Detailed Description

template<typename... Children>
class Dune::TypeTree::CompositeNode< Children >

Base class for composite nodes based on variadic templates.

Constructor & Destructor Documentation

CompositeNode()

template<typename... Children>

Dune::TypeTree::CompositeNode< Children >::CompositeNode ( )

inlineprotected

Default constructor.

This constructor requires the storage type to be default constructible.

Warning

If the storage type is a pointer, the resulting object will not be usable before its children are set using any of the setChild(...) methods!

Member Function Documentation

child() [1/4]

template<typename... Children>

template<std::size_t k>

Child< k >::Type & Dune::TypeTree::CompositeNode< Children >::child ( index_constant< k >  = {} )

inline

Returns the k-th child.

Returns

a reference to the k-th child.

child() [2/4]

template<typename... Children>

template<std::size_t k>

const Child< k >::Type & Dune::TypeTree::CompositeNode< Children >::child ( index_constant< k >  = {} ) const

inline

Returns the k-th child (const version).

Returns

a const reference to the k-th child.

child() [3/4]

template<typename... Children>

template<typename... Indices>

ImplementationDefined & Dune::TypeTree::CompositeNode< Children >::child ( Indices...  indices )

inline

Returns the child given by the list of indices.
