Examples of DynamicConfiguration

com.netflix.config.DynamicConfiguration
A configuration that polls a {@link PolledConfigurationSource} according to the schedule set by ascheduler. The property values in this configuration will be changed dynamically at runtime if the value changes in the configuration source.
This configuration does not allow null as key or value and will throw NullPointerException when trying to add or set properties with empty key or value. @author awang
org.glassfish.hk2.api.DynamicConfiguration
This class is used to add {@link Descriptor}s to a {@link ServiceLocator}instance. No operation performed on this object will be reflected in the {@link ServiceLocator} until the commit method is called. @author jwells
org.rioproject.impl.config.DynamicConfiguration
The class represents a configuration object that can be populated with entries programmatically at runtime.
