from AthenaConfiguration import ComponentAccumulator class MyComponent: def __init__(self): self.services = ComponentAccumulator() def add_service(self, service_name, service_object): self.services.addService(service_name, service_object) def get_services(self): return self.services.getServices()In this example, we create a new component class called MyComponent. We initialize a ComponentAccumulator object in the constructor and add a method called add_service that uses the addService method to add a service to the accumulator. Finally, we define a method called get_services that returns all of the services accumulated by the accumulator. The AthenaConfiguration package library is a package used in the ATLAS experiment at CERN. It is used to configure and manage the software components used in the experiment.
