- (void) queryTask:		(AGSQueryTask *)	queryTask
operation:		(NSOperation *)	op
didExecuteWithFeatureCount:		(NSInteger)	count
				[optional]

Tells the delegate that AGSQueryTask completed query with feature count successfully.

Parameters:

	queryTask	The task which performed the query.
	op	NSOperation that performed the query task.
	count	The feature count returned by the query.

1.0

- (void) queryTask:		(AGSQueryTask *)	queryTask
operation:		(NSOperation *)	op
didExecuteWithFeatureSetResult:		(AGSFeatureSet *)	featureSet
				[optional]

Tells the delegate that AGSQueryTask completed successfully with the provided results.

Parameters:

	queryTask	The task which performed the query.
	op	NSOperation that performed the query task.
	featureSet	The feature set returned by executing query.

1.0

- (void) queryTask:		(AGSQueryTask *)	queryTask
operation:		(NSOperation *)	op
didExecuteWithObjectIds:		(NSArray *)	objectIds
				[optional]

Tells the delegate that AGSQueryTask completed query for IDs successfully with the provided results.

Parameters:

	queryTask	The task which performed the query.
	op	NSOperation that performed the query task.
	objectIds	The array of object IDs returned by executing query.

- (void) queryTask:		(AGSQueryTask *)	queryTask
operation:		(NSOperation *)	op
didFailQueryFeatureCountWithError:		(NSError *)	error
				[optional]

Tells the delegate that AGSQueryTask encountered an error while performing query for feature count.

Parameters:

	queryTask	The task which performed the query.
	op	NSOperation that performed the query task.
	error	Information about the error returned by the service.
