在Eclipse CDT中獲取調用層次結構

Question

我正在為Eclipse CDT開發一個插件，我想生成一個函數的調用層次結構。

是否可以自己遍歷每個文件的語法樹？

Answer 1

CallHierarchy hierarchy = new CallHierarchy();
IJavaSearchScope searchScope = SearchEngine.createWorkspaceScope();
hierarchy.setSearchScope(searchScope);
ArrayList<MethodCall> methodCalls = new ArrayList<MethodCall>();

MethodWrapper[] callerWrapper = hierarchy.getCallerRoots(methods);
ArrayList<MethodWrapper> callsWrapper = new ArrayList<MethodWrapper>();
for (int i = 0; i < callerWrapper.length; i++) {
    callsWrapper.addAll(Arrays.asList(callerWrapper[i]
            .getCalls(new NullProgressMonitor())));
}

for (int i = 0; i < callsWrapper.size(); i++)
    methodCalls.add(callsWrapper.get(i).getMethodCall());
// Now you will get method calls in methodCalls list.
IMember member = methodCalls.get(0).getMember();// you will get one of
                                                // caller method in
                                                // member by this method

這是CDT中用於填充調用層次結構視圖的代碼的鏈接： http ： //git.eclipse.org/c/cdt/org.eclipse.cdt.git/tree/core/org.eclipse.cdt。 UI / SRC /組織/蝕/ CDT /內部/ UI / callhierarchy / CHQueries.java

看起來很復雜，它的內部（意味着它不是公共API）。 玩得開心。
