com.esri.arcgis.controls
Class IEngineEnumRowProxy

java.lang.Object
  extended by com.esri.arcgis.interop.Dispatch
      extended by com.esri.arcgis.controls.IEngineEnumRowProxy
All Implemented Interfaces:
IEngineEnumRow, Externalizable, Serializable

public class IEngineEnumRowProxy
extends com.esri.arcgis.interop.Dispatch
implements IEngineEnumRow, Serializable

Provides access to members that enumerate rows in sequence.

Description

This interface is new at ArcGIS 9.3.

Use the IEngineEnumRow enumeration object when you need to maintain a collection of IRow objects in engine. 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 IEngineEnumRow object to maintain a collection of features.

The enumeration provides 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.


Product Availability

Available with ArcGIS Engine.

Throws:
IOException

getCount

public int getCount()
             throws IOException,
                    AutomationException
The number of rows.

Description

The property lists the total number of IRow objects in the enumeration.

Product Availability

Available with ArcGIS Engine.

Specified by:
getCount in interface IEngineEnumRow
Returns:
The count
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

next

public IRow next()
          throws IOException,
                 AutomationException
Retrieves the next row in the sequence.

Description

This method retreives the next IRow object in the enumeration. If the enumeration has been reset, the Next method will return the first row in the enumeration. If the enumeration is at the end of its collection, the Next method will return a NULL object.

Product Availability

Available with ArcGIS Engine.

Specified by:
next in interface IEngineEnumRow
Returns:
A reference to a com.esri.arcgis.geodatabase.IRow
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

reset

public void reset()
           throws IOException,
                  AutomationException
Resets the enumeration sequence to the beginning.

Description

This method will reset the enumeration so that the Next method will retreive the first IRow object in the collection. Use the Reset method if you need to recycle the enumeration.

Product Availability

Available with ArcGIS Engine.

Specified by:
reset in interface IEngineEnumRow
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
