"""
Decorator used to register a scheduler to be returned by get_declared_schedulers().
Mandatory arguments :
name : the complete name of the scheduler (ex : simso.schedulers.EDF)
Optional keyword arguments :
display_name : name to be shown to the user
required_fields : list of required fields for this scheduler to work correctly.
It should be a dict with the following keys :
name: name of the field
type: type of the field
default: default value of the field
required_task_fields : list of required fields for this scheduler's tasks
to work correctly. Same format as required_fields
required_proc_fields : list of required fields for this scheduler's processors
to work correctly. Same format as required_fields
The list of registered schedulers is mostly used in graphical interfaces to auto-detect
the exposed schedulers.
