Example 2 with PointValue

use of org.neo4j.values.storable.PointValue in project neo4j by neo4j.

the class GenericAccessorPointsTest method shouldNotGetRoundingErrorsWithPointsJustWithinTheTileUpperBound.

 * The test mustHandlePointArraysWithinSameTile was flaky on random numbers that placed points just
 * within the tile upper bound, and allocated points to adjacent tiles due to rounding errors.
 * This test uses a specific point that triggers that exact failure in a non-flaky way.
