hash::Case for the other implementations.
24

METHODS

26       $obj->addHashData(HASH)
27
28           See "METHODS" in Hash::Case
29
30       $obj->addPairs(PAIRS)
31
32           See "METHODS" in Hash::Case
33
34       $obj->setHash(HASH)
35
36           See "METHODS" in Hash::Case
37
38       tie(HASH, 'Hash::Case::Preserve', [VALUES,] OPTIONS)
39
40           Define HASH to be case insensitive, but case preserving.  The hash
41           is initialized with the VALUES, specified as ref-array or ref-hash.
42
43           OPTIONS is a list of key/value pairs, which specify how the hash
44           must handle preservation.  Current options:
45
46            Option--Default
47            keep    <required>
48
49           . keep => => 'FIRST' | 'LAST'
50
51               Which casing is the prefered casing?  The FIRST appearance or
52               the LAST.  Only stores will affect the casing, deletes will
53               undo the definition.  Defaults to LAST, which is slightly
54               faster.
