hasEventListener

hasEventListener<T>(type, listener): boolean
Checks if listener is added to an event type.
Type Parameters
- T extends keyof OperationCounterEvents
Parameters
- type: T
  The type of event to listen to.
- listener: EventListener<OperationCounterEvents[T], T, OperationCounter>
  The function that gets called when the event is fired.

increment

increment(count?): void
Increment the number of pending operations.
Parameters
- count: number = 1
  How many increments to do. Default is 1.
Returns void
- Defined in core/OperationCounter.ts:84

removeEventListener

removeEventListener<T>(type, listener): void
Removes a listener from an event type.
Type Parameters
- T extends keyof OperationCounterEvents
Parameters
- type: T
  The type of the listener that gets removed.
- listener: EventListener<OperationCounterEvents[T], T, OperationCounter>
  The listener function that gets removed.

- Defined in ../node_modules/@types/three/src/core/EventDispatcher.d.ts:78

wrap

wrap<T>(promise): Promise<T>
Increments the counter before starting the promise, then decrements it safely when the promises resolves or fails.
Type Parameters
- T
Parameters
- promise: Promise<T>
Returns Promise<T>
