Class ThreadMixer

java.lang.Object
  jass.engine.Out
      jass.engine.ThreadMixer

All Implemented Interfaces:

Sink, Source

public final class ThreadMixer
extends Out
implements Sink

Mixer that runs a thread on each input. Add sources, then call init() method, then you can use it as a normal mixer. Unlike other UG's you can't add or remove sources while running.

Constructor Detail

ThreadMixer

public ThreadMixer(int bufferSize)

Method Detail

signalDone

public void signalDone()

setGain

public void setGain(int k,
                    float g)

Set input gain control vector.

Parameters:

k - index of gain

gains - input gain

getGains

public float[] getGains()

Get input gain control vector.

Parameters:

gains - input gains

addSource

public java.lang.Object addSource(Source s)
                           throws SinkIsFullException

add source to Sink.

Specified by:

addSource in interface Sink

Parameters:

s - Source to add.

Returns:

object representing Source in Sink (may be null).

Throws:

SinkIsFullException

removeSource

public void removeSource(Source s)

Description copied from interface: Sink

Remove a Source

Specified by:

removeSource in interface Sink

Parameters:

s - Source to remove

getSources

public Source[] getSources()

Get array of sources.

Specified by:

getSources in interface Sink

Returns:

array of the Sources, null if there are none.

init

public void init()

getBuffer

public final float[] getBuffer(long t)
                        throws BufferNotAvailableException

Get buffer with frame index t. Return old buffer if have it in cache. Compute next buffer and advance time if requested, throw exception if requested buffer lies in the past or future. This method will be called "behind the scenes" when processing filtergraphs.

Specified by:

getBuffer in interface Source

Overrides:

getBuffer in class Out

Parameters:

t - timestamp of buffer = frame index.

Throws:

BufferNotAvailableException

resetTime

public void resetTime(long t)

Reset time of self and all inputs

Overrides:

resetTime in class Out

Parameters:

t - time to reset to. Patch must be in a state s.t. none of the current times == t

computeBuffer

protected final void computeBuffer()

Compute the next buffer and store in member float[] buf.

Specified by:

computeBuffer in class Out
