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

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.

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
