StreamOutput

public StreamOutput(java.io.OutputStream out,
                    int bufferSize)

Constructs a new instance.

Parameters:

out - the OutputStream object.

bufferSize - the buffer size.

Method Detail

close

public void close()
           throws java.io.IOException

Overrides the Output.close(). Closes this output and releases any system resources associated with the under layer output.

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

flush

public void flush()
           throws java.io.IOException

Overrides the Output.flush(). Flushes this output and forces any buffered output bytes to be written out if the under layer output method support.

Specified by:

Throws:

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

getOut

protected java.io.OutputStream getOut()

Gets the output stream.

Returns:

the output stream.

write

public int write(java.nio.ByteBuffer src)
          throws java.io.IOException

Overrides the Output.write(ByteBuffer). Writes a sequence of bytes to this output from the given buffer.

Specified by:

write in interface Output

Parameters:

src - The buffer from which bytes are to be retrieved.
