Interface LinesDataLoader

Data loader interface for Lines nodes.

Mirrors the DataLoader interface from points but specialized for lines.

interface LinesDataLoader {
    loadLines(
        viewState: ViewState,
        session?: UpdateSession,
    ): Promise<LoadedLinesData>;
    updateView(
        viewState: ViewState,
        session?: UpdateSession,
        signal?: AbortSignal,
        residencyAllowanceBytes?: number,
    ): Promise<LoadedLinesData>;
    dispose(): void;
    addEventListener?(listener: MonitorEventListener): void;
    removeEventListener?(listener: MonitorEventListener): void;
    getMetrics?(): LoaderMetrics;
    getActiveQueries?(): QueryInfo[];
}

Methods

loadLines

loadLines(
viewState: ViewState,
session?: UpdateSession,
): Promise<LoadedLinesData>
Load lines data for the given view state
Parameters
- viewState: ViewState
- Optionalsession: UpdateSession
Returns Promise<LoadedLinesData>
- Defined in src/types/lines.ts:461

updateView

updateView(
    viewState: ViewState,
    session?: UpdateSession,
    signal?: AbortSignal,
    residencyAllowanceBytes?: number,
): Promise<LoadedLinesData>
Update existing data for a new view state (see DataLoader.updateView for signal).
Parameters
- viewState: ViewState
- Optionalsession: UpdateSession
- Optionalsignal: AbortSignal
- OptionalresidencyAllowanceBytes: number
Returns Promise<LoadedLinesData>
- Defined in src/types/lines.ts:464

dispose

dispose(): void
Clean up resources

Returns void
- Defined in src/types/lines.ts:472

`Optional`addEventListener

addEventListener?(listener: MonitorEventListener): void
LoaderMonitor surface (optional, for the data-loading-monitor UI). Mirrors the surface that points-spatial-index-loader.ts exposes — implementations that don't track metrics may omit these methods.
Parameters
- listener: MonitorEventListener
Returns void
- Defined in src/types/lines.ts:479

`Optional`removeEventListener

removeEventListener?(listener: MonitorEventListener): void
Parameters
- listener: MonitorEventListener
Returns void
- Defined in src/types/lines.ts:480

`Optional`getMetrics

getMetrics?(): LoaderMetrics
Returns LoaderMetrics
- Defined in src/types/lines.ts:481

`Optional`getActiveQueries

getActiveQueries?(): QueryInfo[]
Returns QueryInfo[]
- Defined in src/types/lines.ts:482
