org.luaj.vm2.Buffer

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

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

Typical usage is something like the following:

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