CapturingAudioSink(AudioSink sink)

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`configure(Format inputFormat, int specifiedBufferSize, int[] outputChannels)`	Configures (or reconfigures) the sink.
`void`	`dump(Dumper dumper)`	Dumps the fields of the object using the `dumper`.
`void`	`flush()`	Flushes the sink, after which it is ready to receive buffers from a new playback position.
`boolean`	`handleBuffer(ByteBuffer buffer, long presentationTimeUs, int encodedAccessUnitCount)`	Attempts to process data from a `ByteBuffer`, starting from its current position and ending at its limit (exclusive).
`void`	`handleDiscontinuity()`	Signals to the sink that the next buffer may be discontinuous with the previous buffer.
`void`	`reset()`	Resets the sink, releasing any resources that it currently holds.

public CapturingAudioSink(AudioSink sink)
```
- Method Detail
  - configure
```
public void configure(Format inputFormat,
                      int specifiedBufferSize,
                      @Nullable
                      int[] outputChannels)
               throws AudioSink.ConfigurationException
```
    Description copied from interface: AudioSink
    
    Configures (or reconfigures) the sink.
    
    Specified by:
    
    configure in interface AudioSink
    
    Overrides:
    
    configure in class ForwardingAudioSink
    
    Parameters:
    
    inputFormat - The format of audio data provided in the input buffers.
    
    specifiedBufferSize - A specific size for the playback buffer in bytes, or 0 to infer a suitable buffer size.
    
    outputChannels - A mapping from input to output channels that is applied to this sink's input as a preprocessing step, if handling PCM input. Specify null to leave the input unchanged. Otherwise, the element at index i specifies index of the input channel to map to output channel i when preprocessing input buffers. After the map is applied the audio data will have outputChannels.length channels.
    
    Throws:
    
    AudioSink.ConfigurationException - If an error occurs configuring the sink.
  - handleDiscontinuity
```
public void handleDiscontinuity()
```
    Description copied from interface: AudioSink
    
    Signals to the sink that the next buffer may be discontinuous with the previous buffer.
    
    Specified by:
    
    handleDiscontinuity in interface AudioSink
    
    Overrides:
    
    handleDiscontinuity in class ForwardingAudioSink
  - handleBuffer
```
public boolean handleBuffer(ByteBuffer buffer,
                            long presentationTimeUs,
                            int encodedAccessUnitCount)
                     throws AudioSink.InitializationException,
                            AudioSink.WriteException
```
    Description copied from interface: AudioSink
    
    Attempts to process data from a ByteBuffer, starting from its current position and ending at its limit (exclusive). The position of the ByteBuffer is advanced by the number of bytes that were handled. AudioSink.Listener.onPositionDiscontinuity() will be called if presentationTimeUs is discontinuous with the last buffer handled since the last reset.
    Returns whether the data was handled in full. If the data was not handled in full then the same ByteBuffer must be provided to subsequent calls until it has been fully consumed, except in the case of an intervening call to AudioSink.flush() (or to AudioSink.configure(Format, int, int[]) that causes the sink to be flushed).
    
    Specified by:
    
    handleBuffer in interface AudioSink
    
    Overrides:
    
    handleBuffer in class ForwardingAudioSink
    
    Parameters:
    
    buffer - The buffer containing audio data.
    
    presentationTimeUs - The presentation timestamp of the buffer in microseconds.
    
    encodedAccessUnitCount - The number of encoded access units in the buffer, or 1 if the buffer contains PCM audio. This allows batching multiple encoded access units in one buffer.
    
    Returns:
    
    Whether the buffer was handled fully.
    
    Throws:
    
    AudioSink.InitializationException - If an error occurs initializing the sink.
    
    AudioSink.WriteException - If an error occurs writing the audio data.
  - flush
```
public void flush()
```
    Description copied from interface: AudioSink
    
    Flushes the sink, after which it is ready to receive buffers from a new playback position.
    The audio session may remain active until AudioSink.reset() is called.
    
    Specified by:
    
    flush in interface AudioSink
    
    Overrides:
    
    flush in class ForwardingAudioSink
  - reset
```
public void reset()
```
    Description copied from interface: AudioSink
    
    Resets the sink, releasing any resources that it currently holds.
    
    Specified by:
    
    reset in interface AudioSink
    
    Overrides:
    
    reset in class ForwardingAudioSink
  - dump
```
public void dump(Dumper dumper)
```
    Description copied from interface: Dumper.Dumpable
    
    Dumps the fields of the object using the dumper.
    
    Specified by:
    
    dump in interface Dumper.Dumpable
    
    Parameters:
    
    dumper - The Dumper to be used to dump fields.
