Detailed Description

template<class NODE>
class octomap::OcTreeBase< NODE >::leaf_iterator

Iterator to iterate over all leafs of the tree.

Inner nodes are skipped. See below for example usage. Note that the non-trivial call to tree->end_leafs() should be done only once for efficiency!

 for(OcTreeTYPE::leaf_iterator it = tree->begin_leafs(),
        end=tree->end_leafs(); it!= end; ++it)
 {
   //manipulate node, e.g.:
   std::cout << "Node center: " << it.getCoordinate() << std::endl;
   std::cout << "Node size: " << it.getSize() << std::endl;
   std::cout << "Node value: " << it->getValue() << std::endl;
 }
