◆ stbox_index_leaf_consistent()

bool stbox_index_leaf_consistent	(	const STBox *	key,
		const STBox *	query,
		StrategyNumber	strategy
	)

Basic routines for indexing temporal numbers.

Since spatiotemporal boxes do not distinguish between inclusive and exclusive bounds it is necessary to generalize the tests, e.g.,

before : (box1->tmax < box2->tmin) => (box1->tmax <= box2->tmin) e.g., to take into account before([a,b],(b,c])
after : (box1->tmin > box2->tmax) => (box1->tmin >= box2->tmax) e.g., to take into account after((b,c],[a,b])
Parameters

[in] key Element in the index

[in] query Value being looked up in the index

[in] strategy Operator of the operator class being applied

Note
This function is used for both GiST and SP-GiST indexes
