"""
This module contains the ActionManager class which belongs to the Agent class.
An agent's action space is made up of a collection of actions. Each action is an instance of a subclass of
AbstractAction. The ActionManager is responsible for:
1. Creating the action space from a list of action types.
2. Converting an integer action choice into a specific action and parameter choice.
3. Converting an action and parameter choice into a request which can be ingested by the PrimAITE simulation. This
ensures that requests conform to the simulator's request format.

Each action component has a ``type`` which maps to a subclass of AbstractAction, and additional options
which will be passed to the action class's __init__ method during initialisation.
2. ``action_map``
Since the agent uses a discrete action space which acts as a flattened version of the component-based
action space, action_map provides a mapping between an integer (chosen by the agent) and a meaningful
action and values of parameters. For example action 0 can correspond to do nothing, action 1 can
correspond to "NODE_SERVICE_SCAN" with ``node_id=1`` and ``service_id=1``, action 2 can be "
3. ``options``
``options`` contains a dictionary of options which are passed to the ActionManager's __init__ method.

to the ActionManager which is required to convert the agent's action choice into a CAOS request.
