Specified by:

contains in interface ShapeSet2D<T extends Curve2D>

curves

java.util.Collection<T> curves()

Returns the collection of curves

Returns:

the inner collection of curves

get

T get(int index)

Specified by:

get in interface ShapeSet2D<T extends Curve2D>

Parameters:

index - index of the curve

Returns:

the i-th inner curve

Since:

0.6.3

childCurve

T childCurve(double t)

Returns the child curve corresponding to a given position.

Parameters:

t - the position on the set of curves, between 0 and twice the number of curves

Returns:

the curve corresponding to the position.

Since:

0.6.3

firstCurve

T firstCurve()

Returns the first curve of the collection if it exists, null otherwise.

Returns:

the first curve of the collection

lastCurve

T lastCurve()

Parameters:

i - the index of the curve to consider

t - the position on the curve

Returns:

the position on the curve set, between 0 and 2*Nc-1
