The tcl::transform::core package provides a TclOO class implementing common behaviour needed by virtually every reflected or virtual channel transformation (initialization, finalization).

This class expects to be used as either superclass of a concrete channel class, or to be mixed into such a class.

Class API

Instance API

The API of transform core instances provides only two methods, both corresponding to transform handler commands (For reference see TIP 230). They expect to be called from whichever object instance the transform core was made a part of.
