::tcl::transform::identity chan


The tcl::transform::identity package provides a command creating an identity channel transformation, which does nothing but pass the read and written bytes through it unchanged. Not really useful in an application, however as the prototypical observer transformation its code is a useful starting point for any other observers people may wish to write.

The transformations in this module which derived from identity's code are tcl::transform::adler32, tcl::transform::counter, tcl::transform::crc32, and tcl::transform::observe.

The internal TclOO class implementing the transform handler is a sub-class of the tcl::transform::core framework.
