Examples of org.apache.wicket.util.string.StringValue

org.apache.wicket.util.string.StringValue
Holds an immutable String value and optionally a Locale, with methods to convert to various types. Also provides some handy parsing methods and a variety of static factory methods.
Objects can be constructed directly from Strings or by using the valueOf() static factory methods. The repeat() static factory methods provide a way of generating a String value that repeats a given char or String a number of times.
Conversions to a wide variety of types can be found in the to*() methods. A generic conversion can be achieved with to(Class).
The beforeFirst(), afterFirst(), beforeLast() and afterLast() methods are handy for parsing things like paths and filenames. @author Jonathan Locke
