BagOfCurves Class

  • A BagOfCurves object is a collection of AnyCurve objects.
  • A BagOfCurves has no implied properties such as being planar.



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( AnyCurve[]): BagOfCurves Static create with given curves.

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(): 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

Inherited properties

Name Type Inherited from Description
geometryCategory "curveCollection" = "curveCollection" CurveCollection  
isAnyRegionType Accessor ReadOnly boolean CurveCollection Return true for planar region types:
* UnionRegion
isClosedPath Accessor ReadOnly boolean CurveCollection Return true for a single-loop planar region type, i.e. Loop.
* This is _not- a test for physical closure of a Path
isInner boolean CurveCollection Flag for inner loop status.
isOpenPath Accessor ReadOnly boolean CurveCollection Return true for a Path, i.e. a chain of curves joined head-to-tail
