Class JavaWebStartState

java.lang.Object

org.glassfish.appclient.server.core.jws.JavaWebStartState

public class JavaWebStartState
extends Object

Models the state (and transitions) related to Java Web Start support of app clients for a given client.

As an app is enabled, disabled, suspended, or resumed, the state of how Java Web Start should respond is different. What transitions are permitted in each state is also enforced.

Implementation note: I tried recording the valid transitions (action plus new state) as part of the state value definitions themselves in the enum. This did not seem to work; in any Transition values for earlier states, references to states defined later in the enum were null! It's probably a little cleaner design to keep the states and the set of valid transitions separate from each other anyway.
