atoti.hierarchy module

class atoti.hierarchy.Hierarchy(_name, _levels, _dimension, _slicing, _cube, _java_api, _visible)

Bases: atoti._base._base_hierarchy.BaseHierarchy[Mapping[str, atoti.level.Level]]

Hierarchy of a Cube.

property dimension

Name of the dimension of the hierarchy.

Return type

str

isin(*member_paths)

Return a condition to check that the hierarchy is on one of the given members.

Considering hierarchy_1 containing level_1 and level_2, hierarchy_1.isin((a,), (b, x)) is equivalent to (level_1 == a) OR ((level_1 == b) AND (level_2 == x)).

Parameters

members – One or more members expressed as tuples on which the hierarchy should be. Each element in a tuple corresponds to a level of the hierarchy, from the shallowest to the deepest.

Example

>>> df = pd.DataFrame(
...     columns=["Country", "City", "Price"],
...     data=[
...         ("Germany", "Berlin", 150.0),
...         ("Germany", "Hamburg", 120.0),
...         ("United Kingdom", "London", 240.0),
...         ("United States", "New York", 270.0),
...         ("France", "Paris", 200.0),
...     ],
... )
>>> store = session.read_pandas(
...     df, keys=["Country", "City"], store_name="isin example"
... )
>>> cube = session.create_cube(store)
>>> h, lvl, m = cube.hierarchies, cube.levels, cube.measures
>>> h["Geography"] = [lvl["Country"], lvl["City"]]
>>> m["Price.SUM in Germany and Paris"] = tt.filter(
...     m["Price.SUM"],
...     h["Geography"].isin(("Germany",), ("France", "Paris")),
... )
>>> cube.query(
...     m["Price.SUM"],
...     m["Price.SUM in Germany and Paris"],
...     levels=lvl["Geography", "City"],
... )
                        Price.SUM Price.SUM in Germany and Paris
Country        City
France         Paris       200.00                         200.00

               Hamburg     120.00                         120.00
United Kingdom London      240.00
United States  New York    270.00
