                         Version version)
                  throws java.io.IOException

      Serialize given metadata components
      Parameters:
        `components` - Metadata components to serialize
        `out` -
        `version` -
      Throws:
        `java.io.IOException`

    - #### deserialize

          java.util.Map<MetadataType,MetadataComponent> deserialize(Descriptor descriptor,
                                                                    java.util.EnumSet<MetadataType> types)
                                                             throws java.io.IOException

      Deserialize specified metadata components from given descriptor.
      Parameters:
        `descriptor` - SSTable descriptor
      Returns:
        Deserialized metadata components, in deserialized order.
      Throws:
        `java.io.IOException`

    - #### deserialize

          MetadataComponent deserialize(Descriptor descriptor,
                                        MetadataType type)
                                 throws java.io.IOException

      Deserialized only metadata component specified from given descriptor.
      Parameters:
        `descriptor` - SSTable descriptor
        `type` - Metadata component type to deserialize
      Returns:
        Deserialized metadata component. Can be null if specified type does not exist.
      Throws:
        `java.io.IOException`

    - #### mutateLevel
