public class PdfADocument
extends PdfDocument

This class extends PdfDocument and is in charge of creating files that comply with the PDF/A standard. Client code is still responsible for making sure the file is actually PDF/A compliant: multiple steps must be undertaken (depending on the PdfAConformanceLevel) to ensure that the PDF/A standard is followed. This class will throw exceptions, mostly PdfAConformanceException, and thus refuse to output a PDF/A file if at any point the document does not adhere to the PDF/A guidelines specified by the PdfAConformanceLevel.
