destroy()

destroy(): void

Defined in: packages/core/src/renderer/layer-manager.ts:788

Returns

void

---

disconnectStream()

disconnectStream(layerId): void

Defined in: packages/core/src/renderer/layer-manager.ts:735

Disconnect streaming connection for a layer

Parameters

Parameter	Type
layerId	string

Returns

void

---

getSourceData()

getSourceData(sourceId): FeatureCollection<Geometry, GeoJsonProperties> | undefined

Defined in: packages/core/src/renderer/layer-manager.ts:236

The GeoJSON this manager last delivered to a fetched/refreshed source, by source id — what fitTo (U14) frames once a url: source’s first fetch lands. Undefined for sources whose data never passed through here.

Parameters

Parameter	Type
sourceId	string

Returns

FeatureCollection<Geometry, GeoJsonProperties> | undefined

---

getSourceIdForLayer()

getSourceIdForLayer(layerId): string | undefined

Defined in: packages/core/src/renderer/layer-manager.ts:241

The MapLibre source a layer draws from.

Parameters

Parameter	Type
layerId	string

Returns

string | undefined

---

isRefreshing()

isRefreshing(sourceId): boolean

Defined in: packages/core/src/renderer/layer-manager.ts:284

Whether a refresh/stream pipeline is running for a named source.

Parameters

Parameter	Type
sourceId	string

Returns

boolean

---

pauseRefresh()

pauseRefresh(layerId): void

Defined in: packages/core/src/renderer/layer-manager.ts:699

Pause data refresh for a layer (polling)

Parameters

Parameter	Type
layerId	string

Returns

void

---

refreshNow()

refreshNow(layerId): Promise<void>

Defined in: packages/core/src/renderer/layer-manager.ts:713

Force immediate refresh for a layer (polling)

Parameters

Parameter	Type
layerId	string

Returns

Promise<void>

---

registerSources()

registerSources(sources): void

Defined in: packages/core/src/renderer/layer-manager.ts:166

Register the block’s named sources: with MapLibre.

Parameters

Parameter	Type
sources	Record<string, unknown>

Returns

void

Remarks

Owned here rather than in MapRenderer, which used to call map.addSource directly. That bypassed every piece of refresh machinery, so a named source could declare refresh: and never poll, and it leaked YAML-only keys straight into MapLibre. Registration is idempotent so a re-render does not duplicate sources.

---
