- - ### Field Detail

    - #### clusteringType

          protected final CompoundCType clusteringType

    - #### fullType

          protected final CompoundCType fullType

    - #### clusteringSize

          protected final int clusteringSize

    - #### fullSize

          protected final int fullSize

  - ### Constructor Detail

    - #### AbstractCompoundCellNameType

          protected AbstractCompoundCellNameType(CompoundCType clusteringType,
                                                 CompoundCType fullType)

  - ### Method Detail

    - #### clusteringPrefixSize

          public int clusteringPrefixSize()

      Description copied from interface: `CellNameType`
      The number of clustering columns for the table this is the type of.

    - #### isCompound

          public boolean isCompound()

      Description copied from interface: `CType`
      Returns whether this is a "truly-composite" underneath.

    - #### size

          public int size()

      Description copied from interface: `CType`
      The number of subtypes for this CType.

    - #### subtype

          public AbstractType<?> subtype(int i)

      Description copied from interface: `CType`
      Gets a subtype of this CType.

    - #### prefixBuilder

          public CBuilder prefixBuilder()

      Description copied from interface: `CellNameType`
      A builder for the clustering prefix.

    - #### builder

          public CBuilder builder()

      Description copied from interface: `CType`
      A builder of Composite.

    - #### fromByteBuffer

          public Composite fromByteBuffer(java.nio.ByteBuffer bytes)

      Description copied from interface: `CType`
      Deserialize a Composite from a ByteBuffer. This is meant for thrift to convert the fully serialized buffer we get from the clients to composites.

    - #### asAbstractType

          public AbstractType<?> asAbstractType()

      Description copied from interface: `CType`
      Returns a AbstractType corresponding to this CType for thrift sake. If the CType is a "simple" one, this just return the wrapped type, otherwise it returns the corresponding org.apache.cassandra.db.marshal.CompositeType. This is only meant to be use for backward compatibility (particularly for thrift) but it's not meant to be used internally.

    - #### newDeserializer

          public CellNameType.Deserializer newDeserializer(java.io.DataInput in)

      Description copied from interface: `CellNameType`
      Creates a new Deserializer. This is used by AtomDeserializer to do incremental and on-demand deserialization of the on disk atoms. See AtomDeserializer for details.

    - #### makeCellName

          protected CellName makeCellName(java.nio.ByteBuffer[] components)

      Specified by:
        `makeCellName` in class `AbstractCellNameType`

    - #### makeWith

          protected abstract Composite makeWith(java.nio.ByteBuffer[] components,
                                                int size,
                                                Composite.EOC eoc,
                                                boolean isStatic)

    - #### copyAndMakeWith

          protected abstract Composite copyAndMakeWith(java.nio.ByteBuffer[] components,
                                                       int size,
                                                       Composite.EOC eoc,
