Tie::RefHash - Use references as hash keys
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::...ETHER/Tie-RefHash-1.40 - 10 Oct 2020 20:40:27 UTC
Tie::RefHash::Weak - A Tie::RefHash subclass with weakened references in the keys.
The Tie::RefHash module can be used to access hashes by reference. This is useful when you index by object, for example. The problem with Tie::RefHash, and cross indexing, is that sometimes the index should not contain strong references to the objecs...NUFFIN/Tie-RefHash-Weak-0.09 - 18 Oct 2008 04:18:23 UTC
Class::Ref - Automatic OO wrapping of container references
Class::Ref provides an OO wrapping layer around Hash and Array references. Part of the magic is that it does this deeply and across array/hash boundaries....MYDMNSN/Class-Ref-0.06 - 23 Nov 2017 02:43:23 UTC
Tie::Util - Utility functions for fiddling with tied variables
This module provides a few subroutines for examining and modifying tied variables, including those that hold weak references to the objects to which they are tied (weak ties). It also provides tie constructors in the "to::" namespace, so that you can...SPROUT/Tie-Util-0.04 - 01 Feb 2015 21:21:30 UTC
