preOrderVisit

public static void preOrderVisit(LanguageObjectVisitor behaviorVisitor,
                                 ILanguageObject object)

This utility method can be used to execute the behaviorVisitor in a pre-order walk of the language objects. "Pre-order" in this case means that the visit method of the behaviorVisitor will be called before the visit method of it's children. It is expected that the behavior visit does NOT perform iteration, as that function will be performed by the HierarchyVisitor.

Parameters:

behaviorVisitor - The visitor specifying what behavior is performed at each node type

object - The root of the object tree to perform visitation on

postOrderVisit

public static void postOrderVisit(LanguageObjectVisitor behaviorVisitor,
                                  ILanguageObject object)

This utility method can be used to execute the behaviorVisitor in a post-order walk of the language objects. "Post-order" in this case means that the visit method of the behaviorVisitor will be called after the visit method of it's children. It is expected that the behavior visit does NOT perform iteration, as that function will be performed by the HierarchyVisitor.

Parameters:

behaviorVisitor - The visitor specifying what behavior is performed at each node type

object - The root of the object tree to perform visitation on
