make_edges function template¶
Note
To enable this feature, define the TBB_PREVIEW_FLOW_GRAPH_FEATURES macro to 1.
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¶
#include <oneapi/tbb/flow_graph.h>
Syntax¶
// 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);
Example¶
The example implements the graph structure in the picture below.
#define TBB_PREVIEW_FLOW_GRAPH_FEATURES 1
#include <oneapi/tbb/flow_graph.h>
int main() {
using namespace oneapi::tbb::flow;
graph g;
broadcast_node<int> input(g);
function_node doubler(g, unlimited, [](const int& i) { return 2 * i; });
function_node squarer(g, unlimited, [](const int& i) { return i * i; });
function_node cuber(g, unlimited, [](const int& i) { return i * i * i; });
buffer_node<int> buffer(g);
auto handlers = make_node_set(doubler, squarer, cuber);
make_edges(input, handlers);
make_edges(handlers, buffer);
for (int i = 1; i <= 10; ++i) {
input.try_put(i);
}
g.wait_for_all();
}
