org.apache.cassandra.db.composites.Composite
A composite value. This can be though as a list of ByteBuffer, except that this also include an 'end-of-component' flag, that allow precise selection of composite ranges. We also make a difference between "true" composites and the "simple" ones. The non-truly composite will have a size() == 1 but differs from true composites with size() == 1 in the way they are stored. Most code shouldn't have to care about the difference.
