BagOfCurves Class

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

Extends

Inherited methods

Name Inherited from Description
checkForNonLinearPrimitives(): boolean Inherited CurveCollection Return true if the curve collection has any primitives other than LineSegment3d and LineString3d

cloneTransformed(transform: Transform): undefined | CurveCollection Inherited CurveCollection Create a deep copy of transformed curves.
cloneWithExpandedLineStrings(): CurveCollection Inherited CurveCollection Create a deep copy with all linestrings broken down into multiple LineSegment3d.
collectCurvePrimitives(collectorArray?: CurvePrimitive[], smallestPossiblePrimitives: booleanfalse, explodeLineStrings: booleanfalse): CurvePrimitive[] Inherited CurveCollection Return an array containing all CurvePrimitives in the instance.
extendRange(rangeToExtend: Range3d, transform?: Transform): void Inherited CurveCollection Extend (increase) the given range as needed to encompass all curves in the curve collection.
isAlmostEqual(other: GeometryQuery): boolean Inherited CurveCollection Test for exact structure and nearly identical geometry.
isAnyRegion(): this is AnyRegion Inherited CurveCollection Type guard for AnyRegion
isLoop(): this is Loop Inherited CurveCollection Type guard for Loop
isPath(): this is Path Inherited CurveCollection Type guard for Path
maxGap(): number Inherited CurveCollection Return the max gap between adjacent primitives in Path and Loop collections.
projectedParameterRange(ray: Vector3d | Ray3d, lowHigh?: Range1d): undefined | Range1d Inherited CurveCollection Project instance geometry (via dispatch) onto the given ray, and return the extreme fractional parameters
range(transform?: Transform, result?: Range3d): Range3d Inherited CurveCollection Return the range of the entire GeometryQuery tree.
reverseInPlace(): void Inherited CurveCollection Reverse the collection's data so that each child curve's fractional stroking moves in the opposite direction.
sumLengths(): number Inherited CurveCollection Return the sum of the lengths of all contained curves.
tryTransformInPlace(transform: Transform): boolean Inherited CurveCollection Apply transform recursively to children
tryTranslateInPlace(dx: number, dy: number0.0, dz: number0.0): boolean Inherited CurveCollection Try to move the geometry by dx,dy,dz.
areAlmostEqual(a: GeometryQuery, b: GeometryQuery): boolean Static Inherited CurveCollection Apply instance method isAlmostEqual if both are defined.
createCurveLocationDetailOnAnyCurvePrimitive(source: GeometryQuery, fraction: number0.5): undefined | CurveLocationDetail Static Inherited CurveCollection Find any CurvePrimitive in the source and evaluate it at the given fraction.

Properties

Name Type Description
_children Protected AnyCurve[] Array of children.  
children Accessor ReadOnly AnyCurve[] Return the (reference to) array of children

Inherited properties

Name Type Inherited from Description
geometryCategory Readonly Inherited "curveCollection" CurveCollection String name for schema properties
isAnyRegionType Accessor Inherited ReadOnly boolean CurveCollection Return true for planar region types:
* Loop
* ParityRegion
* UnionRegion
isClosedPath Accessor Inherited 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 Inherited boolean CurveCollection Flag for inner loop status.
isOpenPath Accessor Inherited ReadOnly boolean CurveCollection Return true for a Path, i.e. a chain of curves joined head-to-tail
