方法详细资料

getDubboProtocol

public static DubboProtocol getDubboProtocol()

getInvokers

public Collection<Invoker<?>> getInvokers()

getDefaultPort

public int getDefaultPort()

从接口复制的说明: Protocol

Get default port when user doesn't config the port.

返回:

default port

export

public <T> Exporter<T> export(Invoker<T> invoker)
                       throws RpcException

从接口复制的说明: Protocol

Export service for remote invocation:
1. Protocol should record request source address after receive a request: RpcContext.getContext().setRemoteAddress();
2. export() must be idempotent, that is, there's no difference between invoking once and invoking twice when export the same URL
3. Invoker instance is passed in by the framework, protocol needs not to care

类型参数:

T - Service type

参数:

invoker - Service invoker

返回:

exporter reference for exported service, useful for unexport the service later

抛出:

RpcException - thrown when error occurs during export the service, for example: port is occupied

protocolBindingRefer

public <T> Invoker<T> protocolBindingRefer(Class<T> serviceType,
                                           URL url)
                                    throws RpcException

抛出:

RpcException

destroy

public void destroy()

从接口复制的说明: Protocol

Destroy protocol:
1. Cancel all services this protocol exports and refers
2. Release all occupied resources, for example: connection, port, etc.
3. Protocol can continue to export and refer new service even after it's destroyed.

指定者:

destroy 在接口中 Protocol

覆盖:

destroy 在类中 AbstractProtocol
