Examples of org.apache.cassandra.thrift.ColumnPath$ColumnPathStandardScheme

org.apache.cassandra.thrift.ColumnPath
The ColumnPath is the path to a single column in Cassandra. It might make sense to think of ColumnPath and ColumnParent in terms of a directory structure. ColumnPath is used to looking up a single column. @param column_family. The name of the CF of the column being looked up. @param super_column. The super column name. @param column. The column name.

            public Map<ByteBuffer, SuperColumn> execute(KeyspaceService keyspace) {
