Class OpenInputStream

java.lang.Object
  java.io.InputStream
      org.shiftone.jrat.inject.process.OpenInputStream

All Implemented Interfaces:

java.io.Closeable

public class OpenInputStream
extends java.io.InputStream

Class OpenInputStream wrapps/proxies to a real InputStream and prevents the caller from closing the underlying input stream. This is useful when reading chunks from a ZipInputStream passing the archive entry inputStreams to code that calls close(). This would typically close the entire ZipInputStream, which would prevent any other archive entries from being read.
