values
public static JoinType[] 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 (JoinType c : JoinType.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
