修饰符和类型	方法	说明
String	buildSnapshot()	Build Router's Current State Snapshot for QoS
StateRouter<T>	getNextRouter()
GovernanceRuleRepository	getRuleRepository()
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 StateRouter.route(BitList, URL, Invocation, boolean, Holder) 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.
void	notify(BitList<Invoker<T>> invokers)	Notify the router the invoker list.
BitList<Invoker<T>>	route(BitList<Invoker<T>> invokers, org.apache.dubbo.common.URL url, Invocation invocation, boolean needToPrintMessage, org.apache.dubbo.common.utils.Holder<RouterSnapshotNode<T>> nodeHolder)	Filter invokers with current routing rule and only return the invokers that comply with the rule.
void	setForce(boolean force)
void	setNextRouter(StateRouter<T> nextRouter)	Next Router node state is maintained by AbstractStateRouter and this method is not allow to override.

构造器详细资料

AbstractStateRouter

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

方法详细资料

getUrl

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

从接口复制的说明: StateRouter

Get the router url.

指定者:

getUrl 在接口中 StateRouter<T>

返回:

url

setUrl

public void setUrl(org.apache.dubbo.common.URL url)

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>

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>

返回:

true to execute if none of invokers matches the current router

setForce

public void setForce(boolean force)

getRuleRepository

public GovernanceRuleRepository getRuleRepository()

getNextRouter

public StateRouter<T> getNextRouter()

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>

参数:

invokers - invoker list

route

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

从接口复制的说明: StateRouter

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.

指定者:

route 在接口中 StateRouter<T>

参数:

invokers - invoker bit list

url - refer url

invocation - invocation

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

返回:

state with route result

抛出:

RpcException

setNextRouter

public final void setNextRouter(StateRouter<T> nextRouter)

Next Router node state is maintained by AbstractStateRouter and this method is not allow to override. If a specified router wants to control the behaviour of continue route or not, please override supportContinueRoute()

指定者:

setNextRouter 在接口中 StateRouter<T>

参数:

nextRouter - next router node

buildSnapshot

public final String buildSnapshot()

从接口复制的说明: StateRouter

Build Router's Current State Snapshot for QoS

指定者:

buildSnapshot 在接口中 StateRouter<T>

返回:

Current State
