[Connect U12 C++] XAttributeIter missing?

Hi Jean-Pierre,

Jean-Pierre Hundhausen said:

ElementHandle::XAttributeIter is mentioned

it seems documentation is not correct at this point.

or do I overlook something?

I guess (but based on documentation only) you should use XAttributeCollection to obtain all XAtrtibutes and to iterate them.

With regards,

In v8i ElemHandle::XAttributeIter

As Jan wrote, CONNECT has the XAttributeCollection that you construct from an ElementRef.

XAttributeCollection provides the begin() and end() methods like any of the C++ standard collection classes...

XAttributeCollection attributes (elemRef);
for (auto& entry = attributes.begin(); entry != attributes.end(); ++entry)
{
  ... do something with attribute
}

C++ Standard Collection Classes

Many interfaces in the MicroStationAPI either implement the C++ collection classes or emulate the essential functionality for enumeration.

A good example is the Bentley vector template bvector<>. It is a C++ standard vector template class.

It has certain characteristics that make it safe to use in your apps. when working with MicroStation built-in functions. As far as you — the programmer — are concerned, it behaves just like a std::vector<>.  There's more info in this article.
