Tie::Hash::MultiValue allows you to have hashes which store their values
in anonymous arrays, appending any new value to the already-existing ones.
This means that you can store as many items as you like under a single key,
and access them all at once by accessing the value stored under the key.
acsccid is a PC/SC driver for Linux/Mac OS X and it supports ACS CCID
smart card readers. This library provides a PC/SC IFD handler
implementation and communicates with the readers through the PC/SC Lite
resource manager (pcscd).
This Perl module presents hashes in sorted order.
Tie::Hash::TwoWay will take a list of one-way associations and
transparently create their reverse. For instance, say you have a list
of machines, and a list of classes that each machine belongs to.
Tie::Hash::TwoWay will take the machines, one by one, with an associated
array reference of class names, and build the reverse mapping of classes
to machines. All the mappings are stored as hashes. You can access the
secondary mappings as if they were hash keys in their own right.
Tie::IxHash is a perl module implementing ordered in-memory associative arrays.
Perl module which implements an ordered hash-like object. It's a cross between
a Perl hash and a linked list. Use it whenever you want the speed and structure
of a Perl hash, but the orderedness of a list.
This modules causes any warnings produced by test scripts to be
captured and stored. It automatically adds an extra test that will run
when your script ends to check that there were no warnings. If there
were any warnings, the test will give a "not ok" and diagnostics of
where, when and what the warning was, including a stack trace of what
was going on when the it occurred.
This module provides the ability to use references as hash keys if you
first "tie" the hash variable to this module. Normally, only the keys
of the tied hash itself are preserved as references; to use references
as keys in hashes-of-hashes, use Tie::RefHash::Nestable, included as
part of Tie::RefHash.
It is implemented using the standard perl TIEHASH interface. Please
see the "tie" entry in perlfunc(1) and perltie(1) for more information.
The Nestable version works by looking for hash references being stored
and converting them to tied hashes so that they too can have references
as keys. This will happen without warning whenever you store a refer-
ence to one of your own hashes in the tied hash.
