An abstract base class,<code>ImageInputStreamImpl</code> is provided to simplify writinga new <code>ImageInputStream</code> class.  Concrete implementationclasses (<code>FileImageInputStream</code>,<code>FileCacheImageInputStream</code>, and<code>MemoryCacheImageInputStream</code>) are provided that allowinput to come from a <code>File</code> or <code>InputStream</code>with or without the use of a temporary cache file. <p> The <code>ImageOutputStream</code> interface performs an analogousfunction for output.  An abstract base class,<code>ImageOutputStreamImpl</code> is provided, along withconcrete implementation classes (<code>FileImageOutputStream</code>,<code>FileCacheImageOutputStream</code>, and<code>MemoryCacheImageOutputStream</code>) are provided that allowoutput to go to a <code>File</code> or <code>OutputStream</code> withor without the use of a temporary cache file. <p> The <code>IIOByteBuffer</code> class provides an alternative way toperform reads of sequences of bytes that reduces the amount ofinternal data copying. @since 1.4</body></html>
