tcl::transform::counter - Counter transformation
The tcl::transform::counterr package provides a command creating a channel transformation which passes the read and written bytes through unchanged (like tcl::transform::identity), but additionally counts the bytes it has seen for each direction and stores these counts in Tcl variables specified at construction time.
Related transformations in this module are tcl::transform::adler32, tcl::transform::crc32, tcl::transform::identity, and tcl::transform::observe.
The internal TclOO class implementing the transform handler is a sub-class of the tcl::transform::core framework.
This command creates a counter transformation on top of the channel chan and returns its handle. The accepted options are
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.
When proposing code changes, please provide unified diffs, i.e the output of diff -u.
Note further that attachments are strongly preferred over inlined patches. Attachments can be made by going to the Edit form of the ticket immediately after its creation, and then using the left-most button in the secondary navigation bar.
