8.157 Tie::Scalar, Tie::StdScalar

Provides some skeletal methods for scalar-tying classes. The basic Tie::Scalar package provides a new method, as well as methods TIESCALAR, FETCH, and STORE. The Tie::StdScalar package inherits from Tie::Scalar and causes scalars tied to it to behave like the built-in scalars, allowing for selective overloading of methods. The new method is provided as backup in case a class has no TIESCALAR method.

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

• TIESCALAR
• DESTROY
• FETCH
• STORE
