Examples of com.sun.sgs.app.ClientSessionListener

com.sun.sgs.app.ClientSessionListener
Listener for messages sent from an associated client session to the server.
An implementation of a {@code ClientSessionListener} shouldimplement the {@link Serializable} interface, so that sessionlisteners can be stored persistently. If a given listener has mutable state, that listener should also implement the {@link ManagedObject} interface.
The methods of this listener are called within the context of a {@link Task} being executed by the {@link TaskManager}. If, during such an execution, a task invokes one of this listener's methods and that method throws an exception, that exception implements {@link ExceptionRetryStatus}, and its {@link ExceptionRetryStatus#shouldRetry shouldRetry} method returns{@code true}, then the {@code TaskManager} will makefurther attempts to retry the task that invoked the listener's method. It will continue those attempts until either an attempt succeeds or it notices an exception is thrown that is not retryable.
For a full description of task execution behavior, see the documentation for {@link TaskManager#scheduleTask(Task)}.
