org.jdesktop.swingx.renderer.MappedValue

All Implemented Interfaces:

java.io.Serializable, BooleanValue, IconValue, StringValue

Direct Known Subclasses:

MappedValues.MappedValueUIResource

public class MappedValue
extends java.lang.Object
implements StringValue, IconValue, BooleanValue

Compound implementation of XXValue. Currently, XX stands for String, Icon, Boolean.

Quick hack around #590-swingx: LabelProvider should respect StringValue when formatting (instead of going clever with icons). Note: this will change!
