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

T	The base type
k	The 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!
