  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<org.tentackle.task.Task>, java.lang.Runnable, org.tentackle.task.Task
    public class SessionKeepAliveTask
extends org.tentackle.task.AbstractTask
    The task to keep a session alive.
    The task uses the ExecutorService to spawn asynchroneous pings. This is necessary because a remote session may block on slow or bad communication lines which should not block the whole task dispatcher.
