Class IdentifyTask

java.lang.Object
  com.esri.core.tasks.ags.identify.IdentifyTask

public class IdentifyTask
extends Object

The IdentifyTask class identifies features based on a set of parameters. The IdentifyTask class receives input parameters as an IdentifyParameters object, which specifies the details necessary for identifying features.

Use the execute() method in the class to identify features. The identified features are returned as an array of type IdentifyResult.

The IdentifyTask class extends the abstract class Task, which implements the Callable interface. The advantage of this is that you execute the IdentifyTask with another thread. The Callable interface provides the advantage that results can be returned, in this case as an array of type IdentifyResult, when the result is computed by the separate thread.
