Class InputStreamWrapper

java.lang.Object
  org.marketcetera.util.file.InputStreamWrapper

All Implemented Interfaces:

Closeable

public class InputStreamWrapper
extends Object
implements Closeable

A wrapped input stream. It may wrap a regular file, the standard input stream, or any other InputStream instance. This wrapper is intended to wrap InputStream instances for use with CloseableRegistry, hence such instances should not be closed directly, that is, without going through the wrapper's close() method.

Since:

0.5.0

InputStreamWrapper

public InputStreamWrapper(InputStream stream,
                          boolean skipClose)

Parameters:

stream - The stream.

skipClose - True if the underlying stream should not be closed.

InputStreamWrapper

public InputStreamWrapper(InputStream stream)
