is it ok to clear vector in a destructor

class M {
};

class E {
   public:
     ~E();     
   private:
    MyVector mv;

}; 

E::~E() {
   mv.clear()
}

typedef MyHashMap<M*, E*> EMap;
typedef MyHashMap<M*, E*>::iterator EMapItr;

class A : public class Base {

    public:
        ~A();
        const EMap& getEMap() { return p_emap};  
        virtual void  func();

    protected:
        EMap p_Map;
};

A::~A() {
   EMapItr eMItr = p_Map.beginRandom();
   for(; eMItr; ++eMItr) {
      delete eMItr.value();
   }
}
class DB {
    public fill(EMap* p_Map);
};

class Derived: public A {
    private:
       DB dp;   
};

class GUI {
    public:
      void guiFunc();  
}

void GUI:guiFunc() {
   Derived* d = new Derived;
   d->func(); 

}

void Derived::func() {
   db.fill(&p_map);
}

Please note MyHashMap is my customised hashmap . the functionality is same as std:hashmap Please note MyVector is customise form of std::vector . the functionality is same as std:vector

I do not want to delete Pointer of M class M*

is the following code correct or do yo see any problem in the same

A::~A() {
   EMapItr eMItr = p_Map.beginRandom();
   for(; eMItr; ++eMItr) {
      delete eMItr.value();
   }
}

Also do we need to clear the vector as below or it will be automatically taken care E::~E() { mv.clear() }
