Class TrackerBase<V, SeenResultType>Abstract

Abstractelapsed

• get elapsed(): number

  Returns the elapsed milliseconds since the initial value

  Returns number

Abstractinitial

• get initial(): undefined | V

  Returns the initial value, or undefined

  Returns undefined | V

Abstractlast

• get last(): undefined | V

  Returns undefined | V

constructor

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

  Type Parameters

  • V
  • SeenResultType

  Parameters

  • opts: TrackedValueOpts = {}

  Returns TrackerBase<V, SeenResultType>

AbstractonTrimmed

• onTrimmed(reason: TrimReason): void

  Notification that buffer has been trimmed

  Parameters

  • reason: TrimReason

  Returns void

reset

• reset(): void

  Reset tracker

  Returns void

seen

• seen(...p: V[]): 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

  • ...p: V[]

  Returns SeenResultType

AbstracttrimStore

• trimStore(limit: number): number

  Parameters

  • limit: number

  Returns number
