BEHAVIOR: Reflects framework's internal locking state. Read-only query (locks managed by framework). Values: TGIS_Lock enumeration (Unlocked, ReadLocked, WriteLocked).

USAGE: Check thread-safety:if shape.LockLevel = Unlocked then ModifyShape;

CONSTRAINTS: Read-only (managed by framework). Informational only (not for manual locking). May change during execution.
