Enum PDFAFlavour

java.lang.Object

java.lang.Enum<PDFAFlavour>

org.verapdf.pdfa.flavours.PDFAFlavour

All Implemented Interfaces:

Serializable, Comparable<PDFAFlavour>

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 3 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
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
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

Method Detail

values

public static PDFAFlavour[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (PDFAFlavour c : PDFAFlavour.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static PDFAFlavour valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type 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. 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
