Class LabelValue

java.lang.Object

com.gisgraphy.model.LabelValue

All Implemented Interfaces:

Serializable, Comparable<LabelValue>

public class LabelValue
extends Object
implements Comparable<LabelValue>, 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.
