Klasse FWPropertyProvider

java.lang.Object
net.simplace.core.property.FWPropertyProvider
public final class FWPropertyProvider extends Object
Provider for properties. It centralizes access to properties throughout the whole application. In addition to making direct access to property files obsolete it also caches whole sets of properties (i.e. property files) by keeping them in memory. A property set is loaded into memory when any of the properties contained in it is being accessed for the first time.
