THotPDF.GetLoadedXRefMergeInfo

Returns the merge decisions recorded while loading xref streams, hybrid-reference sections, and incremental revision chains

Declaration

function GetLoadedXRefMergeInfo(
  out Info: THPDFXRefMergeInfo
): boolean;

Result

The method returns True when a hybrid section or a cross-reference overlap was observed and always copies the latest diagnostic record to Info

Precedence rules

• Cross-reference sections are traversed from newest revision to oldest revision
• An older entry never replaces an object number already supplied by a newer revision
• Within a hybrid revision, the /XRefStm side stream is merged before the traditional table stub

Fields

• HybridRevisionCount counts revisions with an /XRefStm side stream
• HybridOverlapCount counts same-revision table entries already supplied by that stream
• OlderRevisionShadowedEntryCount counts older definitions rejected by newest-revision precedence
• DuplicateEntryCount counts repeated entries in the newest non-hybrid section
• NewestRevisionPrecedenceApplied and HybridStreamPrecedenceApplied identify rules exercised by the loaded file
