Accessors

elapsed

  • get elapsed(): number

  • Returns the elapsed time, in milliseconds since the instance was created

    Returns number

initial

  • get initial(): undefined | V

  • Returns the initial value, or undefined

    Returns undefined | V

last

  • get last(): undefined | V

  • Returns undefined | V

size

  • get size(): number

  • Returns number of recorded values (this can include the initial value)

Methods

filterData

onTrimmed

reset

seen

  • seen(...p): TResult

  • 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 TResult

trimStore

  • trimStore(limit): number

  • Reduces size of value store to limit. Returns number of remaining items

    Parameters

    • limit: number

    Returns number
