    • 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.

    • close

      public void close()
      Closes this LineString if the last coordinate is not already the same as the first coordinate.
      Specified by:
      close in class Curve

    • equals

      public boolean equals(@Nullable Object other)
      Description copied from class: Geometry
      java.lang.Object equals implementation
      Overrides:
      equals in class Geometry

      other - geometry to compare
      Returns:
      true if equal, false otherwise
