NC 测试代码执行效率小工具

package fei.time.test;

import java.io.PrintStream;

import nc.bs.logging.NCSysOutWrapper;

public class TimeFei {
    
    
	private static Long lastTime;
	public static void fei(Long currTime,boolean isnull){
    
    
		if (isnull) {
    
    
			lastTime = null;
		}
		if(lastTime != null){
    
    
			StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();
			String stack = stackTrace[2].toString();
			PrintStream ps = System.out;
			if(ps instanceof NCSysOutWrapper){
    
    
				ps = ((NCSysOutWrapper) ps).getSysStream();
			}
			ps.println(stack+"-----耗时:"+(currTime - lastTime));
		}
		lastTime = currTime;
	}
}

除了第一句,参数为true以外,需要计时第二个地方false,然后哪里要计时就复制一句,方便多了
