Description copied from class: BaseService

Services provide their services through the action(...) method. An implementation of a non-composite service like BaseService uses the action method to hook in the middle of the action routing and provide filtering, logging etc.

Overrides:

action in class BaseFilterService

Parameters:

path - The path of the component to whom the action is targeted.

input - The request data.

output - The response data.

Throws:

Exception - Any runtime exception that may occur.
