tryWithPath

Callable

• tryWithPath(reference: undefined | null | EntityReference, ...segments: string[]): EntityReference | undefined

---

• withPath, returning undefined where it throws. Also undefined for an undefined or null reference, so it chains onto another try* form without a check in between.

  Any refused input yields undefined, including one of the wrong type from an untyped caller -- except that with no segments the reference is returned as given, unvalidated.

  ---

  Parameters

  • reference: undefined | null | EntityReference

  • rest...segments: string[]

  Returns EntityReference | undefined
