# Enum Class DocValuesType

java.lang.Object
java.lang.Enum<DocValuesType>
org.apache.lucene.index.DocValuesType

All Implemented Interfaces:
  `Serializable`, `Comparable<DocValuesType>`, `Constable`

public enum DocValuesType extends Enum<DocValuesType>
DocValues types. Note that DocValues is strongly typed, so a field cannot have different types across different documents.

  Modifier and Type
  Method
  Description
  `static DocValuesType`
  `valueOf(String name)`
  Returns the enum constant of this class with the specified name.
  `static DocValuesType[]`
  `values()`
  Returns an array containing the constants of this enum class, in the order they are declared.

- ## Enum Constant Details

  - ### NONE

    public static final DocValuesType NONE
    No doc values for this field.

  - ### NUMERIC

    public static final DocValuesType NUMERIC
    A per-document Number

  - ### BINARY

    public static final DocValuesType BINARY
    A per-document byte[]. Values may be larger than 32766 bytes, but different codecs may enforce their own limits.

  - ### SORTED

    public static final DocValuesType SORTED
    A pre-sorted byte[]. Fields with this type only store distinct byte values and store an additional offset pointer per document to dereference the shared byte[]. The stored byte[] is presorted and allows access via document id, ordinal and by-value. Values must be `<= 32766` bytes.

  - ### SORTED_NUMERIC

    public static final DocValuesType SORTED_NUMERIC
    A pre-sorted Number[]. Fields with this type store numeric values in sorted order according to `Long.compare(long, long)`.

  - ### SORTED_SET

    public static final DocValuesType SORTED_SET
    A pre-sorted Set<byte[]>. Fields with this type only store distinct byte values and store additional offset pointers per document to dereference the shared byte[]s. The stored byte[] is presorted and allows access via document id, ordinal and by-value. Values must be `<= 32766` bytes.

- ## Method Details

  - ### values

    public static DocValuesType[] values()
    Returns an array containing the constants of this enum class, in the order they are declared.
    Returns:
      an array containing the constants of this enum class, in the order they are declared

  - ### valueOf

    public static DocValuesType valueOf(String name)
    Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name
      `NullPointerException` - if the argument is null
