org.apache.struts.util
Class LabelValueBean  

java.lang.Object
  org.apache.struts.util.LabelValueBean

All Implemented Interfaces:

java.lang.Comparable, java.io.Serializable

---

public class LabelValueBean

extends java.lang.Object

implements java.lang.Comparable, java.io.Serializable

A simple JavaBean to represent label-value pairs. This is most commonly used when constructing user interface elements which have a label to be displayed to the user, and a corresponding value to be returned to the server. One example is the <html:options> tag.

Note: this class has a natural ordering that is inconsistent with equals.
