Description

A protocol which must be adopted by any class wishing to be notified when query operations performed by AGSFeatureLayer complete successfully or encounter an error. An instance of the class must then be set as the queryDelegate of AGSFeatureLayer.

Defined in:

- (void) featureLayer:		(AGSFeatureLayer *)	featureLayer
operation:		(NSOperation *)	op
didQueryFeatureCountWithResult:		(NSInteger)	count
				[optional]

Tells the delegate that AGSFeatureLayer completed query for feature count successfully with the provided results.

Parameters:

	featureLayer	The feature layer which performed the query.
	op	The operation that performed the query.
	count	The number of features matching the specified query.
