List of prefetch() Examples

Examples of prefetch()

javax.media.Controller.prefetch()
javax.media.bean.playerbean.MediaPlayer.prefetch()
org.apache.sis.internal.storage.ChannelDataInput.prefetch()
Tries to read more bytes from the channel without changing the buffer position. This method returns a negative number if the buffer is already full or if the channel reached the end of stream. Otherwise this method reads an arbitrary amount of bytes not greater than the space available in the buffer, and returns the amount bytes actually read. @return The number of bytes read, or -2 if the buffer is full, or -1 on end of stream. @throws IOException If an error occurred while reading the bytes. @since 0.4
org.geotools.coverage.grid.GridCoverage2D.prefetch()
Hints that the given area may be needed in the near future. Some implementations may spawn a thread or threads to compute the tiles while others may ignore the hint. @param area A rectangle indicating which geographic area to prefetch.This area's coordinates must be expressed according the grid coverage's coordinate reference system, as given by {@link #getCoordinateReferenceSystem}.

Examples of javax.media.Controller.prefetch()

        resetControllerError();


        //  Prefetch each managed Controller
        for(int i = 0; i < controllers.size(); i++) {
            Controller c = (Controller)controllers.elementAt(i);
            c.prefetch();
        }
        
        //  Prefetch this Player.  If it fails, then assume a
        //  ControllerErrorEvent was posted and return false.

             * an ImageInputStream was available. In such case, the ByteBuffer can only be the one created
             * by the above createByteBuffer() method, which is known to be backed by a writable array.
