Detailed Description

template<typename... T>
class Dune::TypeTree::HybridTreePath< T >

A hybrid version of TreePath that supports both compile time and run time indices.

A HybridTreePath supports storing a combination of run time and compile time indices. This makes it possible to store the tree path to a tree node inside the tree node itself, even if the path contains one or more PowerNodes, where each child must have exactly the same type. At the same time, as much information as possible is kept accessible at compile time, allowing for more efficient algorithms.
