Hello
My problem concerns the results of the SearchEngine used in a plugin
implementing CompletionAssist in javaEditor. My goal is obtain all fields
in a method. The following code permits to get all member class fields but
not the fields declared in the method. Is-it possible to do? What's failed
in my code ?
------------------------------------------------------------ ----------------
IWorkbenchPage page=PlatformUI.getWorkbench().getActiveWorkbenchWindow()
.getActivePage();
IJavaElement element= JavaUI.getEditorInputJavaElement(
page.getActiveEditor().getEditorInput());
IJavaSearchScope scope = SearchEngine.createJavaSearchScope(
new IJavaElement[] { element } ,true);
IEditorPart editor = page.getActiveEditor();
IFile file = ((IFileEditorInput) editor.getEditorInput()).getFile();
IJavaProject project = JavaCore.create(file.getProject());
SearchPattern searchPattern = SearchPattern.createPattern(
"*",
IJavaSearchConstants.FIELD,
IJavaSearchConstants.DECLARATIONS,
SearchPattern.R_PATTERN_MATCH);
final List<Object> list = new ArrayList<Object>();
SearchRequestor requestor = new SearchRequestor() {
public void acceptSearchMatch(SearchMatch match) {
Object element = match.getElement();
list.add((Object)element);
if (element instanceof IJavaElement) {
logger.debug("element is IJavaElement");
IJavaElement e = (IJavaElement)element;
logger.debug(e.getAdapter(IJavaElement.class));
logger.debug(e.getClass());
}
}
};
SearchEngine searchEngine = new SearchEngine();
try {
searchEngine.search(searchPattern,
new SearchParticipant[] {
SearchEngine.getDefaultSearchParticipant()},
scope,
requestor,
new NullProgressMonitor());
} catch (CoreException e) {
logger.debug(e.getMessage());
}
------------------------------------------------------------ ---------------
So, editing the following sample class :
------------------------------------------------------------ ---------------
public class cc {
private Object1 obj1= null;
private Object2 obj2= null;
/**
* Main
*/
public static void main(String[] args) {
new cc();
}
/**
* Constructor
*/
public cc() {
try {
....
Object3 obj3 = new Object3();
// Fills input datas
obj3.get <---------------- completion
}
}
}
------------------------------------------------------------ --------------
... when I ask completion, my code is executed but only obj1 and obj2 are
found... not obj3 in constructor...
Thanks for your help

Fields cannot be declared inside a method.
