| Instance Variables | state | current execution state of the tasklet, one of the STATE_* contants. | 
| return_value | the value returned by the task function, or None. | |
| Class Variables | STATE_RUNNING | the tasklet function is currently executing code | 
| STATE_SUSPENDED | the tasklet function is currently waiting for an event | |
| STATE_MSGSEND | the tasklet function is currently sending a message | |
| STATE_ZOMBIE | the tasklet function has ended | 
| Method | __init__ | Launch a generator tasklet. | 
| Method | start | Starts the execution of the task, for use with tasklets | 
| Method | get_message_actions | Dictionary mapping message names to actions ('accept' or | 
| Method | run | Method that executes the task. | 
| Method | _invoke | Undocumented | 
| Method | _next_round | Undocumented | 
| Method | _dispatch_message | get next message that a tasklet wants to receive; discard | 
| Method | _update_wait_conditions | disarm wait conditions removed and arm new wait conditions | 
| Method | wait_condition_fired | Method that should be called when a wait condition fires | 
| Method | add_join_callback | Add a callable to be invoked when the tasklet finishes. | 
| Method | remove_join_callback | Remove a join callback previously added with add_join_callback | 
| Method | _join | Undocumented | 
| Method | send_message | Send a message to be received by the tasklet as an event. | 
| Parameters | gen | a generator object that implements the tasklet main body | 
| start | whether to automatically start running the tasklet in the constructorIf `gen` is omitted or None, runshould be 
overridden in a subclass. | 
Method that executes the task.
Should be overridden in a subclass if no generator is passed into the constructor.| Note | do NOT call this method directly; it is meant to be called by the tasklet framework. | |
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, *extra_args)
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 callingremove_join_callback
afterwards produces a KeyError exception.
add_join_callback
| Note | Don't call this from another tasklet, only from the main loop!  To send 
a message from another tasklet, yield a Messagewith a correctly 
set 'dest' parameter. | |
