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 reference to one of your own hashes in the tied hash.
