编码约定

引用

1.每个方法都以方法名下一行的顶格大括号开始。

public DefaultMetricsTimer popTimer(DefaultMetricsTimer timer)
	{
		Stack<DefaultMetricsTimer> timerStack = getTimerStack();
		while (!timerStack.isEmpty()) {
			DefaultMetricsTimer temp = timerStack.pop();
			if (temp.equals(timer)) {
				return timer;
			}
			else {
				if (isThrowException()) {
					throw new MetricsException("Invalid stack timer " + temp);
				}
				else {
					LOGGER.warn("Invalid stack timer " + temp);
				}
			}
		}

		if (isThrowException()) {
			throw new MetricsException("Unable to find timer " + timer);
		}
		else {
			LOGGER.warn("Unable to find timer " + timer);
		}

		return null;
	}

2.每个方法不超过50行

3.返回组装对象，用先定义，然后return 定义引用的方式

public CorrelationInfo getCorrelationInfo()
	{
		CorrelationInfo correlationInfo = null;

		Stack<DefaultMetricsTimer> timerStack = getTimerStack();
		if (!timerStack.isEmpty()) {
			DefaultMetricsTimer metricsTimer = getTimerStack().peek();
			correlationInfo = metricsTimer.getCorrelationInfo();
		}
		else {
			if (LOGGER.isTraceEnabled()) {
				LOGGER.trace("Correlation information is unavailable");
			}
		}

		return correlationInfo;
	}
