LineEvent JDK 1.6)

Description

public class LineEvent

The LineEvent class encapsulates information that a line sends its listeners whenever the line opens, closes, starts, or stops.

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.
