[news.eclipse.technology.dali] Re: question on ResourceModelListener

[Brian Vosburgh <first.last@xxxxxxxxxx>]

For completeness's sake, yet another re-post from dali-dev:


Brian:

Just one more question: (sorry I forget my password and cannot post it to 
org.eclipse)..

I could not find JpaResourceCompilationUnit. I find JpaCompilationUnit instead.


1. Assuming that "JpaResourceCompilationUnit" is JpaCompilationUnit, I got this 
object from my jpa project and
add listener to listen different changes, but somehow all the changes I made 
from JPA details view, I didn't
get any notification, so to simplify the question, is there a way I can get 
notification whenever the change
is made from JPA details view? If I need to go with the some kind of model 
change listener, the code below is
the correct?

JavaResourcePersistentType type = 
jpaProject.getJavaPersistentTypeResource("com.test.Sess1");
if(type != null) {
JpaCompilationUnit jcu = type.getJpaCompilationUnit();
jcu.addPropertyChangeListener(new PropertyChangeListener() {
......
});
jcu.addCollectionChangeListener(new CollectionChangeListener() {
......
});
jcu.addListChangeListener(new ListChangeAdapter() {
......
});
jcu.addStateChangeListener(new StateChangeListener() {
......
});
jcu.addTreeChangeListener(new TreeChangeListener() {
......
});
jcu.getResourceModel().addResourceModelChangeListener(new ResourceModelListener() {
......
});
}

2. Also can I get the model of an annotation say @Entity in the JPACompilationUnit?
