Extract a field from an object.

Extract a field from an object, using a one-based index into the field slots. This requires knowledge of the ObjectLayoutVariant, since the same field is at different indices in different variants.

Extract a field from an object, or answer null if it's not present.

Add or replace a field of an object.

Extract a field type from an object type.

Extract a field type from an object type, using the given field index, which is specific to an ObjectLayoutVariant.

The receiver is marked with an IMMUTABLE descriptor, but its subobjects have not yet been made immutable. Scan them now, and do any additional fix-ups necessary for the kind of object.

Replace the object's {@linkplain AbstractDescriptor descriptor}.

Replace my descriptor field with a FillerDescriptor. This blows up for most messages, catching incorrect (all, by definition) further accidental uses of this object.

Answer whether to show value-specific content in the file name for the debugger.

Follow indirections until a non-indirection is reached. Replace each indirection's target with the ultimate target.

Follow indirections until a non-indirection is reached. Replace each indirection's target with the ultimate target, even if it would cause the otherwise-forbidden immutable->mutable references. Only used during makeImmutable.

Follow indirections until a non-indirection is reached. Replace each indirection's target with the ultimate target, even if it would cause the otherwise-forbidden shared->unshared references. Only used during makeShared.
