Unable to find differences between two versions using ArcObjects SDK for JAVA

Vara_PrasadM_S — Thu, 12 May 2016 11:46:45 GMT

Hi All,

I am trying to fetch the differences between a child version and its parent version which is the Default Version through ArcObjects SDK for JAVA. I am not getting any results into objectIDs and differenceRows when I called "differences" function as below...

....

differenceCursor = versionedTable.differences(commonAncestorTable, esriDifferenceType.esriDifferenceTypeInsert, null);

.....

differenceCursor.next(objectIDs, differenceRows);

....

Followed the sample code given in below help document. We are using V 10.2.1

ArcObjects 10 .NET SDK Help

However, when I used "Versioning" tool bar and used "Version Changes" tool, I am able to see the changes. Could some one please help me with this.

Thanks & Regards,

Vara Prasad.

Here is my code in JAVA. I tried same approach in .NET and it worked perfect. However, in JAVA ArcObjects, I am not getting any results, always giving 'null' for both "objectID" and "differenceRow". Could someone please help me.

IVersionedWorkspace versionedWorkspace = new VersionedWorkspace(workspace);

IVersion childVersion = versionedWorkspace.findVersion("SDE.Test");

IVersion parentVersion = versionedWorkspace.getDefaultVersion();

// Cast to the IVersion2 interface to find the common ancestor.

IVersion2 childVersion2 = new IVersion2Proxy(childVersion);

commonAncestorVersion = childVersion2.getCommonAncestor(parentVersion);

// Cast the child version to IFeatureWorkspace and open the table.

IFeatureWorkspace childFWS = new IFeatureWorkspaceProxy(childVersion);

ITable childTable = childFWS.openTable(tableName);

// Cast the common ancestor version to IFeatureWorkspace and open the table.

commonAncestorFWS = new IFeatureWorkspaceProxy(commonAncestorVersion);

commonAncestorTable = commonAncestorFWS.openTable(tableName);

// Cast to the IVersionedTable interface to create a difference cursor.

IVersionedTable versionedTable = new IVersionedTableProxy(childTable);

differenceCursor = versionedTable.differences(commonAncestorTable, esriDifferenceType.esriDifferenceTypeInsert, null);

int countChildRecords = childTable.rowCount(null);

int countParentRecords = commonAncestorTable.rowCount(null);

// Create output variables for the IDifferenceCursor.Next method and a FID set.

IFIDSet fidSet = new FIDSet();

IRow[] differenceRow = null;

int[] objectID = null;

// Step through the cursor, showing the ID of each modified row.

differenceCursor.next(objectID, differenceRow);

Thanks & Regards,

Vara Prasad.

I could able to solve this. By assigning empty arrays to out parameters of "next" method instead of null object.
