public enum PDFAFlavour extends Enum<PDFAFlavour>
Enums used as id for PDF/A flavours where a flavour uniquely identifies a specific PDF/A Standard part and associated conformance level. The PDF/A Specification:
ISO 19005 - Document Management - Electronic document format for long-term preservation (PDF/A)
comprises 4 parts:
  1. Part 1: PDF/A-1 - Use of PDF 1.4
  2. Part 2: PDF/A-2 - Use of ISO 32000-1
  3. Part 3: PDF/A-3 - Use of ISO 32000-1 with support for embedded files
  4. Part 4: PDF/A-4 - Use of ISO 32000-2
      5. Note that "Use of ISO 32000-1" indicates that PDF/A parts 2 and 3 are based upon PDF 1.7. ISO 32000-1 is the code for the PDF 1.7 ISO standard. The specification parts specify different conformance levels:
      • Level b - basic
      • Level a - accessible
      • Level u - unicode
      • Level f - embedded files
      • Level e - engineering
      Part 1 does not allow a conformance level u (Unicode) so there are eight valid combinations of specification part and level, shown below:
      • 1a
      • 1b
      • 2a
      • 2b
      • 2u
      • 3a
      • 3b
      • 3u
      • 4
      • 4f
      • 4e

  • Method Details

    • values

      public static PDFAFlavour[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static PDFAFlavour valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null

    • getPart

      public final PDFAFlavour.Specification getPart()
      Returns:
      an PDFAFlavour.Specification instance that identifies the Specification Part

    • getLevel

      public final PDFAFlavour.Level getLevel()
      Returns:
      the PDFAFlavour.Level instance for this flavour

    • getId

      public final String getId()
      Returns:
      the two character String id for this flavour, e.g. 1a, 1b, 2a, etc.

    • toString

      public final String toString()
      Overrides:
      toString in class Enum<PDFAFlavour>

    • byFlavourId

      public static PDFAFlavour byFlavourId(String flavourId)
      Looks up a PDFAFlavour by two letter flavour identifier. The identifier is a two letter String that identifies a PDFAFlavour, e.g. 1a, 1b, 2a, 2b, 2u, 3a, 3b, 3u, 4, 4f, 4e. The match is case insensitive so 1A, 1B, etc. are also valid flavour ids.
      Parameters:
      flavourId - must be a two character string that exactly matches the flavour identifier.
      Returns:
      the correct PDFAFlavour looked up by String id or NO_FLAVOUR if id does not match a flavour

    • fromString

      public static PDFAFlavour fromString(String toParse)
      Performs a lenient parse of the String toParse to determine whether it contains a valid PDFAFlavour identifier. Be aware that the identifiers are only 2 character Strings (see byFlavourId(String) so unintended matches are possible.
      Parameters:
      toParse - a String parameter that is parsed to see whether it contains a PDFAFlavour identifier.
      Returns:
      the correct PDFAFlavour looked up by parsing toParse or NO_FLAVOUR if no matching flavour was found.

    • getFlavourIds

      public static Set<String> getFlavourIds()
      Returns:
      the Set of PDFA Flavour String ids
