public QDecoderStream(java.io.InputStream in)

Create a Q-decoder that decodes the specified input stream.

Parameters:

in - the input stream

Method Detail

read

public int read()
         throws java.io.IOException

Read the next decoded byte from this input stream. The 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.

Overrides:

read in class QPDecoderStream

Returns:

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

Throws:

java.io.IOException - if an I/O error occurs.
