The restart method
In most cases, you implement the
but you could be able to optimize this process for some services. The following code shows the SocketGateway class
method:
restart
public void restart() {
stop();
start();
}
Responding to incoming messages
One or more listener threads respond to incoming messages (events). The threads must include code to dispatch the
messages to ColdFusion event gateway services, as follows:
1
Create a CFEvent instance.
Create a Map instance that contains the message and any other event gateway-specific information, and pass it to
2
the CFEvent
method.
