tcl::transform::identity - Identity transformation
SYNOPSIS
package require Tcl 8.6
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 appli‐
cation, 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::trans‐
form::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.
