Class ClassStreamHandler

  org.apache.wicket.util.io.ClassStreamHandler

public final class ClassStreamHandler
extends Object

TODO DOC ME! NOTE: this class uses Sun-specific features: we use Unsafe because we need to set the final fields, and we use ReflectionFactory to be able to find constructors appropriate for serialization.
