Class ExpandedConfigurationListenerAdapter

java.lang.Object
  com.netflix.config.ExpandedConfigurationListenerAdapter

All Implemented Interfaces:

org.apache.commons.configuration.event.ConfigurationListener

public class ExpandedConfigurationListenerAdapter
extends java.lang.Object
implements org.apache.commons.configuration.event.ConfigurationListener

An ExpandedConfigurationListenerAdapter wraps an instance of PropertyListener. When it receives the property modification notification from the Apache Configuration, it translates the ConfigurationEvent into the corresponding events for PropertyListener.

It also has the capability to pause the event delivery through the setPauseListener(boolean) API.

This class is used as an adapter to attach a PropertyListener to a Configuration so that methods in the PropertyListener will be called when there is a change in the configuration.
