Class JDIEventMonitor

java.lang.Object

java.lang.Thread

stdlib.JDIEventMonitor

All Implemented Interfaces:

Runnable

class JDIEventMonitor
extends Thread

Monitor incoming JDI events for a program running in the JVM and print out trace/debugging information. This is a simplified version of EventThread.java from the Trace.java example in the demo/jpda/examples.jar file in the JDK. Andrew Davison: The main addition is the use of the ShowCodes and ShowLines classes to list the line being currently executed. James Riely: See comments in class Trace.
