int com.quadcap.io.ConcatInputStream.available (   )  throws IOException
 

Returns the number of bytes that can be read from this input stream without blocking.

The available method of InputStream returns 0.

Returns:
the number of bytes that can be read from this input stream without blocking.
Exceptions:
IOException if an I/O error occurs.

int com.quadcap.io.ConcatInputStream.read (   )  throws IOException
 

Reads the next byte of data from this 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.

Returns:
the next byte of data, or -1 if the end of the stream is reached.
Exceptions:
IOException if an I/O error occurs.
