Method Detail

getAlsaStreamType

protected int getAlsaStreamType()

Description copied from class: AlsaBaseDataLine

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.
