Examples of org.apache.cassandra.thrift.SlicePredicate$SlicePredicateTupleScheme

org.apache.cassandra.thrift.SlicePredicate
kipedia.org/wiki/Predicate_(mathematical_logic)), which is described as "a property that the elements of a set have in common." SlicePredicate's in Cassandra are described with either a list of column_names or a SliceRange. If column_names is specified, slice_range is ignored. @param column_name. A list of column names to retrieve. This can be used similar to Memcached's "multi-get" featureto fetch N known column names. For instance, if you know you wish to fetch columns 'Joe', 'Jack', and 'Jim' you can pass those column names as a list to fetch all three at once. @param slice_range. A SliceRange describing how to range, order, and/or limit the slice.
