◆ tbox_index_leaf_consistent()

bool tbox_index_leaf_consistent	(	const TBox *	key,
		const TBox *	query,
		StrategyNumber	strategy
	)

Basic routines for indexing temporal values.

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

left : (box1->xmax < box2->xmin) => (box1->xmax <= box2->xmin) e.g., to take into account left([a,b],(b,c])
right : (box1->xmin > box2->xmax) => (box1->xmin >= box2->xmax) e.g., to take into account right((b,c],[a,b]) and similarly for before and after
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
