template<typename Element >

bool DataModel_detail::CompareAndPrint::operator() ( Element *  f, Element *  s  ) const

inline

Compare two pointers.

Maybe print a complaint if we find a duplicate.

  {
    bool areEq = (f == s); 
    if (!m_quiet && areEq && f != 0)
      warn (typeid (*f), f);
    return areEq;
  }

warn()

void DataModel_detail::CompareAndPrint::warn	(	const std::type_info &	ti,
		const void *	f
	)		const

Duplicate elements were found; print a warning.

Parameters

ti	type_info for the element.
f	The element pointer.
