Hi JDT gurus,
I'd like to find all constructors that are available in 'java.lang'.
Therefore I do the following:
IJavaSearchScope searchScope = SearchEngine.createJavaSearchScope(new
IJavaElement[] { javaProject });
SearchRequestor searchRequestor = new SearchRequestor() {
@Override
public void acceptSearchMatch(SearchMatch match) throws CoreException {
Object element = match.getElement();
if (element instanceof IMethod) {
System.out.println(((IMethod) element).getElementName());
} else if (element instanceof IType) {
System.err.print("IType ??? ");
System.err.println(((IType) element).getElementName());
}
}
};
doSearch(searchScope, searchRequestor);
with
public void doSearch(IJavaSearchScope searchScope, SearchRequestor
searchRequestor) throws CoreException {
SearchPattern pattern = new
ConstructorDeclarationPattern("java.lang".toCharArray(), null,
SearchPattern.R_PREFIX_MATCH);
new SearchEngine().search(pattern,
SearchUtils.getDefaultSearchParticipants(), searchScope,
searchRequestor, new NullProgressMonitor());
}
I can see e.g. these entries in the dump (among others which follow a
similar pattern). Where do they come from and what am I doing wrong to
get constructor declarations instead of ITypes?
// CNFE has 3 constructors but is listed 5 times
IType ??? ClassNotFoundException
IType ??? ClassNotFoundException
IType ??? ClassNotFoundException
IType ??? ClassNotFoundException
IType ??? ClassNotFoundException
// huh? results from an interface
IType ??? CharSequence
IType ??? CharSequence
Regards,
Sebastian
