Constructor Detail

TimestampLimitedSignalSource

public TimestampLimitedSignalSource(SignalSource<T> signalSource,
                                    long maxTimestampInMS)

Creates a timestamp limited signal source.

Parameters:

signalSource - signal source to read from

maxTimestampInMS - max timestamp up to which to read in ms

TimestampLimitedSignalSource

public TimestampLimitedSignalSource(SignalSource<T> signalSource,
                                    long maxTimestamp,
                                    TimeUnit timeUnit)

Creates a timestamp limited signal source.

Parameters:

signalSource - signal source to read from

timeUnit - time unit for the timestamp

maxTimestamp - max timestamp up to which to read

Method Detail

getMaxTimestamp

public long getMaxTimestamp(TimeUnit timeUnit)

Max timestamp up to which to read.

Parameters:

timeUnit - desired unit

Returns:

timestamp in ms

getSignalSource

public SignalSource<T> getSignalSource()

Warpped signal source.

Returns:

signal source

read

public T read()
       throws IOException

Description copied from interface: SignalSource

Provide the next chunk of output data. This method is called by a consumer of SignalSource data, typically an SignalPullProcessor.

Specified by:

read in interface SignalSource<T extends AudioBuffer>

Returns:

output data - perhaps a float[] or even a more complex object like a AudioBuffer, null if no more data is available

Throws:

IOException - if something goes wrong

reset

public void reset()

Description copied from interface: SignalSource

Reset the internal state of this AudioGenerator. Implementing methods must call the source's SignalSource.reset() method.

Specified by:

reset in interface SignalSource<T extends AudioBuffer>

close

public void close()
           throws IOException

Closes the underlying SignalSource, if it implements Closeable.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Throws:

IOException

toString

public String toString()

Overrides:

toString in class Object
