__call__(data, dropna=False)

Call self as a function.

Computes difference between functor called on two different DataFrame/Handle objects

multilevelColumns(data, columnIndex=None, returnTuple=False)

Returns columns needed by functor from multilevel dataset

To access tables with multilevel column structure, the DeferredDatasetHandle or InMemoryDatasetHandle need to be passed either a list of tuples or a dictionary.

Parameters:
datavarious

The data as either DeferredDatasetHandle, or InMemoryDatasetHandle.

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 by CompositeFunctor in order to be able to combine columns from the various component functors.
