Java Source Code / Java Documentation » 6.0 JDK Core » image » javax.imageio.stream   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    javax.imageio.stream.ImageInputStreamImpl       javax.imageio.stream.ImageOutputStreamImpl          javax.imageio.stream.MemoryCacheImageOutputStream MemoryCacheImageOutputStream public class MemoryCacheImageOutputStream extends ImageOutputStreamImpl (Code) An implementation of ImageOutputStream that writes its output to a regular OutputStream. A memory buffer is used to cache at least the data between the discard position and the current write position. The only constructor takes an OutputStream, so this class may not be used for read/modify/write operations. Reading can occur only on parts of the stream that have already been written to the cache and not yet flushed. version:    0.5 Constructor Summary public   MemoryCacheImageOutputStream(OutputStream stream)      Constructs a MemoryCacheImageOutputStream that will write to a given OutputStream. Method Summary public  void close()      Closes this MemoryCacheImageOutputStream. public  void flushBefore(long pos)      public  boolean isCached()      Returns true since this ImageOutputStream caches data in order to allow seeking backwards. public  boolean isCachedFile()      Returns false since this ImageOutputStream does not maintain a file cache. public  boolean isCachedMemory()      Returns true since this ImageOutputStream maintains a main memory cache. public  long length()      public  int read()      public  int read(byte[] b, int off, int len)      public  void write(int b)      public  void write(byte[] b, int off, int len)      Constructor Detail MemoryCacheImageOutputStream public MemoryCacheImageOutputStream(OutputStream stream)(Code) Constructs a MemoryCacheImageOutputStream that will write to a given OutputStream. Parameters:   stream - an OutputStream to write to. exception:   IllegalArgumentException - if stream isnull. Method Detail close public void close() throws IOException(Code) Closes this MemoryCacheImageOutputStream. All pending data is flushed to the output, and the cache is released. The destination OutputStream is not closed. flushBefore public void flushBefore(long pos) throws IOException(Code) isCached public boolean isCached()(Code) Returns true since this ImageOutputStream caches data in order to allow seeking backwards. true. See Also:   MemoryCacheImageOutputStream.isCachedMemory See Also:   MemoryCacheImageOutputStream.isCachedFile isCachedFile public boolean isCachedFile()(Code) Returns false since this ImageOutputStream does not maintain a file cache. false. See Also:   MemoryCacheImageOutputStream.isCached See Also:   MemoryCacheImageOutputStream.isCachedMemory isCachedMemory public boolean isCachedMemory()(Code) Returns true since this ImageOutputStream maintains a main memory cache. true.
