Package org.zkoss.util.media

Class RepeatableMedia

  • All Implemented Interfaces:
    java.io.Serializable, Media
    public class RepeatableMedia
extends java.lang.Object
implements Media, java.io.Serializable
    RepeatableMedia adds functionality to another media, the ability to read repeatedly. Unlike other media, RepeatableMedia uses RepeatableInputStream, if binary, or RepeatableReader to make getStreamData() and getReaderData() to be able to re-open when InputStream.close() or Reader.close() is called. In other words, the buffered input stream of the give media is never closed until it is GC-ed.
