Constructor Detail

DifferenceCursor

public DifferenceCursor(Object obj)
                 throws IOException

Construct a DifferenceCursor using a reference to such an object returned from ArcGIS Engine or Server. This is semantically equivalent to casting obj to DifferenceCursor.
Casting to this class from the return value of a method will not work, as this class represents an abstract class in ArcObjects.
*
DifferenceCursor o = (DifferenceCursor)obj; // will not work

DifferenceCursor o = new DifferenceCursor(obj); // Use this constructor instead
* @param obj an object returned from ArcGIS Engine or Server

Throws:

IOException - if there are interop problems DifferenceCursor theDifferenceCursor = (DifferenceCursor) obj;

Method Detail

equals

public boolean equals(Object o)

Compare this object with another

Overrides:

equals in class Object

hashCode

public int hashCode()

the hashcode for this object

Overrides:

hashCode in class Object

next

public void next(int[] oID,
                 IRow[] differenceRow)
          throws IOException,
                 AutomationException

Returns the object identifier or difference row.

Remarks

The Next method returns an object ID of an IRow.

IRow objects returned from a difference cursor are meant to be a read only. If row editing is desired the OID returned from the call to IDifferenceCursor::NextRow should be used in a call ITable::GetRow or ITable::GetRows methods.

Product Availability

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