LargeOutputReceiver

public class LargeOutputReceiver
extends Object implements IShellOutputReceiver

java.lang.Object
↳	com.android.tradefed.device.LargeOutputReceiver

A class designed to help run long running commands collect output.

The maximum size of the tmp file is limited to approximately maxFileSize. To prevent data loss when the limit has been reached, this file keeps set of tmp host files.

Summary

Public constructors
`LargeOutputReceiver(String descriptor, String serialNumber, long maxDataSize)` Creates a `LargeOutputReceiver`.

Public methods
`void`	`addOutput(byte[] data, int offset, int length)`
`void`	`cancel()` Cancels the command.
`void`	`clear()` Delete currently accumulated data, and then re-create a new file.
`void`	`delete()` Delete all accumulated data.
`void`	`flush()`
`InputStreamSource`	`getData()` Gets the collected output as a `InputStreamSource`.
`InputStreamSource`	`getData(int maxBytes)` Gets the last `maxBytes` of collected output as a `InputStreamSource`.
`InputStreamSource`	`getData(int maxBytes, int offset)` Gets the last `maxBytes` of collected output as a `InputStreamSource`.
`boolean`	`isCancelled()`

Public constructors

LargeOutputReceiver

public LargeOutputReceiver (String descriptor, 
                String serialNumber, 
                long maxDataSize)

Creates a LargeOutputReceiver.

Parameters
`descriptor`	`String`: the descriptor of the command to run. For logging only.
`serialNumber`	`String`: the serial number of the device. For logging only.
`maxDataSize`	`long`: the approximate max amount of data to keep.

Public methods

addOutput

public void addOutput (byte[] data, 
                int offset, 
                int length)
