extends BaseTargetPreparer

java.lang.Object 中
↳	com.android.tradefed.targetprep.BaseTargetPreparer
	↳	com.android.tradefed.targetprep.companion.CompanionAllocator

负责分配和释放配套设备的基类

应实现getCompanionDeviceSelectionOptions()来描述条件分配配套设备所需的步骤

摘要

公共构造函数
`CompanionAllocator()`

公共方法
`void`	`setUp(ITestDevice device, IBuildInfo buildInfo)` 设置设备。
`void`	`tearDown(ITestDevice device, IBuildInfo buildInfo, Throwable e)`

受保护的方法
`abstract DeviceSelectionOptions`	`getCompanionDeviceSelectionOptions()` 描述配套设备的 `DeviceSelectionOptions`

public CompanionAllocator ()

public void setUp (ITestDevice device, 
                IBuildInfo buildInfo)

设置设备。

此方法的内部实现将请求配套设备，并进行分配。

参数
`device`	`ITestDevice`
`buildInfo`	`IBuildInfo`

抛出
`BuildError`
`DeviceNotAvailableException`
`TargetSetupError`

public void tearDown (ITestDevice device, 
                IBuildInfo buildInfo, 
                Throwable e)

抛出
`DeviceNotAvailableException`

protected abstract DeviceSelectionOptions getCompanionDeviceSelectionOptions ()

描述配套设备的 DeviceSelectionOptions

返回
`DeviceSelectionOptions`
