Inheritance diagram for score::InterfaceBase:

Detailed Description

Base class for plug-in interfaces.

The plug-in interfaces in score are organized as follows :

• Each base interface should inherit from Interface<MyInterface>
• There is a key type to identify each interface type : score::InterfaceKey
• Then, each implementation of each interface should itself provide a key to identify itself with regards to the other implementations.

This then allows to :

• Fetch a specific interface from an score::ApplicationContext :

// First get the interface list we are looking for, for instance
// the list of all process factories interface :
score::ApplicationContext& context = ...;
auto& iface_list = context.interfaces<MyInterfaceList>();

• Then look for the actual factory we want, obtained from user input for instance :

auto iface = iface_list.get(actual_factory_key);
 
// If iface is != nullptr, it means that we have a concrete factory to build
// a specific kind of process.

The actual hierarchy looks like :

InterfaceBase <- MyInterface    <- MyImplementation
              <- OtherInterface <- OtherImplementation1
                                <- OtherImplementation2
