contains
Returns whether the path identified by pointer resolves to a value within this element.
Distinguishes "absent" from "present and JsonNull": a path whose value is JsonNull returns true.
Return
true if the path resolves to a value (including kotlinx.serialization.json.JsonNull); false if any segment is absent or out of bounds, or if the path attempts to navigate into a primitive.
Parameters
pointer
The KPointer to test.
