The responder.fault method receives a parameter of the FaultEvent type and
responder.result method receives a parameter of the BATaskCompletedEvent type
whose result property contains the result of FeatureSet type.
Parameters
layerInfo:IGeographyLayerInfo — A geography layer to execute query on.

responder:IResponder — A responder to handle query results.
|
Boolean — True if the query task is started.
