For more information on service 0N/A * provider interfaces, see the class comment for the 0N/A * <code>IIORegistry</code> class. 0N/A * <p> This interface allows arbitrary objects to be "wrapped" by 0N/A * instances of <code>ImageOutputStream</code>. For example, a 0N/A * particular <code>ImageOutputStreamSpi</code> might allow a generic 0N/A * <code>OutputStream</code> to be used as a destination; another 0N/A * might output to a <code>File</code> or to a device such as a serial 0N/A * <p> By treating the creation of <code>ImageOutputStream</code>s as 0N/A * a pluggable service, it becomes possible to handle future output 0N/A * destinations without changing the API. Also, high-performance 0N/A * implementations of <code>ImageOutputStream</code> (for example, 0N/A * native implementations for a particular platform) can be installed 0N/A * and used transparently by applications. 0N/A * @see javax.imageio.stream.ImageOutputStream 0N/A * A <code>Class</code> object indicating the legal object type 0N/A * for use by the <code>createInputStreamInstance</code> method. 0N/A * Constructs a blank <code>ImageOutputStreamSpi</code>. It is up 0N/A * to the subclass to initialize instance variables and/or 0N/A * override method implementations in order to provide working 0N/A * versions of all methods. 0N/A * Constructs an <code>ImageOutputStreamSpi</code> with a given 0N/A * @param vendorName the vendor name. 0N/A * @param version a version identifier. 0N/A * @param outputClass a <code>Class</code> object indicating the 0N/A * legal object type for use by the 0N/A * <code>createOutputStreamInstance</code> method. 0N/A * @exception IllegalArgumentException if <code>vendorName</code> 0N/A * is <code>null</code>. 0N/A * @exception IllegalArgumentException if <code>version</code> 0N/A * is <code>null</code>. 0N/A * Returns a <code>Class</code> object representing the class or 0N/A * interface type that must be implemented by an output 0N/A * destination in order to be "wrapped" in an 0N/A * <code>ImageOutputStream</code> via the 0N/A * <code>createOutputStreamInstance</code> method. 0N/A * <p> Typical return values might include 0N/A * <code>OutputStream.class</code> or <code>File.class</code>, but 0N/A * any class may be used. 0N/A * @return a <code>Class</code> variable. 0N/A * @see #createOutputStreamInstance(Object, boolean, File) 0N/A * Returns <code>true</code> if the <code>ImageOutputStream</code> 0N/A * implementation associated with this service provider can 0N/A * optionally make use of a cache <code>File</code> for improved 0N/A * performance and/or memory footrprint.

If the 0N/A * use of a cache file is optional, the <code>useCache</code> 0N/A * parameter will be consulted.
