Class IPlugInDatasetHelper2Proxy

java.lang.Object
  com.esri.arcgis.interop.Dispatch
      com.esri.arcgis.geodatabase.IPlugInDatasetHelperProxy
          com.esri.arcgis.geodatabase.IPlugInDatasetHelper2Proxy

All Implemented Interfaces:

IPlugInDatasetHelper, IPlugInDatasetHelper2, Externalizable, Serializable

public class IPlugInDatasetHelper2Proxy
extends IPlugInDatasetHelperProxy
implements IPlugInDatasetHelper2, Serializable

Provides access to members that help Plug-In datasets.

Description

This interface allows a dataset helper to implement data source-level filtering of rows using a where clause.

Remarks

This interface can be implemented to optimize queries if there is a way to filter results from the data source more efficiently than checking the attributes of each row one-by-one. For example, data sources that have indexes should implement this interface to take advantage of indexing.

Dataset helpers for data sources without an optimized method of querying (like indexing) do not need to implement this interface.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
