BatchQueryView

Defined in: packages/three-flatland/src/pipeline/batchQuery.ts:47

Read-only view over a world’s batches: a Map<RunKey, SpriteBatch[]> with a classification query —

const lit = group.batches.where(IsLitBatch)

Trait existence is the architectural fact; system implementations may evolve from branch → query-narrowing as workload demands without breaking this surface.

forEach()

forEach(callbackfn, thisArg?): void

Defined in: node_modules/.pnpm/typescript@5.9.3/node_modules/typescript/lib/lib.es2015.collection.d.ts:28

Parameters

callbackfn

thisArg?

any

Returns

void

---

get()

get(key): SpriteBatch[] | undefined

Defined in: node_modules/.pnpm/typescript@5.9.3/node_modules/typescript/lib/lib.es2015.collection.d.ts:33

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

SpriteBatch[] | undefined

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

Parameters

key

string

Returns

boolean

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

Map.keys

---

set()

set(key, value): this

Defined in: node_modules/.pnpm/typescript@5.9.3/node_modules/typescript/lib/lib.es2015.collection.d.ts:41
