Method Detail

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 name

NullPointerException - 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.

toConf

public String toConf()

assign

public abstract void assign(BoltDeclarer declarer,
                            InputStream stream)
