multilevelColumns
(data, columnIndex=None, returnTuple=False)¶ Returns columns needed by functor from multilevel dataset
To access tables with multilevel column structure, the
MultilevelParquetTable
orDeferredDatasetHandle
need to be passed either a list of tuples or a dictionary.Parameters: - data :
MultilevelParquetTable
orDeferredDatasetHandle
- columnIndex (optional): pandas `Index` object
either passed or read in from
DeferredDatasetHandle
.- `returnTuple` : bool
If true, then return a list of tuples rather than the column dictionary specification. This is set to
True
byCompositeFunctor
in order to be able to combine columns from the various component functors.
