◆ hasPredecessor()

		unsigned int	MaxSteps = `0`,
		bool	TopologicalPrune = `false`
	)

inlinestatic

Returns true if N is a predecessor of any node in Worklist.

This helper keeps Visited and Worklist sets externally to allow unions searches to be performed in parallel, caching of results across queries and incremental addition to Worklist. Stops early if N is found but will resume. Remember to clear Visited and Worklists if DAG changes. MaxSteps gives a maximum number of nodes to visit before giving up. The TopologicalPrune flag signals that positive NodeIds are topologically ordered (Operands have strictly smaller node id) and search can be pruned leveraging this.
