Method Detail

getAlsaDataLineMixer

protected AlsaDataLineMixer getAlsaDataLineMixer()

getAlsaPcm

protected AlsaPcm getAlsaPcm()

getAlsaStreamType

protected abstract int getAlsaStreamType()

Returns the ALSA stream type of this line. Subclasses must implement this method to return either AlsaPcm.SND_PCM_STREAM_PLAYBACK or AlsaPcm.SND_PCM_STREAM_CAPTURE. The return value is used by this class to decide if it has to deal with a source (PLAYBACK) or target (CAPTURE) data line.

getSwapBytes

protected boolean getSwapBytes()

getBytesPerSample

protected int getBytesPerSample()

openImpl

protected void openImpl()
                 throws LineUnavailableException

Description copied from class: TLine

Subclasses should override this method.

Overrides:

openImpl in class TLine

Throws:
