Examples of java.io.FilterInputStream

java.io.FilterInputStream
A FilterInputStream contains some other input stream, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality. The class FilterInputStream itself simply overrides all methods of InputStream with versions that pass all requests to the contained input stream. Subclasses of FilterInputStream may further override some of these methods and may also provide additional methods and fields. @author Jonathan Payne @version 1.33, 04/07/06 @since JDK1.0
