forEachChild()

template<Concept::InnerTreeNode Tree, class Callable >

constexpr void Dune::TypeTree::forEachChild ( Tree &&  container, Callable &&  at_value  )

constexpr

Traverse each child of a tree and apply a callable function.

This function iterates over each child node of a given tree and applies a callable function to each child. The callable function can accept either one or two arguments: the child node itself, and optionally, its index.

Template Parameters

Tree	The type of the tree container to be traversed. This must satisfy the Concept::InnerTreeNode concept.
Callable	The type of the callable function (functor) to be applied to each child node. This can be a lambda, function pointer, or any callable object.

Parameters

container	The tree container whose children will be traversed.
at_value	The callable function to be applied to each child node. This function can accept either one argument (the child node) or two arguments (the child node and its index).

forEachLeafNode()

template<Concept::TreeNode Tree, class LeafFunc >

void Dune::TypeTree::forEachLeafNode	(	Tree &&	tree,
		LeafFunc &&	leafFunc
	)

Traverse tree and visit each leaf node.

The passed callback function is called with the node and corresponding treepath as arguments.

Parameters

tree	The tree to traverse
leafFunc	This function is called for each leaf node

References Dune::TypeTree::forEachNode().

forEachNode() [1/2]

template<Concept::TreeNode Tree, class NodeFunc >

void Dune::TypeTree::forEachNode	(	Tree &&	tree,
		NodeFunc &&	nodeFunc
	)

Traverse tree and visit each node.

The passed callback function is called with the node and corresponding treepath as arguments.

Parameters

tree	The tree to traverse
nodeFunc	This function is called for each node

References Dune::TypeTree::forEachNode().

forEachNode() [2/2]

template<class Tree , class PreNodeFunc , class LeafNodeFunc , class PostNodeFunc >

void Dune::TypeTree::forEachNode	(	Tree &&	tree,
		PreNodeFunc &&	preNodeFunc,
		LeafNodeFunc &&	leafNodeFunc,
		PostNodeFunc &&	postNodeFunc
	)

Traverse tree and visit each node.

This does an in-order traversal of the tree. For leaf node the leafNodeFunc callback is called. For each inner node this function first calls the preNodeFunc, then it traverses the children, and then it calls the postNodeFunc. All callback functions are called with the node and corresponding treepath as arguments.

Parameters

tree	The tree to traverse
preNodeFunc	This function is called for each inner node
leafNodeFunc	This function is called for each leaf node
postNodeFunc	This function is called for each inner node
