org.apache.hadoop.io.OutputBuffer

A reusable {@link OutputStream} implementation that writes to an in-memorybuffer.

This saves memory over creating a new OutputStream and ByteArrayOutputStream each time data is written.

Typical usage is something like the following:

 OutputBuffer buffer = new OutputBuffer(); while (... loop condition ...) { buffer.reset(); ... write buffer using OutputStream methods ... byte[] data = buffer.getData(); int dataLength = buffer.getLength(); ... write data to its ultimate destination ... }

@see DataOutputBuffer @see InputBuffer

            throw new IllegalArgumentException("path must not be null"); //$NON-NLS-1$
        }
        String result;
        InputStream input = new FileInputStream(path);
        try {
            OutputBuffer ob = new OutputBuffer();
            byte[] buf = new byte[256];
            while (true) {
                int read = input.read(buf);
                if (read < 0) {
                    break;
                }
                ob.write(buf, 0, read);
            }
            result = new String(ob.getData(), 0, ob.getLength(), ENCODING);
            ob.close();
        } finally {
            input.close();
        }
        File file = new File(result);
        return file;
