Examples of org.freehep.util.UserProperties

org.freehep.util.UserProperties
Special property class which allows typed properties to be set and returned. It also allows the hookup of two default property objects to be searched if this property object does not contain the property. FIXME check what org.freehep.application.PropertyUtilities.java has to offer and merge, or not FIXME: This class does not seem general enough to be a "public" utility. Should be improved and merged with PropertyUtilities, or moved into the graphicsio package (tonyj) @author Mark Donszelmann @version $Id: UserProperties.java 8584 2006-08-10 23:06:37Z duns $
