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() [1/3]

com.glneurotech.devices.bioradio.VirtualDeviceAdapter.VirtualDeviceAdapter	(	IDaqDevice	device,
		RingBufferTransport	bufferTransport,
		FileInputStream	inputStream
	)		throws IOException

Constructor for virtual device adapter

Parameters

device	Take a IDaqDevice as parameter.
bufferTransport	Take a RingBufferTransport for the buffer transport parameter.
inputStream	Take a FileInputStream for the input stream parameter.

Exceptions

IOException

VirtualDeviceAdapter() [2/3]

com.glneurotech.devices.bioradio.VirtualDeviceAdapter.VirtualDeviceAdapter	(	IDaqDevice	device,
		RingBufferTransport	bufferTransport,
		FileInputStream	inputStream,
		LocalDateTime	recordingStartTime
	)		throws IOException

Overloaded constructor also takes a recording start time parameter

Parameters

device	Take a IDaqDevice as parameter.
bufferTransport	Take a RingBufferTransport for the buffer transport parameter.
inputStream	Take a FileInputStream for the input stream parameter.
recordingStartTime	Take a LocalDateTime for the recording start time.

Exceptions

IOException

VirtualDeviceAdapter() [3/3]

com.glneurotech.devices.bioradio.VirtualDeviceAdapter.VirtualDeviceAdapter	(	IDaqDevice	device,
		RingBufferTransport	bufferTransport,
		String	fileName
	)		throws IOException

Overloaded constructor takes an input file path string instead of a FileInputStream

Parameters

device	Take a IDaqDevice as parameter.
bufferTransport	Take a RingBufferTransport for the buffer transport parameter.
fileName	Take a string for the file name parameter.

Exceptions

IOException
