Just like DynamicDispatchActor, except that the actual method dispatch is static through the closure passed to the initialize() method.

Method Detail

submit

DataflowVariable<java.lang.Object> submit(java.lang.Object... args)

A DataflowVariable is passed to the actor, which will bind it once the result is known.

Parameters:

args - The method parameters

Returns:

A Promise for the real result

submitAndWait

java.lang.Object submitAndWait(java.lang.Object... args)
                        throws java.lang.Throwable

A DataflowVariable is passed to the actor, which will bind it once the result is known. The method blocks waiting for the Promise to hold a value. The value is then returned back to the caller.

Parameters:

args - The method parameters

Returns:

The result of the internal method as returned when run in the internal actor's context

Throws:

java.lang.InterruptedException - If the current thread gets interrupted while waiting for the internal actor to respond

java.lang.Throwable - If the target method invoked asynchronously throws an exception.

onMessage

public void onMessage(java.lang.Object[] msg)

Handles incoming messages

Parameters:

msg - The message representing the requested method call

handleCurrentMessage

private static java.lang.Object handleCurrentMessage(java.lang.Object msg)

create

public static InternalActor create(java.lang.Object groupId)
