SYNOPSIS

package require tcl::transform::core ?1?
package require tcl::transform::identity ?1?
::tcl::transform::identity chan
________________________________________________________________________________________________________________
DESCRIPTION
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.
API
::tcl::transform::identity chan
This command creates an identity transformation on top of the channel chan and returns its handle.
