public class CompositeCurveImpl
extends CompositeImpl<OrientableCurveImpl>
implements CompositeCurve

A composite curve, CompositeCurve shall be a Composite with all the geometric properties of a curve. These properties are instantiated in the operation "curve". Essentially, a composite curve is a list of orientable curves (OrientableCurve) agreeing in orientation in a manner such that each curve (except the first) begins where the previous one ends.

Constructor Detail

CompositeCurveImpl

public CompositeCurveImpl(List<OrientableCurve> generator)

The association role Composition::generator associates this CompositeCurve to the primitive Curves and OrientableCurves in its generating set, the curves that form the core of this complex. CompositeCurve::generator : Sequence -- the start point of each orientable curve in the generator is the -- end point of the previous one CompositeCurve: forAll (1 < j < generator.count - 1)? generator[j].endPoint = generator[j+1].startPoint; NOTE To get a full representation of the elements in the Complex, the Points on the boundary of the generator set of Curve would be added to the curves in the generator list. The generator elements will be passed through the super constructor. The plausibility of the Curves will be checked within the constructor of the CompositeCurve Constructs a Composite Curve

Parameters:

generator -

Method Detail

getElements

public List<Primitive> getElements()

Description copied from class: ComplexImpl

Returns elements contained in this Complex

Specified by:

getElements in interface Complex

Overrides:

getElements in class ComplexImpl

Returns:

the primitives

createBoundary

public Set<Complex> createBoundary()

Specified by:

createBoundary in class ComplexImpl

Returns:

Set

getGeneratorClass

public Class getGeneratorClass()

Specified by:

getGeneratorClass in class CompositeImpl<OrientableCurveImpl>

Returns:

the class

getDimension

public int getDimension(DirectPositionImpl point)

The method dimension returns the inherent dimension of this Object, which is less than or equal to the coordinate dimension. The dimension of a collection of geometric objects is the largest dimension of any of its pieces. Points are 0-dimensional, curves are 1-dimensional, surfaces are 2-dimensional, and solids are 3-dimensional. Locally, the dimension of a geometric object at a point is the dimension of a local neighborhood of the point - that is the dimension of any coordinate neighborhood of the point. Dimension is unambiguously defined only for DirectPositions interior to this Object. If the passed DirectPosition2D is NULL, then the method returns the largest possible dimension for any DirectPosition2D in this Object.

Parameters:

point - a DirectPosition2D value

Returns:

an int value
