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:

<field name="lines">
