类 TimeService

java.lang.Object

com.fr.third.jgroups.util.TimeService

所有已实现的接口:

java.lang.Runnable

public class TimeService
extends java.lang.Object
implements java.lang.Runnable

Provides a coarse grained time service. Registers a timer task which calls and caches System.currentTimeMillis() and returns the cached value. This is way faster than calling System.currentTimeMillis() many times, e.g. for each received message. The granularity (interval) can be chosen by the user.

从以下版本开始:
