Detailed Description

template<typename Key, typename Compare>
class spatial::bounds< Key, Compare >

A model of Region Predicate that defines an orthogonal region and checks if a value of type Key is contained within the boundaries marked by lower and upper.

To be very specific, given a dimension $d$ we define that $x$ is contained in the boundaries $(lower, upper)$ if:

$lower_d <= x_d < upper_d$

Simply stated, bounds used in a spatial::region_iterator will match all keys that are within the region defined by lower and upper, but not "touching" the upper edge.

Template Parameters

Key	The type used during the comparison.
Compare	The comparison functor using to compare 2 objects of type `Key` along the same dimension.
