Class MutableOutputStream

java.lang.Object

java.io.OutputStream

com.grey.base.utils.MutableOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

public class MutableOutputStream
extends OutputStream

Alternative to BufferedOutputStream, which allows the buffer contents to be manipulated before they are flushed. Unlike BufferedOutputStream, our goal is not simply to minimise writes, but to do so subject to always keeping the most recent buf.length bytes in our buffer.
