public class SystemPropertyModule
extends AbstractJXPathModule
implements ThreadSafe

SystemPropertyModule is an JXPath based InputModule implementation that provides access to system properties. Available system properties are defined by Java's System.getProperties(). JXPath allows to apply XPath functions to system properties.

If there is a security manager, its checkPropertiesAccess method is called with no arguments. This may result in a security exception which is wrapped into a configuration exception and re-thrown.
