I am struggling to create an aspectj pointcut because I can't figure out how to limit a pointcut to calls from an object's constructor to its own methods (but exclude calls to methods on other instances of the same class). Background: I have an application with objects that need to notify their "watchers" whenever the object's data changes. To implement this I have methods decorated with a @NotifiableChange annotation, and an aspect that triggers the notification process after these method calls complete. The difficulty is that I do NOT want to trigger notifications during object construction, only when methods are called AFTER construction. I.e. calls from objectA's constructor to objectA's own methods should not be included in the pointcut. However, calls to objectB's methods made during the course of objectA's constructor should be included in the pointcut. I've completely tied myself in knots trying all varieties of withincode, within, cflow, this and target but just can't create the right pointcut. This is what I have now: (DataChangeNotifier is the interface implemented by the relevant classes) <pre><code>pointcut callsWithinConstructors(DataChangeNotifier notifierObject): // call to a notifiable method call(@NotifiableChange * *(..)) //on this object && this(notifierObject) //in the execution of a constructor && withincode(DataChangeNotifier+.new(..)); // cut any method with any parameters with this annotation pointcut notifiable(DataChangeNotifier notifierObject): call(@NotifiableChange * DataChangeNotifier+.*(..)) && target(notifierObject) //but not from the constructors (because there should be no notifications during construction) && !cflow(callsWithinConstructors(DataChangeNotifier+)) //and not from the method that gets called by notifiers - this method is handled below && !withincode(* DataChangeNotifier+.listenedDataHasChanged(..)); </code></pre> but it seems the first pointcut is excluding ALL method calls that take place within the constructor, not just those to its own methods. Please help - I'm going crazy! Thanks

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
