values
public static GroupingType[] 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 (GroupingType c : GroupingType.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static GroupingType 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 nameNullPointerException
- if the argument is null
-
fromConf
public static GroupingType fromConf(String conf)
Parse a String config value and covert it into the enum.- Parameters:
conf
- the string config.- Returns:
- the parsed grouping type or SHUFFLE if conf is null.
- Throws:
IllegalArgumentException
- if parsing does not work.
