Enum FieldInfo.DocValuesType

java.lang.Object
java.lang.Enum<FieldInfo.DocValuesType>
org.apache.lucene.index.FieldInfo.DocValuesType
All Implemented Interfaces:
Serializable, Comparable<FieldInfo.DocValuesType>, java.lang.constant.Constable
Enclosing class:
FieldInfo
public static enum FieldInfo.DocValuesType extends Enum<FieldInfo.DocValuesType>
DocValues types. Note that DocValues is strongly typed, so a field cannot have different types across different documents.

  • Enum Constant Details

    • NUMERIC

      public static final FieldInfo.DocValuesType NUMERIC
      A per-document Number

    • BINARY

      public static final FieldInfo.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 FieldInfo.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 invalid input: '<'= 32766 bytes.

    • SORTED_SET

      public static final FieldInfo.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 invalid input: '<'= 32766 bytes.

  • Method Details

    • values

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

    • valueOf

      public static FieldInfo.DocValuesType 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
