Detailed Description
The TypeRegistry allows registration of type instance creation functions.
These can then be created later by name and down cast to the appropriate type.
Usage: (Registering)
In my-actor.cpp
// Note: object construction in namespace scope is defined in a translation unit as being // in appearance order (C++ standard 3.6/2). So TypeRegistration is declared first in // the cpp file below. Signal, action and property declarations follow in any order. namespace { TypeRegistration myActorType(typeid(MyActor), typeid(Actor), CreateMyActor ); SignalConnectorType( myActorType, "highlighted", ConnectSignalForMyActor ); TypeAction( myActorType, "open", DoMyActorAction ); TypeAction( myActorType, "close", DoMyActorAction ); PropertyRegistration( myActorType, "status", PropertyRegistration::START_INDEX, Property::BOOLEAN, SetPropertyFunction, GetPropertyFunction ); }
Usage: (Creation)
TypeRegistry::TypeInfo type = TypeRegistry::Get().GetTypeInfo("MyActor"); MyActor a = MyActor::DownCast(type.CreateInstance()); if(a) { ... }
Actors that inherit from the CustomActor framework must ensure the implementation class has an identical name to the Actor class. This is to ensure the class can be found at runtime for signals and actions. Otherwise these will silently fail.
As namespaces are discarded the convention is to use a namespace ie
'class MyActor {}; namespace Internal { class MyActor {}; }'
Warning: this arrangement will silently fail
'class MyActor {}; class MyActorImpl {};'
Naming Conventions
Signal and action names follow properties and are by convention lower case hyphen separated ie 'next-page'. This maintains consistency with the scripted interface.
