Class Profiles

java.lang.Object
org.verapdf.pdfa.validation.profiles.Profiles
public final class Profiles extends Object
Utitlity class that provides helper methods for handling ValidationProfiles and associated classes.

The utility methods generally fall into one of the following categories:

  • default instance creators, defaultTypeName(), used for testing or when a vanilla instance of a particular type is required.
  • from values instance creators, typeNameFromValues(...), used to create instances from their contained types.
  • XML helper methods, typeNameToXml(...), to facilitate XML serialisation to Strings, OutputStreams and Writers.
  • XML helper methods, typeNameFromXml(...), to facilitate XML deserialisation.
Note that XML serialisation and de-serialisation is achieved through JAXB bindings.
