Class MemoryCacheImageOutputStream

  extended by javax.imageio.stream.ImageInputStreamImpl sample code for javax.imageio.stream.ImageInputStreamImpl definition code for javax.imageio.stream.ImageInputStreamImpl 
      extended by javax.imageio.stream.ImageOutputStreamImpl sample code for javax.imageio.stream.ImageOutputStreamImpl definition code for javax.imageio.stream.ImageOutputStreamImpl 
          extended by javax.imageio.stream.MemoryCacheImageOutputStream
All Implemented Interfaces:
DataInput sample code for java.io.DataInput definition code for java.io.DataInput , DataOutput sample code for java.io.DataOutput definition code for java.io.DataOutput , ImageInputStream sample code for javax.imageio.stream.ImageInputStream definition code for javax.imageio.stream.ImageInputStream , ImageOutputStream sample code for javax.imageio.stream.ImageOutputStream definition code for javax.imageio.stream.ImageOutputStream 
public class MemoryCacheImageOutputStream
extends ImageOutputStreamImpl sample code for javax.imageio.stream.ImageOutputStreamImpl definition code for javax.imageio.stream.ImageOutputStreamImpl

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.

Description copied from interface: DataOutput sample code for java.io.DataOutput.write(byte[], int, int) definition code for java.io.DataOutput.write(byte[], int, int)
Writes len bytes from array b, in order, to the output stream. If b is null, a NullPointerException is thrown. If off is negative, or len is negative, or off+len is greater than the length of the array b, then an IndexOutOfBoundsException is thrown. If len is zero, then no bytes are written. Otherwise, the byte b[off] is written first, then b[off+1], and so on; the last byte written is b[off+len-1].

public void flushBefore(long pos)
                 throws IOException sample code for java.io.IOException definition code for java.io.IOException
Description copied from interface: ImageInputStream sample code for javax.imageio.stream.ImageInputStream.flushBefore(long) definition code for javax.imageio.stream.ImageInputStream.flushBefore(long)
Discards the initial portion of the stream prior to the indicated postion. Attempting to seek to an offset within the flushed portion of the stream will result in an IndexOutOfBoundsException.

Calling flushBefore may allow classes implementing this interface to free up resources such as memory or disk space that are being used to store data from the stream.

Parameters:
pos - a long containing the length of the file prefix that may be flushed.
Throws:
IOException sample code for java.io.IOException definition code for java.io.IOException - if an I/O error occurs.
