tcl::transform::observe - Observer transformation, stream copy
The tcl::transform::observer package provides a command creating a channel transformation which passes the read and written bytes through unchanged (like tcl::transform::identity), but additionally copies the data it has seen for each direction into channels specified at construction time.
This command creates an observer transformation on top of the channel chan and returns its handle. The channel handles logr and logw are there the data is copied to.
This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category virtchannel of the Tcllib Trackers. Please also report any ideas for enhancements you may have for either package and/or documentation.
