Hash::Case(3pm) User Contributed Perl Documentation Hash::Case(3pm)
NAME
Hash::Case - base class for hashes with key-casing requirements
INHERITANCE
Hash::Case
is a Tie::StdHash
Hash::Case is extended by
Hash::Case::Lower
Hash::Case::Preserve
Hash::Case::Upper
SYNOPSIS
use Hash::Case::Lower;
tie my(%lchash), 'Hash::Case::Lower';
$lchash{StraNGeKeY} = 3;
print keys %lchash; # strangekey
DESCRIPTION
Hash::Case is the base class for various classes which tie special treatment for the casing of keys. Be aware of the differences in
implementation: "Lower" and "Upper" are tied native hashes: these hashes have no need for hidden fields or other assisting data structured.
A case "Preserve" hash will actually create three hashes.
The following strategies are implemented:
o Hash::Case::Lower (native hash)
Keys are always considered lower case. The internals of this module translate any incoming key to lower case before it is used.
o Hash::Case::Upper (native hash)
Like the ::Lower, but then all keys are always translated into upper case. This module can be of use for some databases, which do
translate everything to capitals as well. To avoid confusion, you may want to have you own internal Perl hash do this as well.
o Hash::Case::Preserve
The actual casing is ignored, but not forgotten.
METHODS
Constructors
$obj->addHashData(HASH)
Add the data of a hash (passed as reference) to the created tied hash. The existing values in the hash remain, the keys are adapted to
the needs of the the casing.
$obj->addPairs(PAIRS)
Specify an even length list of alternating key and value to be stored in the hash.
$obj->setHash(HASH)
The functionality differs for native and wrapper hashes. For native hashes, this is the same as first clearing the hash, and then a
call to addHashData(). Wrapper hashes will use the hash you specify here to store the data, and re-create the mapping hash.
tie(HASH, TIE, [VALUES,] OPTIONS)
Tie the HASH with the TIE package which extends Hash::Case. The OPTIONS differ per implementation: read the manual page for the
package you actually use. The VALUES is a reference to an array containing key-value pairs, or a reference to a hash: they fill the
initial hash.
example:
my %x;
tie %x, 'Hash::Case::Lower';
$x{Upper} = 3;
print keys %x; # 'upper'
my @y = (ABC => 3, DeF => 4);
tie %x, 'Hash::Case::Lower', @y;
print keys %x; # 'abc' 'def'
my %z = (ABC => 3, DeF => 4);
tie %x, 'Hash::Case::Lower', \%z;
