Constructor Details

RemoteUsbManager

public RemoteUsbManager(android.content.Context context)

Method Details

getReadSize

protected int getReadSize()

Specified by:

getReadSize in class UsbCloverManager<Void>

getMaxWriteDataSize

protected int getMaxWriteDataSize()

Specified by:

getMaxWriteDataSize in class UsbCloverManager<Void>

isUsbDeviceAttached

public static boolean isUsbDeviceAttached(android.content.Context context)

getVendorProductIds

protected android.util.Pair<Integer,Integer>[] getVendorProductIds()

Specified by:

getVendorProductIds in class UsbCloverManager<Void>

isInterfaceMatch

protected boolean isInterfaceMatch(android.hardware.usb.UsbInterface usbInterface)

Overrides:

isInterfaceMatch in class UsbCloverManager<Void>

getReadTimeOut

protected int getReadTimeOut()

Description copied from class: UsbCloverManager

Returns the amount of time to wait before read fails, 0 means wait forever.

Overrides:

getReadTimeOut in class UsbCloverManager<Void>

wrapWritePacket

protected byte[] wrapWritePacket(ByteBuffer outDataBuffer,
 int numBytesToTransfer)

Overrides:

wrapWritePacket in class UsbCloverManager<Void>

unwrapReadPacket

protected byte[] unwrapReadPacket(ByteBuffer inDataBuffer)

Overrides:

unwrapReadPacket in class UsbCloverManager<Void>

processOutputData

protected byte[] processOutputData(byte[] outputData,
 Void aVoid)

Description copied from class: UsbCloverManager

Optionally override this method to perform data processing on the output bytes before they are sent. The returned byte array is used for the data transfer, the implementation may choose to modify the byte array parameter or return a new byte array.

Overrides:

processOutputData in class UsbCloverManager<Void>

processInputData

protected UsbCloverManager.InputResult processInputData(byte[] inputData,
 ByteArrayOutputStream outputStream,
 Void params)

Description copied from class: UsbCloverManager

Optionally override this method to perform data processing on the input data bytes before they are returned. The implementation must write the desired output bytes to the ByteArrayOutputStream. Unlike UsbCloverManager.processOutputData(byte[], T) this function may be called multiple times in a single transfer depending on the return value of this function

Overrides:

processInputData in class UsbCloverManager<Void>

Parameters:

inputData - buffer containing bytes read from the USB device

outputStream - stream containing bytes that will be returned to the caller

params - additional parameters which may allow the implementation to modify the way the byte array is interpreted

Returns:

CONTINUE to request more USB device data, COMPLETE to return the received data or ERROR if something is wrong
