Method Detail

values

public static AdqlVersion[] 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 (AdqlVersion c : AdqlVersion.values())
    System.out.println(c);

Returns:

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

valueOf

public static AdqlVersion 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

getName

public String getName()

Returns the informal name of this version.

Returns:

version name, suitable for presentation to user

getNumber

public String getNumber()

Returns the version number as a string.

Returns:

X.Y format version number

getIvoid

public Ivoid getIvoid()

Returns the version identifier string.

Returns:

URI, currently of the form ivo://ivoa.net/std/ADQL#vX.Y

getFeatureUris

public Ivoid[] getFeatureUris()

Returns an array of all the language feature URIs defined by this version. These currently all have the form "ivo://ivoa.net/std/TAPRegExt#features-*". These are defined in the TAPRegExt and ADQL standards.

Returns:

language feature URIs

toString

public String toString()

Overrides:

toString in class Enum<AdqlVersion>

byNumber
