Get the ancestors of an entity

Use the get(DataObject) method and the AncestorControl to show the ancestors of an entity.


About this task

This is the hierarchical structure for SalesPerson1:

In this example, the request is to show all levels of ancestors for SalesPerson1.

To request all levels of ancestors for SalesPerson1, add this sample code to the application code and replace the variables with the actual values that you want to use for this request: 

DataObject root = SDOHelper.createRootDataObject();
DataObject entity = SDOHelper.createEntityDataObject(root, null, DO_PERSON_ACCOUNT);
entity.createDataObject(DO_IDENTIFIER).setString(PROP_UNIQUE_NAME,
               "uid=SalesPerson1,ou=CA,o=Sales,cn=users,dc=yourco,dc=com");
DataObject ancesCtrl = SDOHelper.createControlDataObject(root, null, DO_ANCESTOR_CONTROL);
// 0 means all ancestors
ancesCtrl.setInt(PROP_LEVEL, 0);
ancesCtrl.getList(PROP_PROPERTIES).add("uid");
ancesCtrl.getList(PROP_PROPERTIES).add("cn");
ancesCtrl.getList(PROP_PROPERTIES).add("o");
ancesCtrl.getList(PROP_PROPERTIES).add("ou");

root = service.get(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 xsi:type="wim:PersonAccount">
<wim:identifier uniqueName="uid=SalesPerson1,ou=CA,o=Sales,cn=users,dc=yourco,dc=com"/>
</wim:entities>
<wim:controls xsi:type="wim:AncestorControl" level="0">
<wim:properties>uid
</wim:properties>
<wim:properties>cn
</wim:properties>
<wim:properties>o
</wim:properties>
<wim:properties>ou
</wim:properties>
</wim:controls>
</wim:Root>
</sdo:datagraph>

The resulting output data graph for this example is: 

<?xml version="1.0" encoding="UTF-8"?>
<sdo:datagraph xmlns:xsi="//www.w3.org/2001/XMLSchema-instance"
               xmlns:sdo="commonj.sdo"

                          repositoryId="LDAP1"
                          uniqueName="o=Sales,cn=users,dc=yourco,dc=com"/>

<wim:o>Sales
</wim:o>  
</wim:parent>  
<wim:ou>CA
</wim:ou>
</wim:parent>
</wim:entities>
</wim:Root>
</sdo:datagraph>
CA, Sales, users, and dc=yourco.dc=com are returned as the ancestors of SalesPerson1.
