# TibrvDispatcher

Class

## Declaration

    class com.tibco.tibrv.TibrvDispatcher
      extends java.lang.Thread

## Purpose

Dispatch events from a queue or queue group.

## Remarks

Upon creation, this thread class loops indefinitely, repeatedly dispatching a queue or queue group.

This class is a programming convenience. Programs can implement specialized dispatcher threads, and use them instead of this class.

## Exceptions

If the thread catches a TibrvException, it presents the `DISPATCHER.THREAD_EXITED` advisory on the process transport, and exits. (The program destroyed the queue or queue group object, so this thread can no longer dispatch it.)

If the thread catches an interruption (`java.lang.InterruptedException`), it presents the `DISPATCHER.THREAD_EXITED` advisory on the process transport, and exits.

## Interrupting a Dispatcher Thread

To interrupt a dispatcher thread in the Java implementation (see Tibrv.open()), use either the Java method `Thread.interrupt()` or `TibrvDispatcher.destroy()`.

In either the JNI (native) implementation or the Java implementation, you can interrupt a dispatcher thread by calling its `TibrvDispatcher.destroy()` method. Destroying the thread insures prompt thread exit—at the latest, after the return of a program callback method (if one is in progress).

Method | Description
TibrvDispatcher() | Create a dispatcher thread.

Constant | Description
`TibrvDispatcher.DEFAULT_NAME` | When the constructor does not receive a thread name, it gives the new dispatcher thread this default name.
