## Enum ColumnSerializer.Flag

- java.lang.Object
- - java.lang.Enum<ColumnSerializer.Flag>
  - - org.apache.cassandra.db.ColumnSerializer.Flag

- All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<ColumnSerializer.Flag>
  Enclosing class:
    ColumnSerializer

      public static enum ColumnSerializer.Flag
      extends java.lang.Enum<ColumnSerializer.Flag>

  Flag affecting deserialization behavior. - LOCAL: for deserialization of local data (Expired columns are converted to tombstones (to gain disk space)). - FROM_REMOTE: for deserialization of data received from remote hosts (Expired columns are converted to tombstone and counters have their delta cleared) - PRESERVE_SIZE: used when no transformation must be performed, i.e, when we must ensure that deserializing and reserializing the result yield the exact same bytes. Streaming uses this.

    - #### LOCAL

          public static final ColumnSerializer.Flag LOCAL

    - #### FROM_REMOTE

          public static final ColumnSerializer.Flag FROM_REMOTE

    - #### PRESERVE_SIZE

          public static final ColumnSerializer.Flag PRESERVE_SIZE

  - ### Method Detail

    - #### values

          public static ColumnSerializer.Flag[] 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 (ColumnSerializer.Flag c : ColumnSerializer.Flag.values())
              System.out.println(c);

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

    - #### valueOf

          public static ColumnSerializer.Flag valueOf(java.lang.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:
        `java.lang.IllegalArgumentException` - if this enum type has no constant with the specified name
        `java.lang.NullPointerException` - if the argument is null
