## org.apache.cassandra.thrift
Class SlicePredicate

    java.lang.Object
      org.apache.cassandra.thrift.SlicePredicate

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

    public class SlicePredicate

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

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.
