org.apache.dubbo.common.config.configcenter.TreePathDynamicConfiguration

所有已实现的接口:

AutoCloseable, DynamicConfiguration, Configuration

直接已知子类:

FileSystemDynamicConfiguration

public abstract class TreePathDynamicConfiguration
extends AbstractDynamicConfiguration

An abstract implementation of DynamicConfiguration is like "tree-structure" path :

• "file"
• "zookeeper"
• "consul"

方法概要

修饰符和类型	方法	说明
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.
SortedSet<String>	getConfigKeys(String group)	Get the config keys by the specified group
boolean	publishConfig(String key, String group, String content)	Publish Config 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.

TreePathDynamicConfiguration

public TreePathDynamicConfiguration(String rootPath,
                                    String threadPoolPrefixName,
                                    int threadPoolSize,

方法详细资料

publishConfig

public final boolean publishConfig(String key,
                                   String group,
                                   String content)

从接口复制的说明: DynamicConfiguration

Publish Config mapped to the given key and the given group.

参数:

key - the key to represent a configuration

group - the group where the key belongs to

content - the content of configuration

返回:

true if success, or false

addListener

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

从接口复制的说明: DynamicConfiguration

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 DynamicConfiguration

覆盖:

addListener 在类中 AbstractDynamicConfiguration

参数:

key - the key to represent a configuration

group - the group where the key belongs to

listener - configuration listener

removeListener

public final 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

覆盖:

removeListener 在类中 AbstractDynamicConfiguration

参数:

key - the key to represent a configuration

group - the group where the key belongs to

listener - configuration listener

getConfigKeys

public final SortedSet<String> getConfigKeys(String group)
                                      throws UnsupportedOperationException

从接口复制的说明: DynamicConfiguration

Get the config keys by the specified group

参数:

group - the specified group

返回:

the read-only non-null sorted set of config keys

抛出:

UnsupportedOperationException - If the under layer does not support
