An abstract class that will run through all necessary checks defined in the different PDF/A standards and levels.

An abstract class that will run through all necessary checks defined in the different PDF/A standards and levels. A number of common checks are executed in this class, while standard-dependent specifications are implemented in the available subclasses. The standard that is followed is the series of ISO 19005 specifications, currently generations 1 through 3. The ZUGFeRD standard is derived from ISO 19005-3. While it is possible to subclass this method and implement its abstract methods in client code, this is not encouraged and will have little effect. It is not possible to plug custom implementations into iText, because iText should always refuse to create non-compliant PDF/A, which would be possible with client code implementations. Any future generations of the PDF/A standard and its derivates will get their own implementation in the iText 7 - pdfa project.

The maximum Graphics State stack depth in PDF/A documents, i.e. the maximum number of graphics state operators with code q that may be opened (i.e. not yet closed by a corresponding Q) at any point in a content stream sequence.

The maximum Graphics State stack depth in PDF/A documents, i.e. the maximum number of graphics state operators with code q that may be opened (i.e. not yet closed by a corresponding Q) at any point in a content stream sequence. Defined as 28 by PDF/A-1 section 6.1.12, by referring to the PDF spec Appendix C table 1 "architectural limits".

Contains some objects that are already checked.

Contains some objects that are already checked. NOTE: Not all objects that were checked are stored in that set. This set is used for avoiding double checks for actions, xObjects and page objects; and for letting those objects to be manually flushed. Use this mechanism carefully: objects that are able to be changed (or at least if object's properties that shall be checked are able to be changed) shouldn't be marked as checked if they are not to be flushed immediately.

This method checks a number of document-wide requirements of the PDF/A standard.

This method checks a number of document-wide requirements of the PDF/A standard. The algorithms of some of these checks vary with the PDF/A level and thus are implemented in subclasses; others are implemented as private methods in this class. The catalog being checked

This class extends 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 ) to ensure that the PDF/A standard is followed. This class will throw exceptions, mostly , 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 .
