Class TrackerBase<V, SeenResultType>Abstract

constructor

• new TrackerBase<V, SeenResultType>(opts?): TrackerBase<V, SeenResultType>

• Type Parameters

  • V
  • SeenResultType

  Parameters

  • opts: TrackedValueOpts = {}

Readonlyid

Abstractelapsed

  Returns number

Abstractinitial

• get initial(): undefined | V

• Returns the initial value, or undefined

  Returns void

seen

• seen(...p): SeenResultType

• Adds a value, returning computed result.

  At this point, we check if the buffer is larger than resetAfterSamples. If so, reset() is called. If not, we check sampleLimit. If the buffer is twice as large as sample limit, trimStore() is called to take it down to sample limit, and onTrimmed() is called.

  Parameters

  • Rest...p: V[]

  Returns SeenResultType

AbstracttrimStore

• trimStore(limit): number

• Parameters

  • limit: number

  Returns number
