/**
|
||
* @brief
|
||
* Interface for component which uses actions
|
||
*
|
||
* @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.
|
||
*
|
||
* The HasActionsIF allows components to define such actions and make them
|
||
* available for other components to use. Implementing the interface is
|
||
* straightforward: There’s 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.
|
||
*
