|
+--jade.util.InputQueue
- public class InputQueue
- extends java.lang.Object
This class implements a FIFO queue of objects that can be put and got
in a synchronized way. This is useful when an external thread,
e.g. a GUI, has to communicate with an agent: The external thread
puts objects in the queue and the agent gets and processes them.
The queue can be associated to a Behaviour
. This
Behaviour will be restarted each time an object is inserted in the
queue.
