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

route

public <T> List<Invoker<T>> route(List<Invoker<T>> invokers,
                                  org.apache.dubbo.common.URL url,
                                  Invocation invocation)
                           throws RpcException

从接口复制的说明: Router

Filter invokers with current routing rule and only return the invokers that comply with the rule.

指定者:

route 在接口中 Router

参数:

invokers - invoker list

url - refer url

invocation - invocation

返回:

routed invokers

抛出:

RpcException

getPriority

public int getPriority()

从接口复制的说明: Router

Router's priority, used to sort routers.

指定者:

getPriority 在接口中 Router

覆盖:

getPriority 在类中 AbstractRouter

返回:

router's priority

isForce

public boolean isForce()

从接口复制的说明: Router

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

指定者:

isForce 在接口中 Router

覆盖:

isForce 在类中 AbstractRouter

返回:

true to execute if none of invokers matches the current router
