/**
* A source data line is a data line to which data may be written. It acts as a
* source to its mixer. An application writes audio bytes to a source data line,
* which handles the buffering of the bytes and delivers them to the mixer. The
* mixer may mix the samples with those from other sources and then deliver the
* mix to a target such as an output port (which may represent an audio output
* device on a sound card).
* <p>
* Note that the naming convention for this interface reflects the relationship
* between the line and its mixer. From the perspective of an application, a
* source data line may act as a target for audio data.
* <p>
* A source data line can be obtained from a mixer by invoking the
* {@link Mixer#getLine getLine} method of {@code Mixer} with an appropriate
* {@link DataLine.Info} object.
* <p>
* The {@code SourceDataLine} interface provides a method for writing audio data
* to the data line's buffer. Applications that play or mix audio should write
* data to the source data line quickly enough to keep the buffer from
* underflowing (emptying), which could cause discontinuities in the audio that
* are perceived as clicks. Applications can use the
* {@link DataLine#available available} method defined in the {@code DataLine}
* interface to determine the amount of data currently queued in the data line's
* buffer. The amount of data which can be written to the buffer without
* blocking is the difference between the buffer size and the amount of queued
* data. If the delivery of audio output stops due to underflow, a
* {@link LineEvent.Type#STOP STOP} event is generated. A
* {@link LineEvent.Type#START START} event is generated when the audio output
* resumes.
