How to use Intersect tool in ArcObjects

Question

I'm trying to use the Intersect tool in ArcObjects SDK Java with two feature classes.

Here is my code:

 public void intersectTwoFeatureClasses(Object in1, Object in2, Object out) throws UnknownHostException, IOException {
 IGpValueTableObject intersectInFeatures = new GpValueTableObject();
 intersectInFeatures.setColumns(2);
 intersectInFeatures.setValue(0, 0, in1);
 intersectInFeatures.setValue(0, 1, 1);
 intersectInFeatures.setValue(1, 0, in2);
 intersectInFeatures.setValue(1, 1, 1);
 Intersect intersect = new Intersect(intersectInFeatures, out);
 IGeoProcessorResult result = gp.execute(intersect, null);
 if(result.getStatus() != esriJobStatus.esriJobSucceeded)
 return;
}

But I get an Automation Exception: Item Not Found in this Collection. in 'DAO.Fields'.

The way I create my IGPValueTableObject seems to be wrong.

Does anyone know how to create it for two feature classes ?

• Hornbydd: Have a look at this page, it shows an alternate method for populating the ValueTable.

Answer 1

Here is a working and simpler solution I found:

Intersect intersect = new Intersect(in1 + ";" + in2, out);

where in1 , in2 and out are strings giving the full path of input and output is a IFeatureClass
