We have isolated the code that creates the minimum BuildSettings
associated with each data mining function. The following is the code
for classification and association; code for the other mining functions
can be easily extrapolated from these. The code for classification is
shown here.

1. private BuildSettings createClassificationSettings(
2. String iTargetAttributeName) throws JDMException {

ClassificationSettingsFactory lCsFactory 3.

4. (ClassificationSettingsFactory) mDmeConn.getFactory(

5. "javax.datamining.supervised.classification"

".ClassificationSettings");

6.

ClassificationSettings lClassificationSettings 7.

8. lCsFactory.create();

if (iTargetAttributeName ! null && 9.

iTargetAttributeName.length() > 0) { 10.

11. lClassificationSettings.setTargetAttributeName(

12. iTargetAttributeName);

13. }

14. return lClassificationSettings;

15. }

The code for association is shown here.

1. private AssociationSettings createAssociationSettings(
2. int iMaxRules,

3. double iMinConfidence,

4. double iMinSupport) throws JDMException {

5. AssociationSettingsFactory lAssociationFactory

6. (AssociationSettingsFactory) mDmeConn.getFactory(

7. "javax.datamining.association.AssociationSettings");

8. AssociationSettings lAssociationSettings

9. lAssociationFactory.create();

10. lAssociationSettings.setMaxRuleLength(iMaxRules);

11. lAssociationSettings.setMinConfidence(iMinConfidence);

12. lAssociationSettings.setMinSupport(iMinSupport);

13. return lAssociationSettings;

14. }
