Fields Summary
public static final Class[]	STANDARD_INPUT_TYPE The STANDARD_INPUT_TYPE contains ImageInputStream.class.
protected Class[]	inputTypes The input types.
protected String[]	writerSpiNames The writer SPI names.

Constructors Summary

Methods Summary
public abstract boolean	canDecodeInput(java.lang.Object source) Returns true if the format of source object is supported by this reader. param source the source object to be decoded (for example an ImageInputStream). return true, if the format of source object is supported by this reader, false otherwise. throws IOException if an I/O exception has occurred.
public javax.imageio.ImageReader	createReaderInstance() Returns an instance of the ImageReader implementation for this service provider. return the ImageReader. throws IOException if an I/O exception has occurred. return createReaderInstance(null);
public abstract javax.imageio.ImageReader	createReaderInstance(java.lang.Object extension) Returns an instance of the ImageReader implementation for this service provider. param extension the a plug-in specific extension object, or null. return the ImageReader. throws IOException if an I/O exception has occurred.
public java.lang.String[]	getImageWriterSpiNames() Gets an array of strings with names of the ImageWriterSpi classes that support the internal metadata representation used by the ImageReader of this service provider, or null if there are no such ImageWriters. return the array of strings with names of the ImageWriterSpi classes. throw new UnsupportedOperationException("Not supported yet");
public java.lang.Class[]	getInputTypes() Gets an array of Class objects whose types can be used as input for this reader. return the input types. return inputTypes;
public boolean	isOwnReader(javax.imageio.ImageReader reader) Checks whether or not the specified ImageReader object is an instance of the ImageReader associated with this service provider or not. param reader the ImageReader. return true, if the specified ImageReader object is an instance of the ImageReader associated with this service provider, false otherwise. throw new UnsupportedOperationException("Not supported yet");
