/** \brief A RTTI (Runtime Type Information) class
|
||||
|
||||
This class implements an RTTI object returned by the
|
||||
RTTI interface below (DECLARE_RTTI).
|
||||
It supports retrieving a classname, the parent type information
|
||||
and comparing two types for equality or collating order.
|
||||
Drawback: No multiple inheritance supported!
|
||||
|
||||
To implement it into your own classes, use the supported RTTI
|
||||
macros.
|
||||
|
||||
\code
|
||||
class MyClass {
|
||||
DECLARE_RTTI;
|
||||
...
|
||||
public:
|
||||
MyClass();
|
||||
...
|
||||
};
|
||||
\endcode
|
||||
|
||||
To implement the RTTI interface, another macro is to be used. There are
|
||||
two versions. One version to implement the RTTI interface for the root type
|
||||
and another version for derived types.
|
||||
\code
|
||||
IMPLEMENT_ROOT_RTTI(MyClass, MyClassNameWithRespectToMyRTTI);
|
||||
\endcode
|
||||
|
||||
and
|
||||
|
||||
\code
|
||||
IMPLEMENT_RTTI(MyDerivedClass, MyDerivedClassNameWithRespectToMyRTTI, MyClass);
|
||||
\endcode
