openCMIS: Remove secondary type from the object

In my previous post, I showed you how to add secondary type to a cmis object. CMIS provides a way to remove the secondary properties assigned to an object.

From the above image, you can observe that the document ‘emptyDocument.txt’ has two secondary types associated with it.

a.   abc:secondaryType

b.   abc:confidentialDocs

Below statements are used to remove the secondary type ‘abc:confidentialDocs’.

                  /* Get current secondary types */

                  List<String> secondaryTypes = cmisObject.getPropertyValue(PropertyIds.SECONDARY_OBJECT_TYPE_IDS);

                  if (secondaryTypes == null) {

                           System.out.println("No secondary types associated to this object");

                           return;

                  }

                  Map<String, Object> properties = new HashMap<String, Object>();

                  /* Remove the new secondary type */

                  secondaryTypes.remove("abc:confidentialDocs");

                  properties.put(PropertyIds.SECONDARY_OBJECT_TYPE_IDS, secondaryTypes);

                  /* update properties */

                  cmisObject.updateProperties(properties);

Find the below working application.

  return sessionFactory.createSession(parameters);
 }

 private static void printDocument(CmisObject cmisObject) {
  System.out.println("***********************************************");
  System.out.println("contact us : " + cmisObject.getPropertyValue("abc:contactUs"));

  System.out.println("confidentialValue : " + cmisObject.getPropertyValue("abc:confidentialLevel"));

  List<String> secondaryTypes = cmisObject.getPropertyValue(PropertyIds.SECONDARY_OBJECT_TYPE_IDS);

  System.out.println("Secondary types are");
  for (String secondaryType : secondaryTypes) {
   System.out.println(secondaryType);
  }
 }

 public static void main(String args[]) throws IOException {

  Session session = getSession();

  CmisObject cmisObject = session.getObjectByPath("/emptyDocument.txt");

  System.out.println("Before removing secondary type 'abc:confidentialDocs'");
  printDocument(cmisObject);
  
  /* Get current secondary types */
  List<String> secondaryTypes = cmisObject.getPropertyValue(PropertyIds.SECONDARY_OBJECT_TYPE_IDS);
  if (secondaryTypes == null) {
   System.out.println("No secondary types associated to this object");

  Map<String, Object> properties = new HashMap<String, Object>();

  /* Remove the new secondary type */
  secondaryTypes.remove("abc:confidentialDocs");
  properties.put(PropertyIds.SECONDARY_OBJECT_TYPE_IDS, secondaryTypes);

  /* update properties */
  cmisObject.updateProperties(properties);

  System.out.println("\nAfter removing secondary type 'abc:confidentialDocs'");
  printDocument((Document) cmisObject);
 }

}

Output

Before removing secondary type 'abc:confidentialDocs'

As you see the output, the secondary type ‘abc:confidentialDocs’ is removed for the cmis object. You can observe the same in below workbench image.
