public RJ()

Method Detail

exit

public static void exit(int status)

Terminates the currently running RJ program. The argument serves as a status code; by convention, a nonzero status code indicates abnormal termination. This method never returns normally.

Parameters:

status - The exit status.

nap

public static void nap(long millis)

Invokes nap(long,int) on nap(millis,0).

Parameters:

millis - the length of time to sleep in milliseconds.

nap

public static void nap(long millis,
                       int nanos)

Causes the currently executing thread to sleep (cease execution) for the specified number of milliseconds plus the specified number of nanoseconds. nap is just like Java's Thread.sleep except that nap catches any InterruptedException. Reminder: Java's Thread.sleep throws IllegalArgumentException for negative millis or nanos out of range 0-999999.

Parameters:

millis - the length of time to sleep in milliseconds.

nanos - 0-999999 additional nanoseconds to sleep.

yield

public static void yield()

Causes the currently executing thread to temporarily pause and allow other threads to execute.

registerQuiescenceAction

public static void registerQuiescenceAction(OpProxy cap)
                                     throws QuiescenceRegistrationException

Registers the quiescence action. The argument is the operation that is invoked implicitly via send when the RJ program quiesces.

Parameters:

cap - The quiescence operation.

Throws:

QuiescenceRegistrationException - any problems.
