getNotSetSentinel

Callable

• getNotSetSentinel(size: number): number

---

• Returns the sentinel value (not-set indicator) for a given index size.

  @deprecated

  Derives the sentinel from the length of the indexed table, which is not what the writer keys the width on - use getNotSetSentinelForIndexWidth with the channel's BYTES_PER_ELEMENT instead. The size parameter is an element count, so passing an IndexSize member yields the u8 sentinel for every width.

  Parameters

  • size: number

    The size of the array that is indexed (number of elements)

  Returns number

  The appropriate sentinel value (0xff, 0xffff, or 0xffffffff)
