THotPDF.GetIncrementalUpdateSourceInfo

Returns file-backing, locking, memory, copy, append, traversal, and xref telemetry for the active incremental update source

Delphi declaration

function GetIncrementalUpdateSourceInfo(
  out Info: THPDFIncrementalSourceInfo
): boolean;

C++Builder declaration

bool __fastcall GetIncrementalUpdateSourceInfo(
  THPDFIncrementalSourceInfo &Info
);

The result is true after BeginIncrementalUpdate establishes an incremental source and false when no source is active

Behaviour

The method is observational and does not change source ownership or save state. Before a save, the counters describe retained source state and tracked mutations. After a save, they also describe prefix copy bytes, appended bytes, visited objects, sparse xref entries, in-place selection, and one-shot source consumption
