li]$ddlmZGddZy)UnsupportedAggregationErrorc(eZdZdZdZdZdZdZy) Aggregationa Aggregations create a new value by summarizing a :class:`.Column`. Aggregations are applied with :meth:`.Table.aggregate` and :meth:`.TableSet.aggregate`. When creating a custom aggregation, ensure that the values returned by :meth:`.Aggregation.run` are of the type specified by :meth:`.Aggregation.get_aggregate_data_type`. This can be ensured by using the :meth:`.DataType.cast` method. See :class:`.Summary` for an example. c.|jjS)zq String representation of this column.
