Class ObjectInputStreamWithOsgiClassResolution

java.lang.Object
  extended by java.io.InputStream
      extended by java.io.ObjectInputStream
          extended by org.csstudio.ui.util.dnd.ObjectInputStreamWithOsgiClassResolution
All Implemented Interfaces:
java.io.Closeable, java.io.DataInput, java.io.ObjectInput, java.io.ObjectStreamConstants
public class ObjectInputStreamWithOsgiClassResolution
extends java.io.ObjectInputStream

De-serializes java classes looking for the classloaders in the appropriate osgi bundle. Using the normal ObjectInputStream would resolve classes only according to this plugin classloader. This resolves the classes by looking for the class in any plugin whose name is a package parent of the given class.
