Class MutableByteArrayOutputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable
    public final class MutableByteArrayOutputStream
extends java.io.ByteArrayOutputStream
    This class doesn't work yet, but is here to show the idea of a ByteArrayOutputStream where you can track how many bytes you've already written, and go back and write over a previous part of the stream
