Router chain

Method Summary

Modifier and Type	Method and Description
void	addRouters(List<Router> routers) If we use route:// protocol in version before 2.7.0, each URL will generate a Router instance, so we should keep the routers up to date, that is, each time router URLs changes, we should update the routers list, only keep the builtinRouters which are available all the time and the latest notified routers which are generated from URLs.
void	addStateRouters(List<StateRouter<T>> stateRouters)
static <T> RouterChain<T>	buildChain(Class<T> interfaceClass, org.apache.dubbo.common.URL url)
RouterSnapshotNode<T>	buildRouterSnapshot(org.apache.dubbo.common.URL url, BitList<Invoker<T>> availableInvokers, Invocation invocation) Build each router's result
void	destroy()
List<Router>	getRouters()
List<StateRouter<T>>	getStateRouters()
void	initWithRouters(List<Router> builtinRouters) the resident routers must being initialized before address notification.
void	initWithStateRouters(List<StateRouter<T>> builtinRouters) the resident routers must being initialized before address notification.
List<Invoker<T>>	route(org.apache.dubbo.common.URL url, BitList<Invoker<T>> availableInvokers, Invocation invocation)
void	setInvokers(BitList<Invoker<T>> invokers) Notify router chain of the initial addresses from registry at the first time.
