分片监听器

public class ShardListener
extends CollectingTestListener implements ISupportGranularResults

java.lang.Object
↳	com.android.tradefed.result.CollectingTestListener
	↳	com.android.tradefed.invoker.ShardListener

一个ITestInvocationListener ，用于从调用分片（也称为在多个资源上并行运行的调用拆分）收集结果，并将它们转发到另一个侦听器。

公共构造函数

分片监听器

public ShardListener (ITestInvocationListener main)

创建一个ShardListener 。

参数
`main`	`ITestInvocationListener` ：应该转发结果的`ITestInvocationListener` 。为了防止与其他`ShardListener`发生冲突，该对象在转发结果时将在`main`上同步。并且只有在调用分片完成后才会发送结果。

公共方法

调用结束

public void invocationEnded (long elapsedTime)

参数
`elapsedTime`	`long`

调用失败

public void invocationFailed (FailureDescription failure)

参数
`failure`	`FailureDescription`

调用失败

public void invocationFailed (Throwable cause)

参数
`cause`	`Throwable`

调用开始

public void invocationStarted (IInvocationContext context)

参数
`context`	`IInvocationContext`

设置支持粒度结果

public void setSupportGranularResults (boolean enableGranularResults)

参数
`enableGranularResults`	`boolean`

`dataType`	`LogDataType`
`dataStream`	`InputStreamSource`
