Interface DataLine
- AutoCloseable, Line
- Clip, SourceDataLine, TargetDataLine
- GstDataLine, GstSourceDataLine
The DataLine interface adds data-related functionality to the Line
interface. For example, it adds methods to start and stop the data
on the line.
class | DataLine.Info- This class extends Line.Info with information specific to DataLine.
|
int | available()- Return the number of bytes currently available on this DataLine.
|
void | drain()- This method blocks until whatever data is buffered in the
DataLine's internal buffer has been drained.
|
void | flush()- This flushes the DataLine by discarding any buffered data.
|
int | getBufferSize()- Returns the size of the DataLine's internal buffer, in bytes.
|
AudioFormat | getFormat()- Return the current format of the data associated with this DataLine.
|
int | getFramePosition()- Return the current frame position.
|
float | getLevel()- Return the volume level for this DataLine.
|
long | getLongFramePosition()- Return the current frame position.
|
long | getMicrosecondPosition()- Return the number of microseconds this DataLine has been playing.
|
boolean | isActive()- Return true if this line is active, meaning that it is actively
performing audio I/O.
|
boolean | isRunning()- Return true if this line is running, meaning that it has been
started.
|
void | start()- Start processing data.
|
void | stop()- Stop processing data.
