template<typename T>
void | tbb::flow::interface6::make_edge (sender< T > &p, receiver< T > &s)
| Makes an edge between a single predecessor and a single successor.

## Detailed Description

The graph related classes and functions.

There are some applications that best express dependencies as messages passed between nodes in a graph. These messages may contain data or simply act as signals that a predecessors has completed. The graph class and its associated node classes can be used to express such applcations.
