A line is an element of the digital audio * "pipeline," such as a mixer, an input or output port, * or a data path into or out of a mixer. * <p> * A line can have controls, such as gain, pan, and reverb. * The controls themselves are instances of classes that extend the * base <code>{@link Control}</code> class. * The <code>Line</code> interface provides two accessor methods for * obtaining the line's controls: <code>{@link #getControls getControls}</code> returns the * entire set, and <code>{@link #getControl getControl}</code> returns a single control of * specified type. * <p> * Lines exist in various states at different times. When a line opens, it reserves system * resources for itself, and when it closes, these resources are freed for * other objects or applications. The <code>{@link #isOpen()}</code> method lets * you discover whether a line is open or closed. * An open line need not be processing data, however. Such processing is * typically initiated by subinterface methods such as * <code>{@link SourceDataLine#write SourceDataLine.write}</code> and * <code>{@link TargetDataLine#read TargetDataLine.read}</code>. *<p> * You can register an object to receive notifications whenever the line's * state changes. The object must implement the <code>{@link LineListener}</code> * interface, which consists of the single method * <code>{@link LineListener#update update}</code>. * This method will be invoked when a line opens and closes (and, if it's a * {@link DataLine}, when it starts and stops). *<p> * An object can be registered to listen to multiple lines. The event it * receives in its <code>update</code> method will specify which line created * the event, what type of event it was * (<code>OPEN</code>, <code>CLOSE</code>, <code>START</code>, or <code>STOP</code>), * and how many sample frames the line had processed at the time the event occurred. * <p> * Certain line operations, such as open and close, can generate security * exceptions if invoked by unprivileged code when the line is a shared audio * resource. * * @author Kara Kytle * * @see LineEvent * @since 1.3 */ public interface Line extends AutoCloseable { /** * Obtains the <code>Line.Info</code> object describing this * line. * @return description of the line */ public Line.Info getLineInfo(); /** * Opens the line, indicating that it should acquire any required * system resources and become operational. * If this operation * succeeds, the line is marked as open, and an <code>OPEN</code> event is dispatched * to the line's listeners. * <p> * Note that some lines, once closed, cannot be reopened. Attempts * to reopen such a line will always result in an <code>LineUnavailableException</code>. * <p> * Some types of lines have configurable properties that may affect * resource allocation. For example, a <code>DataLine</code> must * be opened with a particular format and buffer size. Such lines * should provide a mechanism for configuring these properties, such * as an additional <code>open</code> method or methods which allow * an application to specify the desired settings. * <p> * This method takes no arguments, and opens the line with the current * settings. For <code>{@link SourceDataLine}</code> and * <code>{@link TargetDataLine}</code> objects, this means that the line is * opened with default settings. For a <code>{@link Clip}</code>, however, * the buffer size is determined when data is loaded. Since this method does not * allow the application to specify any data to load, an IllegalArgumentException * is thrown. Therefore, you should instead use one of the <code>open</code> methods * provided in the <code>Clip</code> interface to load data into the <code>Clip</code>. * <p> * For <code>DataLine</code>'s, if the <code>DataLine.Info</code> * object which was used to retrieve the line, specifies at least * one fully qualified audio format, the last one will be used * as the default format. * * @throws IllegalArgumentException if this method is called on a Clip instance. * @throws LineUnavailableException if the line cannot be * opened due to resource restrictions. * @throws SecurityException if the line cannot be * opened due to security restrictions. * * @see #close * @see #isOpen * @see LineEvent * @see DataLine * @see Clip#open(AudioFormat, byte[], int, int) * @see Clip#open(AudioInputStream) */ public void open() throws LineUnavailableException; /** * Closes the line, indicating that any system resources * in use by the line can be released.
