DESCRIPTION

This module provides a callback-based API to Term::Filter. The desired callbacks can just be passed into the constructor of this class, rather than requiring a new class to be manually defined. This class consumes the Term::Filter role, so the rest of the documentation in that module applies here.

ATTRIBUTES

callbacks

A hashref of callbacks for Term::Filter. The keys are callback names and the values are coderefs to call for those callbacks.
