PdfReferenceResolver typedef

PdfReferenceResolver = PdfDataType? Function(PdfRefToken ref)

Decides what an indirect reference read by the parser becomes in the writing model.

Returning null means the value must disappear: in dictionaries the key is removed — which the specification treats as equivalent to null — and in arrays the item vanishes or becomes null, per PdfArrayGapPolicy.

Implementation

typedef PdfReferenceResolver = PdfDataType? Function(PdfRefToken ref);
