Class ColumnOrSuperColumn

java.lang.Object

org.apache.cassandra.thrift.ColumnOrSuperColumn

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Comparable<ColumnOrSuperColumn>, org.apache.thrift.TBase<ColumnOrSuperColumn,ColumnOrSuperColumn._Fields>

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

Methods for fetching rows/records from Cassandra will return either a single instance of ColumnOrSuperColumn or a list of ColumnOrSuperColumns (get_slice()). If you're looking up a SuperColumn (or list of SuperColumns) then the resulting instances of ColumnOrSuperColumn will have the requested SuperColumn in the attribute super_column. For queries resulting in Columns, those values will be in the attribute column. This change was made between 0.3 and 0.4 to standardize on single query methods that may return either a SuperColumn or Column. If the query was on a counter column family, you will either get a counter_column (instead of a column) or a counter_super_column (instead of a super_column)
