  • Method Details

    • intersects

      public boolean intersects(GeoShape geoShape)
      Description copied from interface: GeoAreaShape
      Assess whether a shape intersects with any of the edges of this shape. Note well that this method must return false if the shape contains or is disjoint with the given shape. It is permissible to return true if the shape is within the specified shape, if it is difficult to compute intersection with edges.
      Specified by:
      intersects in interface GeoAreaShape
      Parameters:
      geoShape - is the shape to assess for intersection with this shape's edges.
      Returns:
      true if there's such an intersection, false if not.
    • getRelationship

      public int getRelationship(GeoShape geoShape)
      Description copied from interface: GeoArea
      Find the spatial relationship between a shape and the current geo area. Note: return value is how the GeoShape relates to the GeoArea, not the other way around. For example, if this GeoArea is entirely within the shape, then CONTAINS should be returned. If the shape is entirely enclosed by this GeoArea, then WITHIN should be returned.

      It is permissible to return OVERLAPS instead of WITHIN if the shape intersects with the area at even a single point. So, a circle inscribed in a rectangle could return either OVERLAPS or WITHIN, depending on implementation. It is not permissible to return CONTAINS or DISJOINT in this circumstance, however.

      Similarly, it is permissible to return OVERLAPS instead of CONTAINS under conditions where the shape consists of multiple independent overlapping subshapes, and the area overlaps one of the subshapes. It is not permissible to return WITHIN or DISJOINT in this circumstance, however.

      Specified by:
      getRelationship in interface GeoArea
      Parameters:
      geoShape - is the shape to consider.
      Returns:
      the relationship, from the perspective of the shape.
    • isShapeInsideGeoAreaShape

      protected int isShapeInsideGeoAreaShape(GeoShape geoShape)
      Determine the relationship between the GeoAreShape and the shape's edgepoints.
      Parameters:
      geoShape - is the shape.
      Returns:
      the relationship.
    • isGeoAreaShapeInsideShape

      protected int isGeoAreaShapeInsideShape(GeoShape geoshape)
      Determine the relationship between the GeoAreShape's edgepoints and the provided shape.
      Parameters:
      geoshape - is the shape.
      Returns:
      the relationship.
