    • setLogging

      public static Level setLogging(Level level)
      Control the logging level for this class. Since the generated logs at debug level can become huge, this gives a way for external code to provide granular control over the logging.
      Parameters:
      level -
      Returns:
      prior level

    • walkSchema

      public void walkSchema(SchemaElement schema, SchemaVisitor visitor)
      Walk entire schema model.
      Parameters:
      schema - root element of schema to be traversed
      visitor - target visitor for element notifications

    • walkElement

      public void walkElement(SchemaBase root, SchemaVisitor visitor)
      Walk schema model element tree. This recursively traverses the schema model tree rooted in the supplied element, including the element itself, notifying the visitor of each element visited during the traversal.
      Parameters:
      root - node of tree to be toured
      visitor - target visitor for element notifications

    • walkChildren

      public void walkChildren(SchemaBase root, SchemaVisitor visitor)
      Walk the descendants of a root element. This recursively traverses the schema model tree rooted in the supplied element, excluding the element itself, notifying the visitor of each element visited during the traversal.
      Parameters:
      root - node of tree to be toured
      visitor - target visitor for element notifications
