Method Detail

values

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

Returns:

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

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
