Constructor Detail

RawDataSampleBuffer

protected RawDataSampleBuffer(int bufferSize,
                              int fftSize)

Instantiates a new raw data sample buffer.

Parameters:

bufferSize - the buffer size

fftSize - the fft size

Method Detail

connectionEventPerformed

public void connectionEventPerformed(ConnectionEvent e)

Implementation starts/stops disruptor.

Specified by:

connectionEventPerformed in interface ConnectionEventListener

Parameters:

e - the e

addSample

public abstract void addSample(SAMPLE sample)

Adds the sample.

Parameters:

sample - the sample

addSampleImpl

protected void addSampleImpl(double... sample)

Adds the sample impl.

Parameters:

sample - the sample

getSnapshot

public double[] getSnapshot()

Gets the snapshot.

Returns:

the snapshot

clear

public void clear()

Clear.

tune

public void tune()

When invoked the number of samples will be counted. When stopTuning() is invoked the time taken to process the total number of samples taken during that time will be used to resize the sample buffer.

stopTuning

public void stopTuning()

Invoked after a period of time after invoking tune(). Will resize the queue to represent ~ 1 second's worth of data based upon the total number of samples received during tuning.

getBufferSize

public int getBufferSize()

Gets the buffer size.

Returns:

the buffer size

setBufferSize

public void setBufferSize(int bufferSize)

Sets the buffer size.

Parameters:

bufferSize - the new buffer size

getFftSize

public int getFftSize()

Gets the fft size.

Returns:

the fft size

setFftSize

public void setFftSize(int fftSize)

Sets the fft size.

Parameters:

fftSize - the new fft size
