com.spatial4j.core.shape.Rectangle
A rectangle aligned with the axis (i.e. it is not at an angle).
In geospatial contexts, it may cross the international date line (-180 longitude) if {@link #getCrossesDateLine()} however it cannot pass the polesalthough it may span the globe. It spans the globe if the X coordinate (Longitude) goes from -180 to 180 as seen from {@link #getMinX()} and {@link #getMaxX()}.
