      • register

        public void register(URL url)
        从接口复制的说明: RegistryService
        Register data, such as : provider service, consumer address, route rule, override rule and other data.

        Registering is required to support the contract:
        1. When the URL sets the check=false parameter. When the registration fails, the exception is not thrown and retried in the background. Otherwise, the exception will be thrown.
        2. When URL sets the dynamic=false parameter, it needs to be stored persistently, otherwise, it should be deleted automatically when the registrant has an abnormal exit.
        3. When the URL sets category=routers, it means classified storage, the default category is providers, and the data can be notified by the classified section.
        4. When the registry is restarted, network jitter, data can not be lost, including automatically deleting data from the broken line.
        5. Allow URLs which have the same URL but different parameters to coexist,they can't cover each other.

        指定者:
        register 在接口中 RegistryService
        覆盖:
        register 在类中 AbstractRegistry
        参数:
        url - Registration information , is not allowed to be empty, e.g: dubbo://10.20.153.10/com.alibaba.foo.BarService?version=1.0.0&application=kylin

      • unregister

        public void unregister(URL url)
        从接口复制的说明: RegistryService
        Unregister

        Unregistering is required to support the contract:
        1. If it is the persistent stored data of dynamic=false, the registration data can not be found, then the IllegalStateException is thrown, otherwise it is ignored.
        2. Unregister according to the full url match.

        指定者:
        unregister 在接口中 RegistryService
        覆盖:
        unregister 在类中 AbstractRegistry
        参数:
        url - Registration information , is not allowed to be empty, e.g: dubbo://10.20.153.10/com.alibaba.foo.BarService?version=1.0.0&application=kylin

      • subscribe

        public void subscribe(URL url,
                      NotifyListener listener)
        从接口复制的说明: RegistryService
        Subscrib to eligible registered data and automatically push when the registered data is changed.

        Subscribing need to support contracts:
        1. When the URL sets the check=false parameter. When the registration fails, the exception is not thrown and retried in the background.
        2. When URL sets category=routers, it only notifies the specified classification data. Multiple classifications are separated by commas, and allows asterisk to match, which indicates that all categorical data are subscribed.
        3. Allow interface, group, version, and classifier as a conditional query, e.g.: interface=com.alibaba.foo.BarService&version=1.0.0
        4. And the query conditions allow the asterisk to be matched, subscribe to all versions of all the packets of all interfaces, e.g. :interface=*&group=*&version=*&classifier=*
        5. When the registry is restarted and network jitter, it is necessary to automatically restore the subscription request.
        6. Allow URLs which have the same URL but different parameters to coexist,they can't cover each other.
        7. The subscription process must be blocked, when the first notice is finished and then returned.

        指定者:
        subscribe 在接口中 RegistryService
        覆盖:
        subscribe 在类中 AbstractRegistry
        参数:
        url - Subscription condition, not allowed to be empty, e.g. consumer://10.20.153.10/com.alibaba.foo.BarService?version=1.0.0&application=kylin
        listener - A listener of the change event, not allowed to be empty

      • unsubscribe

        public void unsubscribe(URL url,
                        NotifyListener listener)
        从接口复制的说明: RegistryService
        Unsubscribe

        Unsubscribing is required to support the contract:
        1. If don't subscribe, ignore it directly.
        2. Unsubscribe by full URL match.

        指定者:
        unsubscribe 在接口中 RegistryService
        覆盖:
        unsubscribe 在类中 AbstractRegistry
        参数:
        url - Subscription condition, not allowed to be empty, e.g. consumer://10.20.153.10/com.alibaba.foo.BarService?version=1.0.0&application=kylin
        listener - A listener of the change event, not allowed to be empty
