方法详细资料

getInternalProperty

public Object getInternalProperty(String key)

指定者:

getInternalProperty 在接口中 Configuration

参数:

key - e.g., {service}.configurators, {service}.tagrouters, {group}.dubbo.properties

返回:

addListener

public void addListener(String key,
                        String group,
                        ConfigurationListener listener)

For service governance, multi group is not supported by this implementation. So group is not used at present.

指定者:

addListener 在接口中 DynamicConfiguration

参数:

key - the key to represent a configuration

group - the group where the key belongs to

listener - configuration listener

removeListener

public void removeListener(String key,
                           String group,
                           ConfigurationListener listener)

从接口复制的说明: DynamicConfiguration

Stops one listener from listening to value changes in the specified key.

指定者:

removeListener 在接口中 DynamicConfiguration

参数:

key - the key to represent a configuration

group - the group where the key belongs to

listener - configuration listener

getConfig

public String getConfig(String key,
                        String group,
                        long timeout)
                 throws IllegalStateException

从接口复制的说明: DynamicConfiguration

Get the configuration mapped to the given key and the given group. If the configuration fails to fetch after timeout exceeds, IllegalStateException will be thrown.

指定者:

getConfig 在接口中 DynamicConfiguration

参数:

key - the key to represent a configuration

group - the group where the key belongs to

timeout - timeout value for fetching the target config

返回:

target configuration mapped to the given key and the given group, IllegalStateException will be thrown if timeout exceeds.

抛出:

IllegalStateException

getConfigs

public String getConfigs(String key,
                         String group,
                         long timeout)
                  throws IllegalStateException

For zookeeper, getConfig(String, String, long) and getConfigs(String, String, long) have the same meaning.

指定者:

getConfigs 在接口中 DynamicConfiguration

参数:

key -

group -

timeout -

返回:

抛出:

IllegalStateException
