Detailed Description

template<class Listener>
class ACT::Basic_Listen_Monitor< Listener >

Base class for monitor service actions.

Collaborators:

• Basic_Listening_Task. Tasks register themselves here when they need to wake up.
• Scheduler. This action runs as a service within the scheduler. While this class uses no specific knowledge of its scheduler, it satisfies the requirements for a service action.
• wakeup_listener. Calls this is a function object to effect a wake-up. Responsibilities:
• Hold a record of each task that is waiting and won't again run until this class wakes it up.
• Run as a service in the same scheduler that each task is also in.
• When activated, wake up waiting tasks that have become ready. Note: this is not a postcondition for monitors generally. A monitor might only wake up a subset of its ready tasks at each activation.

Member Function Documentation

template<class Listener>

ACT_State ACT::Basic_Listen_Monitor< Listener >::wake_up_ready_tasks

(

)

[inline, protected]

Run through the ready list and wake up all the tasks on it, removing them from the ready list.

This is typically the last statement in the action body of a derived monitor.

Postcondition:

• return value is either Completed or Working

template<class Listener>

void ACT::Basic_Listen_Monitor< Listener >::add_ready_listener_task

(

wakeup_listener *

w

)

[inline, protected]

Add an item directly to the ready list, skipping readiness checking

Since the item is known to be ready, it needs no further examination. It need not appear in the parameter list, in contradistinction to add_waiting_listener_task.

template<class Listener>

void ACT::Basic_Listen_Monitor< Listener >::add_waiting_listener_task	(	Listener *	,
		wakeup_listener *
	)			[protected]

Add an item to the waiting list.
