Class TimeoutAttr

  extended by org.inria.ns.reflex.processor.ForeignAttribute.Impl
      extended by org.inria.ns.reflex.processor.xcl.TimeoutAttr
All Implemented Interfaces:
Comparable, ForeignAttribute

public class TimeoutAttr
extends ForeignAttribute.Impl

The @xcl:timeout foreign attribute sets a timeout on an active tag.

If the active tag that hosts this attribute lasts more than the delay given in the value of this attribute, it will be interrupted. The $xcl:interrupted status property can be tested to check whether the active tag was interrupted or not.

When the timeout is reached, the $xcl:interrupt property signals to cancel their process, which is done in the method. Custom operations can also check periodically to cancel their process.

If the thread to interrupt is blocked, it will be interrupted in the conditions stated by the thread class.
