Package com.pd4ml.pdf.xfdf

XFDF (ISO 19444-1): exports a PDF document's annotations and form field values to XFDF, and imports them from it.

Class Summary

Class	Description
XfdfAnnotation	One <annots> entry (or a nested <popup>) -- a plain, generic bag of the XFDF attributes and child elements defined across every markup annotation type in ISO 19444-1 §6.4, rather than a separate Java class per PDF annotation subtype.
XfdfDocument	The parsed/in-memory form of one XFDF document (ISO 19444-1): the flat list of resolved XfdfFields from <fields> (see XfdfField.getQualifiedName() for how a nested <field> hierarchy collapses into this list), and the top-level XfdfAnnotations from <annots> (each already carrying its own nested <popup>, if it has one, rather than that popup also appearing separately in this list).
XfdfExporter	Exports a PDF's markup annotations and AcroForm field values to an XFDF document (ISO 19444-1) -- built entirely on the pd4ml com.pd4ml.pdf.cos object model/parser (no PDFBox, no other PDF library), the same foundation com.pd4ml.pdf.sign, com.pd4ml.pdf.merge and com.pd4ml.pdf.optimizer are built on.
XfdfExporter.Options	Export-time settings: the input password, and an optional type/ID subset to export.
XfdfField	One <field> entry under <fields> (ISO 19444-1 §6.3): a form field's fully-qualified name and its current value(s).
XfdfImporter	Imports an XFDF document's (ISO 19444-1) annotations and form field values into a PDF -- built entirely on the pd4ml com.pd4ml.pdf.cos object model/parser (no PDFBox, no other PDF library), the same foundation com.pd4ml.pdf.sign, com.pd4ml.pdf.merge and com.pd4ml.pdf.optimizer are built on.
XfdfImporter.Options
XfdfImporter.Result	The imported PDF, plus bookkeeping on what the import actually did.
XfdfReader	Parses an XFDF document (ISO 19444-1) into an XfdfDocument.
XfdfWriter	Serializes an XfdfDocument to XFDF XML bytes (ISO 19444-1), hand-rolled the same way com.pd4ml.pdf.merge.internal.PdfConformance builds its XMP packets, rather than pulling in a DOM/serializer dependency for what is, structurally, a very small and fixed document shape.

Exception Summary

Exception	Description
XfdfException	Checked exception wrapping any failure that occurs while parsing an XFDF document, loading the PDF it targets, or applying/extracting annotation and form field data between the two.
