      • addRing

        public void addRing​(T ring)
        Adds a ring.
        Parameters:
        ring - ring

      • checkConsistency

        public boolean checkConsistency()
        Description copied from class: Geometry
        Do some internal consistency checks on the geometry. Currently, all Geometries must have a valid dimension (2 or 3) and a valid type. Composed geometries must have all equal SRID, dimensionality and measures, as well as that they do not contain NULL or inconsistent subgeometries. BinaryParser and WKTParser should only generate consistent geometries. BinaryWriter may produce invalid results on inconsistent geometries.
        Overrides:
        checkConsistency in class Geometry
        Returns:
        true if all checks are passed.

      • clearRings

        public void clearRings()
        Clears all rings.
