Class SlicePredicate

java.lang.Object
  extended by org.apache.cassandra.thrift.SlicePredicate
All Implemented Interfaces:
java.io.Serializable, java.lang.Cloneable, java.lang.Comparable<SlicePredicate>, org.apache.thrift.TBase<SlicePredicate,SlicePredicate._Fields>

public class SlicePredicate
extends java.lang.Object
implements org.apache.thrift.TBase<SlicePredicate,SlicePredicate._Fields>, java.io.Serializable, java.lang.Cloneable

A SlicePredicate is similar to a mathematic predicate (see http://en.wikipedia.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.
