The tcl::chan::events package provides a TclOO class implementing common behaviour needed by virtually every reflected or virtual channel supporting event driven IO. It is a sub-class of tcl::chan::core, inheriting all of its behaviour.

This class expects to be used as either superclass of a concrete channel class, or to be mixed into such a class.

Class API

Instance API

The API of channel event core instances provides only four methods, two corresponding to channel handler commands (For reference see TIP 219), and the other two for use by sub-classes to control event generation. They former expect to be called from whichever object instance the channel event core was made a part of.

Bugs, Ideas, Feedback

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.
