该示例基于 org.eclipse.jdt.internal.* 类,我认为您不需要花费太多精力来执行此操作,因为 JDT SearchEngine API 功能齐全。在您的情况下,以下代码就足够了:
IWorkspace workspace = ResourcesPlugin.getWorkspace();
IWorkspaceRoot root = workspace.getRoot();
IProject plainProject = root.getProject("some project");
IJavaProject javaProject = JavaCore.create(plainProject);
try {
IType type = javaProject.findType("foo.bar.AnotherClass");
IField field = type.getField("z");
//IJavaSearchScope scope = SearchEngine.createWorkspaceScope();
IJavaSearchScope scope = SearchEngine.createJavaSearchScope(new IJavaElement[] { plainProject });
SearchPattern searchParttern = SearchPattern.createPattern(field,
IJavaSearchConstants.REFERENCES);
SearchRequestor requestor = new SearchRequestor() {
@Override
public void acceptSearchMatch(SearchMatch match) {
System.out.println(match.getElement());
}
};
SearchEngine searchEngine = new SearchEngine();
searchEngine.search(searchParttern,
new SearchParticipant[] { SearchEngine.getDefaultSearchParticipant() }, scope,
requestor, new NullProgressMonitor());
} catch (Exception e) {
// some exception handling you need to do
}
