Constructor and Description
SingleTaskSession(SessionTask onlySessionTask, String sessionId, ConcurrentMap<String,Session> sessions) Constructs a SingleTaskSession that has the task to execute supplied on construction.

Method Summary

Modifier and Type	Method and Description
boolean	isAcceptingTasks() The SingleWorker can only process one request so the initial construction of it already has the request in it and no more can be added, therefore this method always return false.

isAcceptingTasks

public boolean isAcceptingTasks()
