public class ProcessInterruptedException extends java.lang.Error
This is thrown if a process is interrupted whilst blocked during synchronisation - processes should never be interrupted.Description
This is caused by accessing the Java thread executing a JCSP process and invoking its java.lang.Thread.interrupt() method. If this is done to a process blocked on a JCSP synchronisation primitive (such as a channel communication or timeout), the process will wake up prematurely -- invalidating the semantics of that primitive. The wake up is intercepted and thisError
is thrown.Some browsers, when shutting down an applet, may do this to processes spawned by an
ActiveApplet
that have not died naturally. Alternatively, this may be raised by processes stopped prematurely as a result of a call to Parallel.destroy, or by calling stop on the ProcessManager responsible for the process (or network).- See Also:
