java.io.InputStream

org.apache.manifoldcf.connectorcommon.fuzzyml.PrefixedInputStream

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class PrefixedInputStream
extends java.io.InputStream

This class represents an input stream that begins with bytes passed to it through the constructor, and then continues with the bytes from a wrapped input stream. It's basically used when we've read past where we want to be in an input stream and need to back up.
