Arp::System::Acf Namespace Reference

This is the namespace of the Application Component Framework. More...

Classes
class	ComponentBase
	Use this class as base class for all Acf components. More...
class	ComponentFactory
	This class is used by Acf libraries to provide a component factory of the library specific components. More...
class	IApplication
	This interface shall be implemented by the application class. More...
class	IComponent
	This is the most important basic interface of the Arp platform. Any component shall implement this interface. The Acf will use this interface to load, set up and dispose components during system startup and shutdown, respectively. If the component has its own threads, it shall implement the IControllerComponent interface, to start and stop them. More...
class	IComponentFactory
	This interface is used by the Acf to create components dynamiically through configuration (.acf.config), and should be implemented by all component factories provided by an Acf library. More...
class	IControllerComponent
	This is a quite important interface of the Arp platform. This is an extension to the basic IComponent interface and shall be implemented by components having its own threads. The Acf will use this interface to start and stop components during system startup and shutdown, respectively. More...
class	ILibrary
	Any Acf Library shall implement this interface. More...
class	LibraryBase
	Any Acf Library shall derive from this base class. More...

Enumerations
enum class	ComponentCategory : uint8 { None = 0 , System = 1 , Service = 2 , Custom = 3 }
	This enumeration determines the category of a component. More...

Functions
ARP_CXX_SYMBOL_EXPORT std::ostream &	operator<< (std::ostream &os, ComponentCategory value)
ARP_CXX_SYMBOL_EXPORT std::istream &	operator>> (std::istream &is, ComponentCategory &value)

Detailed Description

This is the namespace of the Application Component Framework.

The Application Component Framework (Acf) is the basic infrastructure of the Arp platform to build applications, libraries and components. The main application will set up the basic infrastructure to load libraries and instantiate components dynamically through Acf configuration files (*.acf.config). Thus, the Acf builds the base of the Arp component based architecture.

Enumeration Type Documentation

ComponentCategory

enum Arp::System::Acf::ComponentCategory : uint8

strong

This enumeration determines the category of a component.

Enumerator
None	Not specified
System	System components used by the System, Device, Plc or Io domains. Components of this category are required by default.
Service	Service components used by Services domain (e.g. OpcUA, Ehmi, ProfiCLoud, Wbm, ..). Components of this category are not required by default.
Custom	Custom components implemented by customers. Components of this category are not required by default.
