public AbstractProtocol()

方法详细资料

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

refer

public <T> Invoker<T> refer(Class<T> type,
                            URL url)
                     throws RpcException

从接口复制的说明: Protocol

Refer a remote service:
1. When user calls `invoke()` method of `Invoker` object which's returned from `refer()` call, the protocol needs to correspondingly execute `invoke()` method of `Invoker` object
2. It's protocol's responsibility to implement `Invoker` which's returned from `refer()`. Generally speaking, protocol sends remote request in the `Invoker` implementation.
3. When there's check=false set in URL, the implementation must not throw exception but try to recover when connection fails.

指定者:

refer 在接口中 Protocol

类型参数:

T - Service type

参数:

type - Service class

url - URL address for the remote service

返回:

invoker service's local proxy

抛出:

RpcException - when there's any error while connecting to the service provider
