NAME¶
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 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.
