Public Member Functions
	access ()

void	set_range (const range_t &range)
	Set the range of the current domain. This range is the same among all the processes and is used to compute the keys for each particles.

template<class... S, class = std::enable_if_t<Write>>
entity_t *	make_entity (S &&... args)
	Construct a new entity. The entity's constructor should not be called directly.

void	generate_keys ()
	Make the keys for all the enities present in the tree.

void	sort_entities ()
	Sort the entities present in the tree.

node_t *	root ()

template<class... S, class = std::enable_if_t<Write>>
entity_t *	make_tree_entity (S &&... args)
	Construct a new tree entity. The tree entity's constructor should not be called directly.

void	build_tree ()
	Build the tree topology in the node_map_, insert all the local particles of the tree in a serial way.

void	insert (entity_t &ent)
	Insert a particle in the tree. Search for the nearest parent and refine if necessary.

entity_t &	get (const entity_id_t &id)
	get an entity from the storage

node_t *	find_parent (key_t key)
	Find the closest parent of a key.

void	cofm (node_t *b=nullptr, bool local=false)
	Compute the cofm data for the tree using double stack.

void	update_COM (node_t *b, bool=false)
	Compute the COFM information for a dedicated branch.

void	graphviz (int num)
	Output the tree topology in a file The format is graphviz and can be converted to PDF with dot dot -Tpng file.gv > file.png.

template<typename POLICY_TYPE >

template<std::size_t Priv>

node_t* flecsi::topo::ntree< POLICY_TYPE >::access< Priv >::root ( )

inline

Return the root from the hash table
