constructor

+ new UnfoldingNester(groupRepresentationsMap: Map‹PlateGroup, IPlateGroup2DRepresentations›, __namedParameters: [number, number], cancelToken?: CancelToken): UnfoldingNester

Inherited from Nester.constructor

Defined in src/modules/kyub.core.svgObjExporter/src/export/Nester.ts:21

Parameters:

Name	Type	Description
groupRepresentationsMap	Map‹PlateGroup, IPlateGroup2DRepresentations›	a Map that maps PlateGroups to different 2D representations of them. The nester may use solely the polygonWithCutouts representation to get the most space efficient layout or they may use the extended information to better inform their decision.
__namedParameters	[number, number]	-
cancelToken?	CancelToken	optional, use to cancel the nesting progress

Returns: UnfoldingNester
