    • spatiallyEquals

      public boolean spatiallyEquals(Geometry o, PrecisionModel precisionModel)
      Description copied from class: LineString
      Tests if this geometry is equal to the argument, on a topological point of view.
      Specified by:
      spatiallyEquals in interface Geometry
      Overrides:
      spatiallyEquals in class LineString
      Parameters:
      o - the geometry to be tested.
      precisionModel - the precision model to use while comparing geometries.
      Returns:
      whether both geometries are spatially equals.

    • spatiallyEquals

      public boolean spatiallyEquals(LinearRing ring)
      Tests if this geometry is equal to the argument, on a topological point of view
      it means that they represents the same geometry, even if it is described differently (orientation of the rings, order of the rings)
      it does not remove additional points on lineString (3 points aligned), one must use smoother.removeExtraPoints() before in order to achieve that. here we first try to find a common point, then test equality in both orientation,

    • getGeometryId

      public short getGeometryId()
      Description copied from class: LineString
      Returns the geometry class id. This method is useful for geometry serialization.
      Specified by:
      getGeometryId in interface Geometry
      Overrides:
      getGeometryId in class LineString
      Returns:
      the geometry id.

    • isValid

      public boolean isValid()
      Tests if the ring is valid. To be valid : Must have 0 or at least 3 coordinates, and first and last coordinate must be equal.
      Returns:
      true if valid
