Method Details

Add a callable to be invoked when the tasklet finishes. Return a connection handle that can be used in remove_join_callback()

The callback will be called like this:

     callback(tasklet, retval)

where tasklet is the tasklet that finished, and retval its return value (or None).

When a join callback is invoked, it is automatically removed, so calling remove_join_callback afterwards produces a KeyError exception.

Dictionary mapping message names to actions ('accept' or 'discard' or 'defer'). Should normally not be accessed directly by the programmer.

Remove a join callback previously added with add_join_callback

Method that executes the task.

Should be overridden in a subclass if no generator is passed into the constructor.

Send a message to be received by the tasklet as an event.

: Warning: Don't call this from another tasklet, only from the main loop! To send a message from another tasklet, yield a Message with a correctly set 'dest' parameter.

Method that should be called when a wait condition fires
