Method Details

setSource

public void setSource(ShadowVisualizer.VisualizerSource source)

setDataCaptureListener

@Implementation
protected int setDataCaptureListener(Visualizer.OnDataCaptureListener listener,
 int rate,
 boolean waveform,
 boolean fft)

native_getSamplingRate

@Implementation
protected int native_getSamplingRate()

native_getWaveForm

@Implementation
protected int native_getWaveForm(byte[] waveform)

native_getFft

@Implementation
protected int native_getFft(byte[] fft)

native_getEnabled

@Implementation
protected boolean native_getEnabled()

native_setCaptureSize

@Implementation
protected int native_setCaptureSize(int size)

native_getCaptureSize

@Implementation
protected int native_getCaptureSize()

native_setEnabled

@Implementation
protected int native_setEnabled(boolean enabled)

native_getPeakRms

@Implementation
protected int native_getPeakRms(Visualizer.MeasurementPeakRms measurement)

native_release

@Implementation
protected void native_release()

triggerDataCapture

public void triggerDataCapture()

Trigger calls to the existing Visualizer.OnDataCaptureListener.

This is a no-op if the listener has not been set.

setState

public void setState(int newState)

Updates the state of the Visualizer itself.

This can be used e.g. to put the Visualizer in an unexpected state and cause an exception the next time the Visualizer is used.

setErrorCode

public void setErrorCode(int errorCode)

Sets the error code to override setter methods in this class.

When the error code is set to anything other than Visualizer.SUCCESS setters in the Visualizer will early-out and return that error code.
