Example 1 with ValueInjector

use of org.apache.cayenne.exp.ValueInjector in project cayenne by apache.

the class BaseContext method injectInitialValue.

 * If ObjEntity qualifier is set, asks it to inject initial value to an
 * object. Also performs all Persistent initialization operations
 */

    // i.e. have
    // the id and the context in place BEFORE setPersistence is called
