Constructors for Flow Graph nodes

To enable this feature, define the
TBB_PREVIEW_FLOW_GRAPH_FEATURES
macro to 1.

Description

The “Helper Functions for Expressing Graphs” feature adds a set of new constructors that can be used to construct a node that
follows
or
precedes
a set of nodes.
Where possible, the constructors support Class Template Argument Deduction (since C++17).
