Class TeeInputStream

java.lang.Object

java.io.InputStream

org.eclipse.jgit.util.io.TeeInputStream

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class TeeInputStream
extends java.io.InputStream

Input stream that copies data read to another output stream. This stream is primarily useful with a TemporaryBuffer, where any data read or skipped by the caller is also duplicated into the temporary buffer. Later the temporary buffer can then be used instead of the original source stream. During close this stream copies any remaining data from the source stream into the destination stream.
