public class TLcdGML32CompositeCurve extends TLcdGML32AbstractCurve implements ILcdEditableCompositeCurve
A gml:CompositeCurve is represented by a sequence of (orientable) curves such that each curve in the sequence terminates at the start point of the subsequent curve in the list. curveMember references or contains inline one curve in the composite curve. The curves are contiguous, the collection of curves is ordered. Therefore, if provided, the aggregationType attribute shall have the value "sequence".

    • getCurves

      public List<ILcdCurve> getCurves()
      Description copied from interface: ILcdCompositeCurve
      Returns a list with the curve's elements. Each sub-curve's end point, except for the last sub-curve, must coincide with the next sub-curve's start point.

      The returned list is not guaranteed to be editable. See ILcdEditableCompositeCurve for an editable variant of this interface.

      Note that this adding curves to the result of calling this method may throw a ClassCastException or IllegalArgumentException in case the class of the curve(s) to add is not compatible with the implementation of the composite curve. Implementations should specify in their documentation all restrictions that apply in this context.

      Returns the number of intersections between this curve and a line segment defined by the two specified points.

      This information can be used to perform containment calculations, if this curve is closed or if this curve is part of a composite closed curve. By determining the number of intersections between this curve and a line segment starting from a given point in a fixed direction, one can determine whether a point is located within the closed curve by using the even-odd rule.

    • clone

      public TLcdDataObject clone(Map aObjectDictionary)
      Description copied from class: TLcdDataObject
      Returns a deep clone of this object. If the clone is not already present in the dictionary, a new instance if created as follows:
      • First, a new instance is created using Java's clone() mechanism.
      • Then, all properties of this object are cloned and set on the newly created instance. A property is cloned as follows:
        • If the property value is an ILcdDataObject, the value is cloned by first creating a new instance via the value.getDataType().newInstance() method, and then cloning its properties one by one.
        • If the value implements ILcdDeepCloneable or ILcdCloneable then this interface is used to clone the value.
        • Otherwise, the property value is copied by reference.
      Specified by:
      clone in interface ILcdDeepCloneable
      Overrides:
      clone in class TLcdDataObject
