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.
