Methods

addLayer

addLayer(
    file: IfcxFile,
    buffer: ArrayBuffer,
    name: string,
    source?: LayerSource,
): string

  Parsed IFCX file
- buffer: ArrayBuffer
  Original buffer
- name: string
  Display name for the layer
- Optionalsource: LayerSource
  Source information
Returns string
Layer ID

addLayerAt

addLayerAt(
    file: IfcxFile,
    buffer: ArrayBuffer,
    name: string,
    position: number,
    source?: LayerSource,
): string
Add a layer at a specific position.
Parameters
- file: IfcxFile
  Parsed IFCX file
- buffer: ArrayBuffer
  Original buffer
- name: string
  Display name
- position: number
  Position in stack (0 = strongest)
- Optionalsource: LayerSource
  Source information
Returns string
Layer ID

clear

clear(): void

Clear all layers.

Returns void

getAllPaths

getAllPaths(): Set<string>

Get all unique paths across all enabled layers.

Returns Set<string>

getEnabledLayers

getEnabledLayers(): IfcxLayer[]

Get only enabled layers in order (strongest first).

Returns IfcxLayer[]

getLayer

getLayer(layerId: string): IfcxLayer | undefined
Get a layer by ID.
Parameters
- layerId: string
Returns IfcxLayer | undefined

getLayers

getLayers(): readonly IfcxLayer[]

Get all layers in order (strongest first).

Returns readonly IfcxLayer[]

getNodesForPath

getNodesForPath(path: string): { layer: IfcxLayer; nodes: IfcxNode[] }[]
Get nodes for a path from all enabled layers, ordered by strength.
Parameters
- path: string
Returns { layer: IfcxLayer; nodes: IfcxNode[] }[]

getStats

getStats(): {
    enabledCount: number;
    layerCount: number;
    totalNodes: number;
    uniquePaths: number;
}

Get summary statistics.

Returns {
    enabledCount: number;
    layerCount: number;
