'could not deduce template argument'

[Guest mantragora]

Hey Orbolts

So I wanted to iterate over groups but I don't want to use "GA_FOR_ALL_PRIMGROUPS". Other possibility is to use iterators in for{} loop. Code below is straight ctrl+C/ctrl+V from HDK documentation. And it gives me error you can see in attached image.

for (GA_GroupTable::iterator<GA_ElementGroup> it = gdp->primitiveGroups().begin(); !it.atEnd(); ++it) 
{
    // TODO: write your code
}

At first I thought that some #includes are missing but after whole day messing around it I'm out of ideas what is wrong.

My icludes:

#include <UT/UT_DSOVersion.h>
#include <UT/UT_Interrupt.h>
#include <GU/GU_Detail.h>
#include <PRM/PRM_Include.h>
#include <PRM/PRM_ChoiceList.h>
#include <OP/OP_Operator.h>
#include <OP/OP_OperatorTable.h>
#include <GA/GA_ElementGroup.h>
#include <GA/GA_ElementGroupTable.h>
#include <ostream>
#include <functional>
#include <algorithm>
#include <string>
#include <vector>
#include <iostream>

Any ideas ?

Thanks.

I don't see any GA_ElementGroupTable::begin() method. Perhaps try beginTraverse().

Actually there is but it's not a public method. I didn't checked this because I assumed that "Iterating Over Groups" example in help is correct. BeginTraverse() did the trick.

Thank you.

The interface probably changed after the docs was written. It would really help if you guys could log documentation bugs to have it fixed.
