IsKindOf()

virtual bool CElementMethods::IsKindOf ( const CElementMethods *  methods ) const

virtual

For class we if this->GetBaseType() == B->GetType() that means that this knows how to copy from B.

This is the default object comparison method use when we store raw memory structure If we compare this and B:

• We have this->GetBaseType == B->GetType, we make a memcpy with the size of the structure
• We have this->GetBaseType = B->GetType, we memcpy with the sizeof(A)
• We have this->GetType = B->GetBaseType, we memcpy with the sizeof(B) @Note If we have this->GetBaseType == this->GetBaseType we cannot do anything even if the structure are in relation, because
  we don't know the sizeof the BaseType. In such case IsObject should return true and CopyElement can handle this
  kind copy
  

IsObject()

virtual bool CElementMethods::IsObject ( ) const

virtual

Return false is element array are object that need to be destructed, copied or serialized
in this case, element are memory struct and array used memcpy
when true is returned, DestructElement/CopyElement/SerializeElement is called anytime it is needed
@Note for class should return true if the class has virtual method and if we make copy between inherited object
otherwise memcpy overwrite the virtual table, and the inheritance is lost
