All Implemented Interfaces:

Receiver

Enclosing class:

SysMLConcurrentDirector

public class SysMLConcurrentDirector.SysMLAReceiver
extends Mailbox

Variant of a Mailbox that overrides the put() method to divert the input to the queue associated with the actor and then provides a method to really put a token into a receiver. If the containing port has a boolean-valued attribute named "flow", then the behavior is quite different. First, a put updates the value of the receiver immediately in addition to putting a "change event" on the event queue. Second, the receiver value is persistent. A get() does not clear the receiver.
