atoti.Level

final class atoti.Level

Level of a Hierarchy.

A level is a sub category of a hierarchy. Levels have a specific order with a parent-child relationship.

In a Pivot Table, a single-level hierarchy will be displayed as a flat attribute while a multi-level hierarchy will display the first level and allow users to expand each member against the next level and display sub totals.

For example, a Geography hierarchy can have a Continent as the top level where Continent expands to Country which in turn expands to the leaf level: City.
