Method Details

read

public int read()
         throws IOException

Description copied from class: java.io.InputStream

Reads the next byte of data from the input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.

A subclass must provide an implementation of this method.

Specified by:

read in class InputStream

Returns:

the next byte of data, or -1 if the end of the stream is reached.

Throws:

IOException - if an I/O error occurs.

disposeStream

public void disposeStream()
                   throws IOException

Actually closes the underlying stream. The close() method does not close the stream so as to allow its reuse.

Throws:

IOException
