Hi All,

I have tried to find out some implementation details from the JDT core in
order to see best practice examples. Some Java Elements implement the
IParent interface which defines the method getChildren() and
hasChildren(). However I cant find the implementation of these methods
anywhere.

For example IJavaModel is implemented by JavaModel and extends IParent. I
cant find the IParent methods implemented neither in JavaModel nor in its
superclasses.

Any ideas? Or any ideas who I could ask?

Philipp

look at
org.eclipse.jdt.internal.core.BinaryType.getChildren()
org.eclipse.jdt.internal.core.ClassFileWorkingCopy.getChildr en()
org.eclipse.jdt.internal.core.JavaElement.getChildren()

Open a type hierarchy on IParent. Press the leftmost button in the lower
pane's toolbar. Voila.

Thomas,
that does not do all the work.

JavaElement does not implement IParent but it does include a method
getChildren().

That's where Philipp's confussion came from - the hierarchy view does
not show you the one method you care about: JavaElemement.getChildren()
which made it fairly useless in this case.

I'd say it's a missing functionality but it has not bothered me
personally yet.

cheers.

Yes, I see. That's quite confusing, actually. I've seen the pattern (not
in THAT sense) before, but I never liked it (I guess I'm easily confused
;-).
