## Class AreasBD

- java.lang.Object
- - com.io7m.jregions.core.unparameterized.areas.AreasBD

-     public final class AreasBD
      extends Object

  Functions over areas.

  These functions operate using the concepts of minimum-x, maximum-x, minimum-y, and maximum-y edges. It is up to individual applications to assign meaning to these edges such as "left" for minimum-x and "top" for minimum-y.
