The DelphiVCL CleanupInstance method or DelphiVCL.Application.CleanupInstance is used to perform finalization on long strings, variants, and interface variables within a class.
Do not call CleanupInstance directly. CleanupInstance is called automatically when the object instance is destroyed.
CleanupInstance releases all long strings and variants. It sets long strings to empty and variants to Unassigned.
