## Enum GroupingType

- java.lang.Object
- - java.lang.Enum<GroupingType>
  - - org.apache.storm.loadgen.GroupingType

- All Implemented Interfaces:
    Serializable, Comparable<GroupingType>

      public enum GroupingType
      extends Enum<GroupingType>

  The different types of groupings that are supported.

    - #### ALL

          public static final GroupingType ALL

          public static final GroupingType PARTIAL_KEY

  - ### 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)
