类 DubboProtocol

    • 构造器详细资料

      • DubboProtocol

        public DubboProtocol()

    • 方法详细资料

      • getDubboProtocol

        public static DubboProtocol getDubboProtocol()

      • 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> serviceType,
                            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:
        serviceType - 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

      • 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
