TagStateRouter

public TagStateRouter(org.apache.dubbo.common.URL url)

方法详细资料

process

public void process(org.apache.dubbo.common.config.configcenter.ConfigChangedEvent event)

指定者:

process 在接口中 org.apache.dubbo.common.config.configcenter.ConfigurationListener

doRoute

public BitList<Invoker<T>> doRoute(BitList<Invoker<T>> invokers,
                                   org.apache.dubbo.common.URL url,
                                   Invocation invocation,
                                   boolean needToPrintMessage,
                                   org.apache.dubbo.common.utils.Holder<RouterSnapshotNode<T>> nodeHolder,
                                   org.apache.dubbo.common.utils.Holder<String> messageHolder)
                            throws RpcException

抛出:

RpcException

isRuntime

public boolean isRuntime()

从接口复制的说明: StateRouter

To decide whether this router need to execute every time an RPC comes or should only execute when addresses or rule change.

指定者:

isRuntime 在接口中 StateRouter<T>

覆盖:

isRuntime 在类中 AbstractStateRouter<T>

返回:

true if the router need to execute every time.

isForce

public boolean isForce()

从接口复制的说明: StateRouter

To decide whether this router should take effect when none of the invoker can match the router rule, which means the StateRouter.route(BitList, URL, Invocation, boolean, Holder) would be empty. Most of time, most router implementation would default this value to false.

指定者:

isForce 在接口中 StateRouter<T>

覆盖:

isForce 在类中 AbstractStateRouter<T>

返回:

true to execute if none of invokers matches the current router

setApplication

public void setApplication(String app)

notify

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

从接口复制的说明: 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, Holder) gets called. No need to notify next node.

指定者:

notify 在接口中 StateRouter<T>

覆盖:

notify 在类中 AbstractStateRouter<T>

参数:

invokers - invoker list

stop

public void stop()

指定者:

stop 在接口中 StateRouter<T>
