Changed Listener - how to distinguish changes in ElementChangedEvent [message #158367]

Hi!

When deleting a class in the Package Explorer it returns the same
ElementChangedEvent as when I change i.e. a line of code within a class.

So how can I distinguish those events?

And when is POST_RECONCILE or POST_CHANGE triggered?

And the other problem is how to know whether only a method within a class,
the class itself or even only an attribute has been changed.
At the moment I only get event for the whole class (compilation unit)
instead of the single members of that class.

Thanks in advance

You need to look at the Java delta associated with the EclementChangedEvent.
If you visit this delta, it will indicate in the fisrt case that the class
has been removed, and in the second case that the content of the compilation
unit has changed.

> And when is POST_RECONCILE or POST_CHANGE triggered?
POST_RECONCILE is triggered after you edited some compilation unit in the
Java editor.
POST_CHANGE is triggered after a Java resource is changed on disk.

Have a look at the Java delta.

If there are no structural change to a member, then the Java delta will only
indicate that the content of the compilation unit has changed.

hi

i'm also interested in knowing when a method in a class has changed or a
new one has been added.

What do i have to look to do this? are there any existing listener for
these cases?

thank you
