org.apache.dubbo.common.URL	getUrl() Get the router url.
boolean	isForce() 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.
boolean	isRuntime() To decide whether this router need to execute every time an RPC comes or should only execute when addresses or rule change.
<T> void	notify(List<Invoker<T>> invokers) Notify the router the invoker list.
void	process(ConfigChangeEvent event)
<T> List<Invoker<T>>	route(List<Invoker<T>> invokers, org.apache.dubbo.common.URL url, Invocation invocation) Filter invokers with current routing rule and only return the invokers that comply with the rule.

TagRouter

public TagRouter(DynamicConfiguration configuration,
                 org.apache.dubbo.common.URL url)

方法详细资料

process

public void process(ConfigChangeEvent event)

指定者:

process 在接口中 ConfigurationListener

getUrl

public org.apache.dubbo.common.URL getUrl()

从接口复制的说明: Router

Get the router url.

指定者:

getUrl 在接口中 Router

覆盖:

getUrl 在类中 AbstractRouter

返回:

url

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

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.

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

setApplication

public void setApplication(String app)

notify

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

从接口复制的说明: Router

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

指定者:

notify 在接口中 Router

类型参数:

T - invoker's type

参数:

invokers - invoker list
