java.io.InputStream

Synopsis

This abstract class is identical to the J2SE InputStream class. All input streams must extend this class. Applications that define a subclass of InputStream must always implement the abstract read() method, which reads in a single byte of data or -1 if there is no more data to be read. Other important methods include available(), which returns the number of available bytes that can be read without blocking, as well as skip(), which skips over the specified number of bytes. Finally, close() will close the input stream, releasing any resources associated with it.
