All Implemented Interfaces:
LineBasedGeometry, Serializable, Iterable<LineString>
@NonNullByDefault public class CompoundCurve extends Curve implements Iterable<LineString>
A compound curve is a single, continuous curve that has both curved (circular) segments and linear segments. That means that in addition to having well-formed components, the end point of every component (except the last) must be coincident with the start point of the following component. Just note: here it is treated as a special MultiCurve where the end points of all contained lines match.

    • 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 Curve if the last coordinate is not already the same as the first coordinate.
      Specified by:
      close in class Curve
