public abstract class AbstractLanguageVisitor
extends java.lang.Object
implements LanguageObjectVisitor

Visitor that visits an instance of ILanguageObject and performs an operation on that instance. The visit() methods of this Visitor can be selectively overridden to perform operations on each type of ILanguageObject. The public visit() methods should not be called directly, as they are only used by this visitor framework to let the instance invoke the type-specific visit() method

Method Detail

visitNode

public void visitNode(LanguageObject obj)

Visit the ILanguageObject instance to perform the Visitor's operation on that instance. This method can also be used by the subclass to visit any ILanguageObject instances that the given instance may contain.

Parameters:

obj - an ILanguageObject instance

HierarchyVisitor

visitNodes

public void visitNodes(java.util.Collection<? extends LanguageObject> nodes)

Visits a Collection of ILanguageObjects in iteration order. This method can be used by subclasses to visit each ILanguageObject in the Collection

Parameters:

nodes - a Collection of ILanguageObjects

visitNodes

public void visitNodes(LanguageObject[] nodes)

Visits an array of ILanguageObjects in order. This method can be used by subclasses to visit each ILanguageObject in the array.

Parameters:

nodes - an ILanguageObject[]
