Description

The make_edges function template creates edges between a single node and each node in a set of nodes.

There are two ways to connect nodes in a set and a single node using make_edges:

API

Header

.. code:: cpp

#include <oneapi/tbb/flow_graph.h>

Syntax

.. code:: cpp

// node_set is an exposition-only name for the type returned from make_node_set function

template <typename NodeType, typename Node, typename... Nodes>
void make_edges(node_set<Node, Nodes...>& set, NodeType& node);

template <typename NodeType, typename Node, typename... Nodes>
void make_edges(NodeType& node, node_set<Node, Nodes...>& set);
