Examples of org.apache.tapestry.util.text.LocalizedProperties

org.apache.tapestry.util.text.LocalizedProperties
A version of java.util.Properties that can read the properties from files using an encoding other than ISO-8859-1. All non-latin characters are read correctly using the given encoding and no longer need to be quoted using native2ascii. In addition, the properties may be stored in an arbitrary map, rather than only in Properties. For example, using LinkedHashMap will preserve the order of the properties as defined in the file. @author mb @since 4.0
