API Reference > imodeljs-common > Geometry > GeometryStreamIterator GeometryStreamIterator Class GeometryStreamIterator is a helper class for iterating a GeometryStreamProps. A GeometricElement's GeometryStream must be specifically requested using ElementLoadProps.wantGeometry. Each GeometryStreamIteratorEntry returned by the iterator represents exactly one geometric primitive in the stream. Implements IterableIterator<GeometryStreamIteratorEntry> Methods Name Description constructor(geometryStream: GeometryStreamProps, categoryOrGeometryParams?: string | GeometryParams, localToWorld?: Transform): GeometryStreamIterator Construct a new GeometryStreamIterator given a GeometryStreamProps from either a GeometricElement3d, GeometricElement2d, or GeometryPart. [iterator](): IterableIterator<GeometryStreamIteratorEntry> next(): IteratorResult<GeometryStreamIteratorEntry, any> Advance to next displayable geometric entry while updating the current GeometryParams from appearance related entries. partToWorld(): undefined | Transform Get the transform that if applied to a GeometryPart's GeometryStream entries would return them in world coordinates. fromGeometricElement2d(element: GeometricElement2dProps): GeometryStreamIterator Static Create a new GeometryStream iterator for a GeometricElement2d. fromGeometricElement3d(element: GeometricElement3dProps): GeometryStreamIterator Static Create a new GeometryStream iterator for a GeometricElement3d. fromGeometryPart(geomPart: GeometryPartProps, geomParams?: GeometryParams, partTransform?: Transform): GeometryStreamIterator Static Create a new GeometryStream iterator for a GeometryPart. Properties Name Type Description flags Readonly GeometryStreamFlags Flags applied to the entire geometry stream. geometryStream GeometryStreamProps GeometryStream entries Defined in core/common/src/geometry/GeometryStream.ts Line 507 Last Updated: 11 June, 2024
