Sets a reference to a persistent class or the persistent values in a collection, array or map to be considered dependent. Dependent objects are deleted when the instance referring to them is deleted.
OpenAccess ORM does not check for other references to the instances deleted so this extension should only be used for objects that are not referenced from anywhere else.
The XML metadata for the same is given below:
<extension key="dependent" value="true" />
<collection element-type="OrderLine" />
