- java.lang.Object
- - org.kie.internal.builder.help.KnowledgeBuilderHelper

-     public class KnowledgeBuilderHelper
      extends Object

  Provides helper methods for working with JAXB and a Knowledgebase, it takes care of the Classpath issues when mapping against internal type declarations.

  This api is experimental and thus the classes and the interfaces returned are subject to change.
