Detailed Description

template<typename T, std::size_t k>
class Dune::TypeTree::PowerNode< T, k >

Collect k instances of type T within a dune-typetree.

Template Parameters
TThe base type
kThe number of instances this node should collect

Constructor & Destructor Documentation

◆ PowerNode()

template<typename T , std::size_t k>
Dune::TypeTree::PowerNode< T, k >::PowerNode ( )
inlineprotected

Default constructor.

The default constructor is protected, as PowerNode is a utility class that needs to be filled with meaning by subclassing it and adding useful functionality to the subclass.

Warning
When using the default constructor, make sure to set ALL children by means of the setChild() methods!
