Class SystemPropertiesConfiguration

java.lang.Object

org.apache.commons.configuration.event.EventSource

org.apache.commons.configuration.AbstractConfiguration

org.overlord.commons.config.SystemPropertiesConfiguration

All Implemented Interfaces:

org.apache.commons.configuration.Configuration

public class SystemPropertiesConfiguration
extends org.apache.commons.configuration.AbstractConfiguration

A Configuration implementation based on the current java system properties. This implementation differs from SystemConfiguration because it pulls the system properties live, rather than caching them when the configuration instance is created. This allows configuration to change by modifying the system properties at runtime.
