Hash::Case::Preserve(3pm) User Contributed Perl Documentation Hash::Case::Preserve(3pm)
NAME
Hash::Case::Preserve - hash with enforced lower cased keys
INHERITANCE
Hash::Case::Preserve
is a Hash::Case
is a Tie::StdHash
SYNOPSIS
use Hash::Case::Preserve;
tie my(%cphash), 'Hash::Case::Preserve';
$cphash{StraNGeKeY} = 3;
print keys %cphash; # StraNGeKeY
print $cphash{strangekey}; # 3
print $cphash{STRANGEKEY}; # 3
DESCRIPTION
Hash::Case::Preserve extends Hash::Case, which lets you play various trics with hash keys. This extension implements a fake hash which is
case-insentive. The keys are administered in the casing as they were used: case-insensitive but case-preserving.
METHODS
Constructors
$obj->addHashData(HASH)
See "Constructors" in Hash::Case
$obj->addPairs(PAIRS)
See "Constructors" in Hash::Case
$obj->setHash(HASH)
See "Constructors" in Hash::Case
tie(HASH, 'Hash::Case::Preserve', [VALUES,] OPTIONS)
Define HASH to be case insensitive, but case preserving. The hash is initialized with the VALUES, specified as ref-array (passing a
list of key-value pairs) or ref-hash.
OPTIONS is a list of key/value pairs, which specify how the hash must handle preservation. Current options:
-Option--Default
keep 'LAST'
keep => 'FIRST' | 'LAST'
Which casing is the preferred casing? The FIRST appearance or the LAST. Only stores will affect the casing, deletes will undo the
definition. Defaults to LAST, which is slightly faster.
