Sample code for using handler to connect
Alternatively, you can create a SessionHandler object without connecting to a session. You then use that session handler to connect to a session. For example:
monitor SessionExample2 {
context mainContext := context.current();
action onload() {
com.apama.session.SessionHandler sessionHandler :=
(new com.apama.session.SessionHandlerFactory).create(mainContext);
sessionHandler.connect("MySession", "MyTransport");
...
}
}
Typically, you obtain a session handler object without connecting when you want to set parameters, set callbacks, or override default error handling before you connect to a session. See
Setting session callbacks,
Setting session parameters, and
Overriding default error handling for sessions.
Session handler objects must be initialized with a factory object before they can be used. For example, the following code does not work:
monitor IncorrectSessionExample {
context mainContext := context.current();
com.apama.session.SessionHandler sessionHandler;
action onload() {
// This will not work:
sessionHandler.connect(mainContext, "MySession", "MyTransport");
...
}
}
