ImageOutputStreamSpi

• java.lang.Object
  • javax.imageio.spi.IIOServiceProvider

Fields Summary
protected Class	outputClass The output class.

Constructors Summary
protected ImageOutputStreamSpi() Instantiates a new ImageOutputStreamSpi. throw new UnsupportedOperationException("Not supported yet");
public ImageOutputStreamSpi(String vendorName, String version, Class outputClass) Instantiates a new ImageOutputStreamSpi. param vendorName the vendor name. param version the version. param outputClass the output class. super(vendorName, version); this.outputClass = outputClass;

Methods Summary
public boolean	canUseCacheFile() Returns true if the ImageOutputStream can use a cache file. If this method returns false, the value of the useCache parameter of createOutputStreamInstance will be ignored. The default implementation returns false. return true, if the ImageOutputStream can use a cache file, false otherwise. return false; // def
public javax.imageio.stream.ImageOutputStream	createOutputStreamInstance(java.lang.Object output) Creates the ImageOutputStream associated with this service provider. The output object should be an instance of the class returned by getOutputClass method. This method uses the default system directory for the cache file, if it is needed. param output the output Object. return the ImageOutputStream. throws IOException if an I/O exception has occurred. return createOutputStreamInstance(output, true, null);
public abstract javax.imageio.stream.ImageOutputStream	createOutputStreamInstance(java.lang.Object output, boolean useCache, java.io.File cacheDir) Creates the ImageOutputStream associated with this service provider. The output object should be an instance of the class returned by getInputClass method. This method uses the specified directory for the cache file, if the useCache parameter is true. param output the output Object. param useCache the flag indicating if cache file is needed or not. param cacheDir the cache directory. return the ImageOutputStream. throws IOException if an I/O exception has occurred.
public java.lang.Class	getOutputClass() Gets an output Class object that represents the class or interface that must be implemented by an output source. return the output class. return outputClass;
public boolean	needsCacheFile() Returns true if the ImageOutputStream implementation requires the use of a cache file. The default implementation returns false. return true, if the ImageOutputStream implementation requires the use of a cache file, false otherwise. return false; // def
