/**
* @brief
* Interface for component which uses actions
2018-07-13 18:28:26 +02:00
*
* @details
* This interface is used to execute actions in the component. Actions, in the
* sense of this interface, are activities with a well-defined beginning and
* end in time. They may adjust sub-states of components, but are not supposed
* to change the main mode of operation, which is handled with the HasModesIF
* described below.
2018-07-13 18:28:26 +02:00
*
* The HasActionsIF allows components to define such actions and make them
* available for other components to use. Implementing the interface is
* straightforward: Theres a single executeAction call, which provides an
* identifier for the action to execute, as well as arbitrary parameters for
* input.
* Aside from direct, software-based actions, it is used in device handler
* components as an interface to forward commands to devices.
* Implementing components of the interface are supposed to check identifier
* (ID) and parameters and immediately start execution of the action.
* It is, however, not required to immediately finish execution.
* Instead, this may be deferred to a later point in time, at which the
* component needs to inform the caller about finished or failed execution.
*
* @ingroup interfaces
