在Eclipse中获取调用层次结构CDT

Question

我正在开发用于Eclipse CDT的插件，并且想要生成函数的调用层次结构。

有没有必要自己遍历每个文件的语法树？

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

下面是在CDT的代码，用于填充呼叫层次视图链接： http://git.eclipse.org/c/cdt/org.eclipse.cdt.git/tree/core/org.eclipse.cdt.ui/src/org/eclipse/cdt/internal/ui/callhierarchy/CHQueries.java

看起来相当复杂，其所有的内部（指其未公开API）。玩的开心。
