void	addListener(String key, String group, ConfigurationListener listener)	Register a configuration listener for a specified key The listener only works for service governance purpose, so the target group would always be the value user specifies at startup or 'dubbo' by default.
String	getRule(String key, String group, long timeout)	Get the governance rule mapped to the given key and the given group.
void	removeListener(String key, String group, ConfigurationListener listener)	Stops one listener from listening to value changes in the specified key.

addListener

public void addListener(String key,

                        ConfigurationListener listener)

从接口复制的说明: GovernanceRuleRepository

Register a configuration listener for a specified key The listener only works for service governance purpose, so the target group would always be the value user specifies at startup or 'dubbo' by default. This method will only register listener, which means it will not trigger a notification that contains the current value.

指定者:

addListener 在接口中 GovernanceRuleRepository

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: GovernanceRuleRepository

getRule

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

从接口复制的说明: GovernanceRuleRepository

指定者:

getRule 在接口中 GovernanceRuleRepository

参数:
