Detailed Description

Labeling information about a sublayer of a map service or feature service.

LabelDefinitions can only be created from JSON currently. The JSON required follows the ArcGIS REST API specification for the various labeling objects.

An example of JSON that can be used for setting a LabelDefinition is:

   "allowOverrun":false,
   "deconflictionStrategy":"static",
   "labelExpressionInfo":{
      "expression":"$feature.state_name"
   },
