## Enum SortedSetSelector.Type

- java.lang.Object
- - java.lang.Enum<SortedSetSelector.Type>
  - - org.apache.lucene.search.SortedSetSelector.Type

- All Implemented Interfaces:
    Serializable, Comparable<SortedSetSelector.Type>
  Enclosing class:
    SortedSetSelector

      public static enum SortedSetSelector.Type
      extends Enum<SortedSetSelector.Type>

  Type of selection to perform.

  Limitations:

  - Fields containing `Integer.MAX_VALUE` or more unique values are unsupported.
  - Selectors other than (`MIN`) require optional codec support. However several codecs provided by Lucene, including the current default codec, support this.

- - ### Enum Constant Summary

    Enum Constants
    Enum Constant and Description
    `MAX` Selects the maximum value in the set
    `MIDDLE_MAX` Selects the middle value in the set.
    `MIDDLE_MIN` Selects the middle value in the set.
    `MIN` Selects the minimum value in the set

  - ### Method Summary

    All Methods Static Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `static SortedSetSelector.Type` | `valueOf(String name)` Returns the enum constant of this type with the specified name.
    `static SortedSetSelector.Type[]` | `values()` Returns an array containing the constants of this enum type, in the order they are declared.

    - #### MIN

          public static final SortedSetSelector.Type MIN

      Selects the minimum value in the set

    - #### MAX

          public static final SortedSetSelector.Type MAX

      Selects the maximum value in the set

    - #### MIDDLE_MIN

          public static final SortedSetSelector.Type MIDDLE_MIN

      Selects the middle value in the set.

      If the set has an even number of values, the lower of the middle two is chosen.

    - #### MIDDLE_MAX

          public static final SortedSetSelector.Type MIDDLE_MAX

      Selects the middle value in the set.

      If the set has an even number of values, the higher of the middle two is chosen

  - ### Method Detail

    - #### values

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

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

    - #### valueOf

          public static SortedSetSelector.Type 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
