Method Detail

premiere

public String premiere(ZMQ.Socket pipe)

Description copied from interface: ZActor.Actor

This is the grand premiere! Called before the creation of the first double and the sockets 2nd in the order call of the global acting.

Specified by:

premiere in interface ZActor.Actor

Parameters:

pipe - the backstage control pipe

Returns:

the name of the upcoming performance

createSockets

public List<ZMQ.Socket> createSockets(ZContext ctx,
                             Object... args)

Description copied from interface: ZActor.Actor

Creates and initializes sockets for the double. This is done at each creation of a new double. 3rd in the order call of the global acting. 1st in the order call of the new double.

Specified by:

createSockets in interface ZActor.Actor

Parameters:

ctx - the context used to create sockets

args - the arguments passed as parameters of the ZActor

Returns:

a list of created sockets that will be managed by the double. Not null.

start

public void start(ZMQ.Socket pipe,
         List<ZMQ.Socket> sockets,
         ZPoller poller)

Description copied from interface: ZActor.Actor

Called when the double is started, before the first loop. 4th in the order call of the global acting. 2nd in the order call of the new double.

Specified by:

start in interface ZActor.Actor

Parameters:

pipe - the backstage control pipe

sockets - the managed sockets that were created in the previous step

poller - the poller where to eventually register the sockets for events

looping

public long looping(ZMQ.Socket pipe,
           ZPoller poller)

Description copied from interface: ZActor.Actor

Called every time just before a loop starts. 5th in the order call of the global acting. 3nd in the order call of the new double. 1st in the order call of the new loop.

Specified by:

looping in interface ZActor.Actor

Parameters:

pipe - the backstage control pipe

poller - the poller of the double

Returns:

the timeout of the coming loop. -1 to block, 0 to not wait, > 0 to wait till max the returned duration in milliseconds

backstage

public boolean backstage(ZMQ.Socket pipe,
                ZPoller poller,
                int events)

Description copied from interface: ZActor.Actor

Called when the actor received a control message from its pipe during a loop. 2nd in the order call of the new loop.

Specified by:

backstage in interface ZActor.Actor

Parameters:

pipe - the backstage control pipe receiving the message

poller - the poller of the double.

events - the events source of the call

Returns:

true in case of success, false to stop the actor.

stage

public boolean stage(ZMQ.Socket socket,
            ZMQ.Socket pipe,
            ZPoller poller,
            int events)

Description copied from interface: ZActor.Actor

The actor received a message from the created sockets during a loop. 2nd ex-aequo in the order call of the new loop.

Specified by:

stage in interface ZActor.Actor

Parameters:

socket - the socket receiving the message

pipe - the backstage control pipe

poller - the poller of the double.

true in case of success, false to stop the actor.

looped

public boolean looped(ZMQ.Socket pipe,
             ZPoller poller)

Description copied from interface: ZActor.Actor

Called at the end of each loop. 3rd in the order call of the new loop.

Specified by:

looped in interface ZActor.Actor

Parameters:

pipe - the backstage control pipe

Returns:

true to continue with the current doppelganger, false to stop it.

closed
