Class DictionaryRenderer

java.lang.Object
  com.esri.core.renderer.DictionaryRenderer

All Implemented Interfaces:

Renderer<Graphic>, Serializable

public class DictionaryRenderer
extends Object
implements Renderer<Graphic>

This is a renderer defined by dictionary. It exposes methods to control the visibility of text items within symbols.The visibility can be set through a message type file which is stored in the resource bundle for MessageProcessor. The visibility defined in the message type file can be overridden by the setter methods exposed in DictionaryRenderer. However, the overridden visibility settings has no effect on the symbols added earlier. A message type file defined in a Json file:

{
 "type": "position_report",
 "layerName": "position_reports",
 "renderer":
 {
   "type" : "dictionary",
   "description"    : "",
   "dictionaryType" : "2525C",
   "field" : "sic",
   "symbolScaleFactor" : 1.0,
   "labelsVisible" : true,
   "minLabelScale" : 1000000,
   "maxLabelScale" : 100000
 }
}
