StringValue provides an implementation of the Value interface representing a string value.
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
A {@link PrimitiveValue} corresponding to the Java type {@link String}.
@author Daniel Meyer @since 7.2ComponentProvider. F.i. to show a Contributor cell object as "Busywoman, Herta" implement a custom StringValue and use it in a text rendering provider.
StringValue stringValue = new StringValue() { public String getString(Object value) { if (!(value instanceof Contributor)) return TO_STRING.getString(value); Contributor contributor = (Contributor) value; return contributor.lastName + ", " + contributor.firstName; } }; ComponentProvider provider = new LabelProvider(stringValue); table.setDefaultRenderer(Contributor.class, new DefaultTableRenderer(provider)); PENDING: use a full-fledged Format instead? Would impose a higher burden onto implementors but could be re-used in editors. @author Jeanette Winzenburg @see ComponentProvider @see LabelProvider @see DefaultTableRenderer @see DefaultListRenderer @see DefaultTreeRenderer
