0001 # Services 0002 0003  0004 0005 Extension that helps to create services. Many extensions may need to behave like services or daemons, doing their tasks in the 0006 background, independently from UI. This extension helps to organize and coordinate them. 0007 0008 Services work on the basis of [The State Machine Framework](https://doc.qt.io/qt-6/qtstatemachine-cpp-guide.html). Each service is 0009 controlled by its own state machine. This state machine is composed of some standard, predefined states commonly referred as 0010 _state interface_. The details of actions performed in those state, as well as some of the transitions, are a subject of 0011 cutehmi::services::Serviceable implementation. 0012 0013  0014 0015 ## Major classes 0016 0017 Each object that wants to become a service either extends cutehmi::services::AbstractService or implements 0018 cutehmi::services::Serviceable interface. In order to turn object that implements cutehmi::services::Serviceable interface into a 0019 service one has to embed it inside cutehmi::services::Service object. 0020 0021 Class cutehmi::services::SelfService can be used to define the service in QML without the need of using C++ API. 0022 0023 Class cutehmi::services::ServiceGroup can be used to conveniently manage a group of services. 0024 0025 Service operations can be managed by controllers (descendants of cutehmi::services::AbstractServiceController) and group rules 0026 (descendants of cutehmi::services::ServiceGroupRule). 0027 0028 ## Related pages 0029 0030 - [CHANGES](CHANGES.md)
