开发 Eclipse：如何从 ICompilationUnit 获取所有继承的方法？

Question

在编写 Eclipse 插件时，如何从 ICompilationUnit 中找到所有方法，包括继承的方法？当我调用方法 getMethods() 时，没有继承方法。

@Override
public boolean test(Object receiver, String property, Object[] args, Object expectedValue) {
    IFile file = (IFile) receiver;
    try {
        IJavaElement element = JavaCore.create(file);
        ICompilationUnit icu = (ICompilationUnit) element;
        IType[] types = icu.getTypes();
        return hasMethodCalledTest(types[0]);
    } catch (Exception e) {
        System.out.println();
    }
    return false;
}

 public boolean hasMethodCalledTest(IType typeClass) {
     typeClass.getMethods();//There is no inherited method here.
     return false;
 }

我使用 ITypeHierarchy 找到了解决方案

IJavaElement element = JavaCore.create(file);
ICompilationUnit icu = (ICompilationUnit) element;
IType[] types = icu.getTypes();
ITypeHierarchy th = types[0].newTypeHierarchy(new NullProgressMonitor());
IType[] superTypes = th.getAllSuperclasses(types[0]);
