Examples of com.netflix.config.ExpandedConfigurationListenerAdapter

com.netflix.config.ExpandedConfigurationListenerAdapter

An ExpandedConfigurationListenerAdapter wraps an instance of {@link PropertyListener}. When it receives the property modification notification from the Apache Configuration, it translates the {@link ConfigurationEvent} into the corresponding events for {@link PropertyListener}.
It also has the capability to pause the event delivery through the {@link #setPauseListener(boolean)} API.
This class is used as an adapter to attach a {@link PropertyListener} to a Configuration so thatmethods in the {@link PropertyListener} will be called when there is a change in the configuration.
