[docs]class Config(object):
'''
Configuration class which can be used to work with configuration parameters.
The class is designed to work with getters and setters, so you can easily
read / write config parameters by accessing the Config instance's
attributes. You can also add complete Python modules to the Config instance
by calling the add_module() method.
By default all ``ansibleci.defaults`` will be loaded, however you can
overwrite that in the constructor.
'''
def __init__(self, load_defaults=True):
'''
Class constructor which initializes the internal configuration dict.
By default the Config instance will load ``ansibleci.defaults``, though you
can supress that by setting ``load_defaults=False`` while creating the
Config instance.
