public interface BSplineType
extends AbstractCurveSegmentType

A representation of the model object 'BSpline Type'. A B-Spline is a piecewise parametric polynomial or rational curve described in terms of control points and basis functions. Knots are breakpoints on the curve that connect its pieces. They are given as a non-decreasing sequence of real numbers. If the weights in the knots are equal then it is a polynomial spline. The degree is the algebraic degree of the basis functions.

The following features are supported:

• Group
• Pos
• Point Property
• Point Rep
• Pos List
• Coordinates
• Degree
• Knot
• Interpolation
• Is Polynomial
• Knot Type

• Gml311Package.getBSplineType()

getGroup

FeatureMap getGroup()

Returns the value of the 'Group' attribute list. The list contents are of type FeatureMap.Entry.

If the meaning of the 'Group' attribute list isn't clear, there really should be more of a description here...

Returns:

the value of the 'Group' attribute list.

See Also:

• Gml311Package.getBSplineType_Group()

getPos

EList<DirectPositionType> getPos()

Returns the value of the 'Pos' containment reference list. The list contents are of type DirectPositionType.

If the meaning of the 'Pos' containment reference list isn't clear, there really should be more of a description here...

getPointProperty

EList<PointPropertyType> getPointProperty()

Returns the value of the 'Point Property' containment reference list. The list contents are of type PointPropertyType.

Returns:

the value of the 'Point Rep' containment reference list.

See Also:

• Gml311Package.getBSplineType_PointRep()

getPosList

DirectPositionListType getPosList()
