Interface: VersionedPositionMap

Defined in: packages/core/src/layers/RTLSLayer.ts:27

Issue #456 — A PositionMap that also exposes a monotonically increasing version counter, bumped on every mutating write (set/delete/clear).

tick() in setupRTLSLayer/setupBlueDot compares this counter against the version it last rendered; when unchanged, the frame is skipped entirely (no GeoJSON rebuild, no setData, no setFeatureState/LRU touch).

Consumers that still hand in a plain Map (no version) get the original every-frame behavior — this is purely additive/backward-compatible.

clear()

clear(): void

Defined in: node_modules/.pnpm/typescript@6.0.3/node_modules/typescript/lib/lib.es2015.collection.d.ts:21

Removes all elements from the Map.

Returns

void

delete()

delete(key): boolean

Defined in: node_modules/.pnpm/typescript@6.0.3/node_modules/typescript/lib/lib.es2015.collection.d.ts:25

Parameters

key

entries()

entries(): MapIterator`<[string, PositionUpdate]>`

Defined in: node_modules/.pnpm/typescript@6.0.3/node_modules/typescript/lib/lib.es2015.iterable.d.ts:146

Returns an iterable of key, value pairs for every entry in the map.

forEach()

forEach(callbackfn, thisArg?): void

Defined in: node_modules/.pnpm/typescript@6.0.3/node_modules/typescript/lib/lib.es2015.collection.d.ts:29

Executes a provided function once per each key/value pair in the Map, in insertion order.

Parameters

callbackfn

thisArg?

any

Returns

void

get()

get(key): PositionUpdate | undefined

Defined in: node_modules/.pnpm/typescript@6.0.3/node_modules/typescript/lib/lib.es2015.collection.d.ts:34

Returns a specified element from the Map object. If the value that is associated to the provided key is an object, then you will get a reference to that object and any change made to that object will effectively modify it inside the Map.

Parameters

key

string

Returns

PositionUpdate | undefined

Returns the element associated with the specified key. If no element is associated with the specified key, undefined is returned.

has()

has(key): boolean

Defined in: node_modules/.pnpm/typescript@6.0.3/node_modules/typescript/lib/lib.es2015.collection.d.ts:38

Parameters

key

string

Returns

boolean

boolean indicating whether an element with the specified key exists or not.

keys()

keys(): MapIterator`<string>`

Defined in: node_modules/.pnpm/typescript@6.0.3/node_modules/typescript/lib/lib.es2015.iterable.d.ts:151

Returns an iterable of keys in the map

Returns

MapIterator`<string>`

Inherited from

---

set()

set(key, value): this

Defined in: node_modules/.pnpm/typescript@6.0.3/node_modules/typescript/lib/lib.es2015.collection.d.ts:42
