Class Timer

java.lang.Object

org.apache.logging.log4j.util.Timer

All Implemented Interfaces:

java.io.Serializable, StringBuilderFormattable

public class Timer
extends java.lang.Object
implements java.io.Serializable, StringBuilderFormattable

Primarily used in unit tests, but can be used to track elapsed time for a request or portion of any other operation so long as all the timer methods are called on the same thread in which it was started. Calling start on multiple threads will cause the the times to be aggregated.
