PropertiesContainer

class PropertiesContainer

Bases: MutableSet

The properties container class.

This class manages storage of Property objects. These objects are operator factories, generating the aux_operators that will be passed down to quantum algorithms which support their evaluation.

This container class can only contain a single instance of any Property kind. It enforces this via a MutableSet implementation.

isdisjoint(other)

Return True if two sets have a null intersection.

pop()
