Tie::Hash

Provides skeletal methods for hash-tying classes. Tie::Hash provides a new method, as well as the methods TIEHASH, EXISTS, and CLEAR. The new method is provided as backup in case a class has no TIEHASH method.

To write your own tied hashes, the methods listed here are required. See the perltie manpage for more detailed information and for examples.
