TXFANode.Identity

Unit: HPDFXFA

Declaration

property Identity: UInt64 read FIdentity;

Provides a process-local monotonic identifier assigned at node construction

The identifier distinguishes different node objects even when memory addresses are reused after deletion

Identity is not serialized into XDP and is not a persistent document identifier; a load or snapshot restoration creates new identities

Allocation uses a short critical section so node construction supports Delphi and FPC on Win32 and Win64
