Member Function Documentation

afterChild()

template<typename T1, typename Child1, typename T2, typename Child2, typename TreePath, typename ChildIndex>

void Dune::TypeTree::DefaultPairVisitor::afterChild ( T1 && , Child1 && , T2 && , Child2 && , TreePath , ChildIndex  ) const

inlineinherited

Method for child-parent traversal.

This method gets called after visiting a child node.

Note

This method gets called even if the visitor decides not to visit the child in question.

Parameters

t1	The node of the first tree to visit.
child1	The child of t1 to visit.
t2	The node of the second tree to visit.
child2	The child of t2 to visit.
treePath	The position of the parent nodes within the TypeTree.
childIndex	The index of the child nodes in relation to the parent nodes.

beforeChild()

template<typename T1, typename Child1, typename T2, typename Child2, typename TreePath, typename ChildIndex>

void Dune::TypeTree::DefaultPairVisitor::beforeChild ( T1 && , Child1 && , T2 && , Child2 && , TreePath , ChildIndex  ) const

inlineinherited

Method for parent-child traversal.

This method gets called before visiting a child node.

Note

This method gets called even if the visitor decides not to visit the child in question.

Parameters

t1	The node of the first tree to visit.
child1	The child of t1 to visit.
t2	The node of the second tree to visit.
child2	The child of t2 to visit.
treePath	The position of the parent nodes within the TypeTree.
childIndex	The index of the child nodes in relation to the parent nodes.

in()

template<typename T1, typename T2, typename TreePath>

void Dune::TypeTree::DefaultPairVisitor::in ( T1 && , T2 && , TreePath  ) const

inlineinherited

Method for infix tree traversal.

This method gets called BETWEEN visits of children of a non-leaf node. That definition implies that this method will only be called for nodes with at least two children.

Parameters

t1	The node of the first tree to visit.
t2	The node of the second tree to visit.
treePath	The position of the node within the TypeTree.

leaf()

template<typename T1, typename T2, typename TreePath>

void Dune::TypeTree::DefaultPairVisitor::leaf ( T1 && , T2 && , TreePath  ) const

inlineinherited

Method for leaf traversal.

This method gets called when encountering a leaf node within the pair of TypeTrees.

Attention

Since the two TypeTrees are not required to be exactly identical, it is only guaranteed that at least one of the nodes is a leaf node, not both.

Parameters

t1	The node of the first tree to visit.
t2	The node of the second tree to visit.
treePath	The position of the node within the TypeTree.

post()

template<typename T1, typename T2, typename TreePath>

void Dune::TypeTree::DefaultPairVisitor::post ( T1 && , T2 && , TreePath  ) const

inlineinherited

Method for postfix traversal.

This method gets called after all children of a non-leaf node have been visited.

Parameters

t1	The node of the first tree to visit.
t2	The node of the second tree to visit.
treePath	The position of the node within the TypeTree.

pre()

template<typename T1, typename T2, typename TreePath>

void Dune::TypeTree::DefaultPairVisitor::pre ( T1 && , T2 && , TreePath  ) const

inlineinherited

Method for prefix tree traversal.

This method gets called when first encountering a non-leaf node and before visiting any of its children.

Parameters

t1	The node of the first tree to visit.
t2	The node of the second tree to visit.
treePath	The position of the node within the TypeTree.
