## Class GeoBaseMembershipShape

- java.lang.Object
- - org.apache.lucene.spatial3d.geom.BasePlanetObject
  - - org.apache.lucene.spatial3d.geom.GeoBaseShape
    - - org.apache.lucene.spatial3d.geom.GeoBaseMembershipShape

- All Implemented Interfaces:
    GeoMembershipShape, GeoOutsideDistance, GeoShape, Membership
  Direct Known Subclasses:
    GeoBaseDistanceShape, GeoDegenerateVerticalLine

      public abstract class GeoBaseMembershipShape
      extends GeoBaseShape
      implements GeoMembershipShape

  Membership shapes have capabilities of both geohashing and membership determination. This is a useful baseclass for them.
  WARNING: This API is experimental and might change in incompatible ways in the next release.

    - #### GeoBaseMembershipShape

          public GeoBaseMembershipShape(PlanetModel planetModel)

      Constructor.
      Parameters:
        `planetModel` - is the planet model to use.

  - ### Method Detail

    - #### isWithin

          public boolean isWithin(Vector point)

      Description copied from interface: `Membership`
      Check if a point is within this shape.
      Specified by:
        `isWithin` in interface `Membership`
      Parameters:
        `point` - is the point to check.
      Returns:
        true if the point is within this shape

    - #### computeOutsideDistance

          public double computeOutsideDistance(DistanceStyle distanceStyle,
                                               GeoPoint point)

      Description copied from interface: `GeoOutsideDistance`
      Compute this shape's distance to the GeoPoint. A return value of 0.0 should be returned for points inside of the shape.
      Specified by:
        `computeOutsideDistance` in interface `GeoOutsideDistance`
      Parameters:
        `distanceStyle` - is the distance style.
        `point` - is the point to compute the distance to.
      Returns:
        the distance.

    - #### computeOutsideDistance

          public double computeOutsideDistance(DistanceStyle distanceStyle,
                                               double x,
                                               double y,

      Description copied from interface: `GeoOutsideDistance`
      Compute this shape's distance to the GeoPoint. A return value of 0.0 should be returned for points inside of the shape.
      Specified by:
        `computeOutsideDistance` in interface `GeoOutsideDistance`
      Parameters:
        `distanceStyle` - is the distance style.
        `x` - is the point's unit x coordinate (using U.S. convention).
        `y` - is the point's unit y coordinate (using U.S. convention).
        `z` - is the point's unit z coordinate (using U.S. convention).
      Returns:
        the distance.
