Detailed Description

RTTI Different methods for runtime type identification.

Function Documentation

template<typename T, typename U>
T* BNPP::RTTI::castTo ( const U * u )

Cast an object to a specialized class.

Example:

          Composite* composite = ...;
          ...
          
          // check whether the composite is also an atom
          if (RTTI::isKindOf<Atom>(composite))
          {
          // perform some atom specific actions
          Atom* atom = RTTI::castTo<Atom>(*composite);
          ...
          atom->setCharge(0);
          ...
          }
template<typename T>
void* BNPP::RTTI::getNew ( )

Return a void pointer to a new instance of the class.

Use this method to provide an easy factory for objects of a certain class. The main use of this function lies in object persistence. The Serializer needs a function for the dynamic creation of objects.
template<typename T, typename U>
bool BNPP::RTTI::isInstanceOf ( const U & u )

Return { true} if a given object is an instance of a given class.

If { u} is an instance of { T}, this predicate returns { true}. If { u} is an instance of a class that is derived from { T} or a base class of { T}, it returns false.
template<typename T, typename U>
bool BNPP::RTTI::isKindOf ( const U & u )

Return true if u is a kind of T.

If u is an instance of a class derived from T, this predicate returns true:

          Protein p;
          
          // return true, since Protein is derived from Participant
          bool is_participant = RTTI::isKindOf<Participant>(p);
template<typename T, typename U>
bool BNPP::RTTI::isPointerKindOf ( const U * u )

Return true if u is a kind of T.

If u is an instance of a class derived from T, this predicate returns true:

          Protein* p = new Protein();
          
          // return true, since Protein is derived from Participant
          bool is_participant = RTTI::isPointerKindOf<Participant>(p);
