Create new Event processor builder.

Parameters:

target - web target to be used to call remote resource.

state - state shared with the owner of event processor instance.

clientExecutor - executor service used for consuming events and scheduling reconnects.

eventListener - event listener.

shutdownHandler - shutdown callback.

Returns:

new EventProcessor.Builder instance.

public void run()

Specified by:

run in interface Runnable

onEvent

public void onEvent(InboundEvent event)

Called by the event source when an inbound event is received. This listener aggregator method is responsible for invoking EventSource.onEvent(InboundEvent) method on the owning event source as well as for notifying all registered event listeners.

Specified by:

onEvent in interface EventListener

Parameters:

event - incoming inbound event.

awaitFirstContact

public void awaitFirstContact()

Await the initial contact with the SSE endpoint.
