Delete entities

Use the delete (DataObject) method and DeleteControl to remove entries.

About this task

This is the hierarchical structure for the OrgContainer Sales:

• dc=yourco,dc=com
  • cn=users
    • o=Sales
      • ou=CA
        • uid=SalesPerson1
        • uid=SalesPeson2

      • ou=US
        • uid=SalesPerson3
        • uid=SalesPeson4

In this example OrgContainer Sales and its descendants are being removed from the repository.

To remove an entity, OrgContainer Sales and its descendants from the data repository, add this sample code to the application code and replace the variables with the actual values to use for this request:

DataObject root = SDOHelper.createRootDataObject();
DataObject entity = SDOHelper.createEntityDataObject(root, null, DO_ENTITY);
DataObject ctrl = SDOHelper.createControlDataObject(root, null, DO_DELETE_CONTROL);
ctrl.setBoolean(PROP_DELETE_DESCENDANTS, true);
ctrl.setBoolean(PROP_RETURN_DELETED, true);


entity.createDataObject(DO_IDENTIFIER).set(PROP_UNIQUE_NAME,
                               "o=Sales,cn=users,dc=yourco,dc=com");
 root  = service.delete(root);

Sample input and output data graphs

For this particular example the input data graph is:

<?xml version="1.0" encoding="UTF-8"?>
<sdo:datagraph xmlns:xsi="//www.w3.org/2001/XMLSchema-instance"
               xmlns:sdo="commonj.sdo"
               xmlns:wim="//www.ibm.com/websphere/wim">
<wim:Root>
<wim:entities>
<wim:identifier uniqueName="o=Sales,cn=users,dc=yourco,dc=com"/>
</wim:entities>
<wim:controls xsi:type="wim:DeleteControl" deleteDescendants="true" returnDeleted="true"/>


</wim:Root>
</sdo:datagraph> 

The resulting output data graph is:

               xmlns:sdo="commonj.sdo"
