Answer» The list of available hook points are given below: - pre_system: It is called initially during system execution.
- pre_controller: It is called immediately before any of the controllers being called. Example:

- post_controller: It is called immediately after the complete execution of the controller.
- display_override: It overrides the _display() method.
- cache_override: It ENABLES calling of the user-defined method instead of _display_cache() method which is available in the OUTPUT Library. This permits you for USING your own cache display mechanism.
