Class CompoundCurve

  • 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.

    • Constructor Detail

      • CompoundCurve

        public CompoundCurve()
        Constructs an instance.

      • CompoundCurve

        public CompoundCurve​(Iterable<? extends LineString> geoms)
        Constructs an instance.
        Parameters:
        geoms - geometries

    • Method Detail

      • add

        public void add​(LineString geom)
        Adds a geometry.
        Parameters:
        geom - geometry

      • addAll

        public final void addAll​(Iterable<? extends LineString> geoms)
        Adds all given geometries.
        Parameters:

      • 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

      • equals

        public boolean equals​(@Nullable
                      Object other)
        Description copied from class: Geometry
        java.lang.Object equals implementation
        Overrides:
        equals in class Geometry
        Parameters:
        other - geometry to compare
        Returns:
        true if equal, false otherwise

      • getGeometries

        public Collection<LineString> getGeometries()
        Gets all geometries.
        Returns:
