makeDirty(pc, fieldName) - JDO JDOHelper's static method
Static Method javax.jdo.JDOHelper
PersistenceCapable classes are able to detect changes made to their fields. However, if a reference to an array is given to a method outside the class, and the array is modified, then the persistent instance is not aware of the change. This API allows the application to notify the instance that a change was made to a field.
Transient instances and instances of classes that do not implement
PersistenceCapable ignore this method.
fieldName- the name of the field to be marked dirty.
