Class TimeRangeKeyColumn

constructor

• new TimeRangeKeyColumn(
      begin: Float64Array,
      end: Float64Array,
      length: number,
  ): TimeRangeKeyColumn

  Parameters

  • begin: Float64Array
  • end: Float64Array
  • length: number

  Returns TimeRangeKeyColumn

Readonlykind

Readonlylength

at

• at(i: number): TimeRangeKeyAt | undefined

  Returns { begin, end } at row i, or undefined for out-of-range. Raw POJO; consumers wanting the TimeRange class use the row-API path.

  Parameters

  • i: number

  Returns TimeRangeKeyAt | undefined

beginAt

• beginAt(i: number): number

  Direct buffer read: begin[i]. Throws on out-of-range.

  Parameters

  • i: number

  Returns number

endAt

• endAt(i: number): number

  Direct buffer read: end[i]. Throws on out-of-range.

  Parameters

  • i: number

  Returns number

slice

• slice(start: number, end: number): TimeRangeKeyColumn

  Parameters

  • start: number
  • end: number

  Returns TimeRangeKeyColumn

sliceByIndices

• sliceByIndices(indices: Int32Array): TimeRangeKeyColumn

  Gathers rows by index into a new TimeRangeKeyColumn. See TimeKeyColumn.sliceByIndices for the out-of-range semantics.

  Parameters

  • indices: Int32Array

  Returns TimeRangeKeyColumn

sliceByRange

• sliceByRange(start: number, end: number): TimeRangeKeyColumn

  Zero-copy index-range view: returns a TimeRangeKeyColumn over begin.subarray(s, e) + end.subarray(s, e). Same trusted- buffer-immutability contract as the source.

  Note on max-end: the range-key invariant says begin[i] <= end[i] per row, NOT that end[i] is monotonically increasing. A long early event can extend past the final row's end. The slice preserves this — out.end[length - 1] is the end of the final row in the slice, NOT the maximum end across the slice. See RFC §4 close-cases for why range-key max-end is deferred.

  Parameters

  • start: number
  • end: number

  Returns TimeRangeKeyColumn
