Class S2RegionIntersection

java.lang.Object
com.google.common.geometry.S2RegionIntersection
All Implemented Interfaces:
S2Region, Serializable
@GwtCompatible(serializable=true) public class S2RegionIntersection extends Object implements S2Region, Serializable
An S2RegionIntersection represents an intersection of overlapping regions. It is convenient for computing a covering of the intersection of a set of regions. The regions are assumed to be immutable. Note: An intersection of no regions covers the entire sphere.

  • Method Details

    • contains

      public boolean contains(S2Cell cell)
      Returns true if all the regions fully contain the cell.
      Specified by:

      public boolean contains(S2Point point)
      Returns true if all the regions fully contain the point.
      Specified by:
      contains in interface S2Region

    • getCapBound

      public S2Cap getCapBound()
      Description copied from interface: S2Region
      Return a bounding spherical cap.
      Specified by:
      getCapBound in interface S2Region

    • getRectBound

      public S2LatLngRect getRectBound()
      Description copied from interface: S2Region
      Return a bounding latitude-longitude rectangle.

    • mayIntersect

      public boolean mayIntersect(S2Cell cell)
      Returns true if the cell may intersect all regions in this collection.
      Specified by:

    • equals

      public boolean equals(Object thatObject)
      Returns true if this S2RegionIntersection is equal to another S2RegionIntersection, where each region must be equal and in the same order. This method is intended only for testing purposes. NOTE: This should be rewritten to disregard order if such functionality is ever required.
