\brief Base class for visitors to IpeObject.
45
Many operations on Ipe objects are implemented as visitors, all
46
derived from IpeVisitor.
48
The default implementation of each VisitXXX member calls
49
VisitObject. The default implementation of VisitObject doesn't do
53
//! Pure virtual destructor.
54
IpeVisitor::~IpeVisitor()
59
//! Called on an IpeGroup object.
60
void IpeVisitor::VisitGroup(const IpeGroup *obj)
65
//! Called on an IpePath object.
66
void IpeVisitor::VisitPath(const IpePath *obj)
71
//! Called on an IpeMark object.
72
void IpeVisitor::VisitMark(const IpeMark * obj)
77
//! Called on an IpeImage object.
78
void IpeVisitor::VisitImage(const IpeImage * obj)
83
//! Called on an IpeText object.
84
void IpeVisitor::VisitText(const IpeText * obj)
89
//! Called on an IpeReference object.
90
void IpeVisitor::VisitReference(const IpeReference * obj)
95
//! Called on an IpeObject.
96
/*! This is called if the more specific function is not implemented by

void IpeVisitor::VisitObject(const IpeObject *)
