public void init(String rule)

route

public <T> List<Invoker<T>> route(List<Invoker<T>> invokers,
                                  org.apache.dubbo.common.URL url,

                           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.

参数:

invokers - invoker list

url - refer url

invocation - invocation

返回:

routed invokers

抛出:

RpcException

isRuntime

public boolean isRuntime()

从接口复制的说明: Router

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 Router

覆盖:

isRuntime 在类中 AbstractRouter

返回:

true if the router need to execute every time.

matchArguments

public boolean matchArguments(Map.Entry<String,org.apache.dubbo.rpc.cluster.router.condition.ConditionRouter.MatchPair> matchPair,
                              Invocation invocation)

analysis the arguments in the rule. Examples would be like this: "arguments[0]=1", whenCondition is that the first argument is equal to '1'. "arguments[1]=a", whenCondition is that the second argument is equal to 'a'.

参数:

matchPair -

invocation -

返回:
