Member Function Documentation

virtual Object* VCF::PropertyChangeEvent::clone (  bool  deep = false  )  const [inline, virtual]
 

Makes a complete clone of this object.

A typical implementation might be: 

    virtual Object* clone( bool deep ) {
        return new MyObject( this );
    }
In which the implementer simply creates a new instance on the heap and calls the copy constructor. Objects which support cloning should also have a copy constructor defined as well.

Parameters:
bool deep if deep is true then any object instances that this object owns should probably be cloned as well, with full new copies made. Otherwise it would be acceptable to simply copy the pointer values. The default value is for deep cloning to be false.
Returns:
Object a new instance that should be an copy of this. If the object doesn't support cloning the return will value will be NULL.

Reimplemented from VCF::Event.

VariantData * VCF::PropertyChangeEvent::getChangeValue (   )  [inline]
 

returns the VariantData that represents the new value

VariantData * VCF::PropertyChangeEvent::getOriginalValue (   )  [inline]
 

returns a VariantData that represents the original value before the change

PropertyChangeEvent& VCF::PropertyChangeEvent::operator= (  const PropertyChangeEvent &  rhs  )  [inline]
