o_MakeSubobjectsImmutable

open override fun o_MakeSubobjectsImmutable(self: AvailObject): AvailObject

{@inheritDoc}

Make my subobjects be immutable. Don't change my own mutability state. Also, ignore my mutability state, as it should be tested (and sometimes set preemptively to immutable) prior to invoking this method.

Return

The receiving AvailObject.
