Class ProtectedJarOutputStream

java.lang.Object
  extended by java.io.OutputStream
      extended by java.io.FilterOutputStream
          extended by java.util.zip.DeflaterOutputStream
              extended by java.util.zip.ZipOutputStream
                  extended by java.util.jar.JarOutputStream
                      extended by sofya.base.ProtectedJarOutputStream
All Implemented Interfaces:
java.io.Closeable, java.io.Flushable
public class ProtectedJarOutputStream
extends java.util.jar.JarOutputStream

Specialized JarOutputStream which disables the close() method.

Using this class protects a JarOutputStream from being arbitrarily closed when an external method is called to write data to the stream. The closeStream method may be used instead to close the stream. Specifically, this class is used to protect a JarOutputStream from closure by the dump method of the BCEL JavaClass class.
