All Implemented Interfaces:

Comparable<StateRouter<T>>, StateRouter<T>

public class MockInvokersSelector<T>
extends AbstractStateRouter<T>

A specific Router designed to realize mock feature. If a request is configured to use mock, then this router guarantees that only the invokers with protocol MOCK appear in final the invoker list, all other invokers will be excluded.

Description copied from interface: StateRouter

** This method can return the state of whether routerChain needed to continue route. ** Filter invokers with current routing rule and only return the invokers that comply with the rule. Caching address lists in BitMap mode improves routing performance.

Parameters:

invokers - invoker bit list

url - refer url

invocation - invocation

needToPrintMessage - whether to print router state. Such as `use router branch a`.

Returns:

state with route result

Throws:

RpcException

notify

public void notify(BitList<Invoker<T>> invokers)

Description copied from interface: StateRouter

Notify the router the invoker list. Invoker list may change from time to time. This method gives the router a chance to prepare before StateRouter.route(BitList, URL, Invocation, boolean) gets called.

Specified by:

notify in interface StateRouter<T>

Overrides:

notify in class AbstractStateRouter<T>

Parameters:

invokers - invoker list
