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. Tie::RefHash's
|
|
internal structures contain strong references to the key, and provide no
|
|
convenient means to make those references weak.
|
|
|
|
This subclass of Tie::RefHash has weak keys, instead of strong ones. The
|
|
values are left unaltered, and you'll have to make sure there are no strong
|
|
references there yourself.
