flapGateBlocks()

bool openswmm::hydstruct::flapGateBlocks	(	const SimulationContext &	ctx,
		int	j,
		int	n1,
		int	n2,
		double	q )

Test reverse flow against the link gate and its donor outfall gate.

Link gate tests q*stored direction<0, preserving authored orientation. Outfall test uses the inflow/donor end. Does not mutate flow, apply hydraulic caps or validate arbitrary indices.

Parameters

[in]	ctx	Borrowed coherent link direction/gate flags and node/outfall subtype data.
[in]	j	Valid global link index.
[in]	n1	Valid current node1 endpoint index when q>0.
[in]	n2	Valid current node2 endpoint index when q<0.
[in]	q	Signed flow/direction indicator; only sign is used, positive node1 to node2.

Returns

True for reverse link-gate flow or flow donated by a gated outfall; false for zero/no applicable gate.
