By obtaining thisĭata from the ImageReader and passing it on to the Metadata (as encoded by IIOMetadata objects) That will understand the internal structure of non-pixel Mechanism may be used to obtain an ImageWriter Specify a corresponding ImageWriter, or if the If the plug-in for this ImageReader does not Returns an ImageWritercorresponding to the given setUseCache public static void setUseCache(boolean useCache).Implementation of the Java runtime enviroment. The exact set of locations searched depends on the Instantiate an instance of each class, which is then placed Loader is then used to load each of these classes and to The contents of the located files indicate the names ofĪctual implementation classes which implement theĪforementioned service provider interfaces the default class
ImageOutputStreamSpi, along the application class Where classname is one of ImageReaderSpi, Which dynamically make new plug-ins available at runtime.ĬlassLoader is used locate JAR files containing Thus this method need only be invoked by sophisticated applications Clients can call this method to prompt a re-scan. Rather than re-scanning the classpath on every invocation of theĪPI, the class path is scanned automatically only on the first Theoretically change, or additional plug-ins may become available. This method is needed because the application class path can Provider instance for each one found with the Loads their service provider classes, and registers a service Scans for plug-ins on the application class path,
