API Reference > geometry-core > Curve > BagOfCurves BagOfCurves Class A BagOfCurves object is a collection of AnyCurve objects. A BagOfCurves has no implied properties such as being planar. Extends CurveCollection Methods Name Description constructor(): BagOfCurves Construct an empty BagOfCurves announceToCurveProcessor(processor: RecursiveCurveProcessor, indexInParent: number = -1): void invoke processor.announceBagOfCurves(this, indexInParent); cloneEmptyPeer(): BagOfCurves Return an empty BagOfCurves cloneStroked(options?: StrokeOptions): BagOfCurves Clone all children in stroked form. dgnBoundaryType(): number Return the boundary type (0) of a corresponding MicroStation CurveVector dispatchToGeometryHandler(handler: GeometryHandler): any Second step of double dispatch: call handler.handleBagOfCurves(this) getChild(i: number): AnyCurve | undefined Get a child by index isSameGeometryClass(other: GeometryQuery): boolean test if other is an instance of BagOfCurves tryAddChild(child: AnyCurve | undefined): boolean Add a child create(...data: AnyCurve[]): BagOfCurves Static create with given curves. Inherited methods Name Inherited from Description checkForNonLinearPrimitives(): boolean CurveCollection return true if the curve collection has any primitives other than LineSegment3d and LineString3d clone(): CurveCollection | undefined CurveCollection Return a deep copy. cloneTransformed(transform: Transform): CurveCollection | undefined CurveCollection Create a deep copy of transformed curves. cloneWithExpandedLineStrings(): CurveCollection | undefined CurveCollection Create a deep copy with all linestrings expanded to multiple LineSegment3d. collectCurvePrimitives(collectorArray?: CurvePrimitive[], smallestPossiblePrimitives: boolean = false): CurvePrimitive[] CurveCollection Return an array containing only the curve primitives. extendRange(rangeToExtend: Range3d, transform?: Transform): void CurveCollection Extend (increase) rangeToExtend as needed to include these curves (optionally transformed) isAlmostEqual(other: GeometryQuery): boolean GeometryQuery test for exact structure and nearly identical geometry. maxGap(): number CurveCollection return the max gap between adjacent primitives in Path and Loop collections. range(transform?: Transform, result?: Range3d): Range3d GeometryQuery return the range of the entire (tree) GeometryQuery sumLengths(): number CurveCollection Return the sum of the lengths of all contained curves. tryTransformInPlace(transform: Transform): boolean CurveCollection Apply transform recursively to children tryTranslateInPlace(dx: number, dy: number = 0, dz: number = 0): boolean GeometryQuery try to move the geometry by dx,dy,dz createCurveLocationDetailOnAnyCurvePrimitive(source: GeometryQuery | undefined, fraction: number = 0.5): CurveLocationDetail | undefined Static CurveCollection * Find any curve primitive in the source.
