public class GeoProcessor
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, IGeoProcessor

GeoProcessor Access.

Remarks

A geoprocessing tool is executed by a geoprocessor. The geoprocessor is a helper object that simplifies the task of executing tools. Toolboxes define the set of tools available for the geoprocessor. Toolboxes can be added and removed from the geoprocessor.
