class hestia_earth.calculation.assessment_hierarchies.Assessments_hierarchy

Bases: hestia_earth.calculation.abstract_hierarchy.Hierarchy

Assessments_hierarchy class. This is an abstract class from which inherit all the hierarchies defined in Hestia. It contains a set of common impacts and instance variables that are typically used by every hierarchy. A hierarchy defines the order to run the calculations of impacts in Hestia. The order is from higher tier to lower tier.

process_hierarchy(data)

Method that runs the hierarchy through all the impacts for a given cycle. :param cycle: This is a cycle in the representation required by the calculation engine. :param (Different from the Schema representation):

Returns a file object.

round_to_significant(number, sig_number)

Method to round to a given number of significant numbers. :param number: The number to round. :param sig_number: The number of significant numbers.

Returns The rounded number.

update_representation(cycle)

Method that checks if the model has enough data to do the calculation. :param cycle: This is a cycle in the representation required by the calculation engine. :param (Different from the Schema representation):

Returns boolean.
