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.
