Class OverriddenMethodsVisitor

java.lang.Object

edu.umd.cs.findbugs.ba.ch.OverriddenMethodsVisitor

All Implemented Interfaces:

SupertypeTraversalVisitor

Direct Known Subclasses:

AbstractMethodAnnotationAccumulator

public abstract class OverriddenMethodsVisitor
extends java.lang.Object
implements SupertypeTraversalVisitor

This class implements a best-effort visitation of all methods overridden by a given derived instance method. Objects extending this class can be used with the Subtypes2.traverseSupertypes(ClassDescriptor, InheritanceGraphVisitor) method.

Constructor Detail

OverriddenMethodsVisitor

public OverriddenMethodsVisitor(XMethod xmethod)

Constructor.

Parameters:

xmethod - a derived method

Method Detail

getXmethod

public XMethod getXmethod()

Returns:

Returns the xmethod.

visitClass

public boolean visitClass(ClassDescriptor classDescriptor,
                 XClass xclass)

Description copied from interface: SupertypeTraversalVisitor

Visit a class vertex in the inheritance graph. Only called for classes that could be resolved, not called for java.lang.Object.

Specified by:

visitClass in interface SupertypeTraversalVisitor

Parameters:

classDescriptor - ClassDescriptor of the class vertex

xclass - XClass object containing information about the class; never null

Returns:

true if traversal should continue, false otherwise

visitOverriddenMethod

protected abstract boolean visitOverriddenMethod(XMethod xmethod)

Downcall method: will be called for each method overridden by the derived method object passed to the constructor. Note that this method will be called for the original derived method, since this is useful for some applications.

Parameters:

xmethod - a method which is overridden by the original derived method, or is the original derived method

Returns:

true if the traversal should continue into superclasses, false otherwise
