com.samskivert.util.RepeatCallTracker

public class RepeatCallTracker
extends Object

A class used to debug situations where a method that should be called once and only once is being called again later and one wishes to report the stack trace of the first and current calling on any repeat callings. Note: this object is not thread safe. If the multiple callings may take place on different threads, you must synchronize the calls to checkCall(java.lang.String) yourself.
