Detailed Description

Provides access to a "virtual" device that accepts input data from a file rather than streaming from a physical device.

Constructor & Destructor Documentation

VirtualDeviceAdapter()

com.glneurotech.devices.common.VirtualDeviceAdapter.VirtualDeviceAdapter	(	IDaqDevice	device,
		RingBufferTransport	bufferTransport,
		GlntStream	inputStream
	)		throws IOException

Virtual device adapter.

Parameters

device	Take an IDaqDevice.
bufferTransport	Take a RingBufferTransport.
inputStream	Take a GlntStream.

Exceptions

IOException

Member Function Documentation

close()

final void com.glneurotech.devices.common.VirtualDeviceAdapter.close

(

)

throws IOException

Close the file or stop acquisition and disconnect the device.

Exceptions

IOException

feedNextChunk() [1/2]

final void com.glneurotech.devices.common.VirtualDeviceAdapter.feedNextChunk

(

)

throws IOException

Streams the next chunk of data to the virtual device.

feedNextChunk() [2/2]

final void com.glneurotech.devices.common.VirtualDeviceAdapter.feedNextChunk

(

int

chunkSize

)

throws IOException

Streams a chunk of data of a specified length to the virtual device.

Parameters

chunkSize

The number of bytes to stream to the device.

getBaseDevice()

final IDaqDevice com.glneurotech.devices.common.VirtualDeviceAdapter.getBaseDevice

(

)

The underlying DaqDevice object receiving input data from the file.

getEndOfFileReached()

final boolean com.glneurotech.devices.common.VirtualDeviceAdapter.getEndOfFileReached

(

)

Indicates when the end of the input file has been reached and there is no more data to feed to the device.

Member Data Documentation

DefaultChunkSize

final int com.glneurotech.devices.common.VirtualDeviceAdapter.DefaultChunkSize = 32767

static

The default number of bytes that will be read from the input file and fed to the virtual device input stream. This value is 32,767.
