javax.sound.sampled.LineEvent
The LineEvent class encapsulates information that a line sends its listeners whenever the line opens, closes, starts, or stops. Each of these four state changes is represented by a corresponding type of event. A listener receives the event as a parameter to its update method. By querying the event, the listener can learn the type of event, the line responsible for the event, and how much data the line had processed when the event occurred.
Although this class implements Serializable, attempts to serialize a LineEvent object will fail.

->line-eventclj
(->line-event line type position)Constructor.
Constructs a new event of the specified type, originating from the specified line.
line - the source of this event - javax.sound.sampled.Line
type - the event type (OPEN, CLOSE, START, or STOP) - javax.sound.sampled.LineEvent$Type
position - the number of sample frames that the line had already processed when the event occurred, or AudioSystem.NOT_SPECIFIED - long
throws: java.lang.IllegalArgumentException - if line is null.
Constructor. Constructs a new event of the specified type, originating from the specified line. line - the source of this event - `javax.sound.sampled.Line` type - the event type (OPEN, CLOSE, START, or STOP) - `javax.sound.sampled.LineEvent$Type` position - the number of sample frames that the line had already processed when the event occurred, or AudioSystem.NOT_SPECIFIED - `long` throws: java.lang.IllegalArgumentException - if line is null.
get-frame-positionclj
(get-frame-position this)Obtains the position in the line's audio data when the event occurred, expressed in sample frames. For example, if a source line had already played back 14 sample frames at the time it was paused, the pause event would report the line's position as 14. The next frame to be processed would be frame number 14 using zero-based numbering, or 15 using one-based numbering.
Note that this field is relevant only to certain events generated by data lines, such as START and STOP. For events generated by lines that do not count sample frames, and for any other events for which this value is not known, the position value should be AudioSystem.NOT_SPECIFIED.
returns: the line's position as a sample frame number - long

get-lineclj
(get-line this)Obtains the audio line that is the source of this event.
returns: the line responsible for this event - javax.sound.sampled.Line
Obtains the audio line that is the source of this event. returns: the line responsible for this event - `javax.sound.sampled.Line`
get-typeclj
(get-type this)Obtains the event's type.
returns: this event's type (LineEvent.Type.OPEN, LineEvent.Type.CLOSE,
LineEvent.Type.START, or LineEvent.Type.STOP) - javax.sound.sampled.LineEvent$Type
Obtains the event's type. returns: this event's type (LineEvent.Type.OPEN, LineEvent.Type.CLOSE, LineEvent.Type.START, or LineEvent.Type.STOP) - `javax.sound.sampled.LineEvent$Type`
to-stringclj
(to-string this)Obtains a string representation of the event. The contents of the string may vary between implementations of Java Sound.
returns: a string describing the event. - java.lang.String
