Class IEnumRowProxy

java.lang.Object
  com.esri.arcgis.interop.Dispatch
      com.esri.arcgis.editor.IEnumRowProxy

All Implemented Interfaces:

IEnumRow, Externalizable, Serializable

Direct Known Subclasses:

IEnumRow2Proxy

public class IEnumRowProxy
extends com.esri.arcgis.interop.Dispatch
implements IEnumRow, Serializable

Provides access to members that enumerate rows in sequence.

Remarks

The IEnumRow object is an enumeration and methods to cycle through it.

Use the Count method to identify how many objects exist within the collection.

Use the Next method to retrieve the next object in the enumeration.

Use the Reset method to reset the enumeration to the first object in the collection.

Click on the example to see the associate example of how the IEnumRow interface can be used when building a custom feature inspector. Also note that this example does not fully explain what a custom feature inspector is. Refer to the documentation of IObjectInspector for details.

When To Use

Use the IEnumRow object when you need to maintain a collection of IRow objects.

The collection itself can consist of any object that implements the IRow interface. For example, the Feature coclass implements the IRow interface so you can use the IEnumRow object to maintain a collection of features.
