Stability: 1.1Active Development

Attributes

ref:Object | Function

The reference to the resource that is being tracked.

callback:Function

The callback function to be called when the resource is finalized.

ref:Object | Function

The reference to the resource that is being tracked.

event:string

The event that triggered the finalization. Defaults to 'beforeExit'.

This function behaves exactly like the register, except that the callback will be called when the process emits the beforeExit event if ref object was not garbage collected.

Be aware that all limitations applied to the beforeExit event are also applied to the callback function, this means that there is a possibility that the callback will not be called under special circumstances.
