public class UniqueValueDefinition
extends ClassificationDef

This class defines a unique value renderer when requesting a renderer from a dynamic map service's generateDataClasses REST endpoint.

A unique value renderer is defined by up to three fields that when taken together define a unique value for a given feature. The user can specify an optional base symbol and color ramp to be used by the renderer. A field delimiter can also be defined, this defaults to ','. This delimiter is used to separate the values when more than one field is used to define a unique value.
