r7363 r7373 37 37 @file 38 38 @ingroup Object SmartPtr 39 @brief Definition of SmartPtr<T>. 40 41 @anchor SmartPtrExample 42 43 orxonox::SmartPtr is an implementation of a smart pointer - it wraps a pointer to an 44 object and keeps this object alive until no SmartPtr points to this object anymore. 45 In contrast to orxonox::SharedPtr, SmartPtr works only with classes that are derived 46 from orxonox::OrxonoxClass, because it's an intrusive implementation, meaning the 47 reference counter is stored in the object itself. 48 49 It's possible to use normal pointers and smart pointers to an object simultaneously. 50 You don't have to use SmartPtr all the time, you can create a SmartPtr for an object 51 at any time and also convert it back to a normal pointer if you like. This is possible 52 because the reference counter is stored in the object itself and not in SmartPtr (in 53 contrast to SharedPtr). 54 55 @b Important: If you want to delete an object, you must not use @c delete @c object but 56 rather @c object->destroy(). This function will check if there are smart pointers 57 pointing to the object. If yes, the object will be kept alive until all smart pointes 58 are destroyed. If no, the object is deleted instantly. 59 60 If all smart pointers that point to an object are destroyed, but you never called 61 @c object->destroy() before, the object will not be deleted! All a SmartPtr will do 62 is to really just keep an object alive, but it will not delete it automatically 63 unless you tried to destroy it before. 64 65 Example: 66 @code 67 class MyClass // class declaration 68 { 69 public: 70 void setObject(OtherClass* object) // passes a normal pointer which will be stored in a SmartPtr 71 { this->object_ = object; } 72 73 OtherClass* getObject() const // converts the SmartPtr to a normal pointer and returns it 74 { return this->object_; } 75 76 private: 77 SmartPtr<OtherClass> object_; // a pointer to an instance of OtherClass is stored in a SmartPtr 78 }; 79 @endcode 80 In this example we assume that OtherClass is a child of OrxonoxClass. We don't care 81 about the inheritance of MyClass though. 82 83 Now we create an instance of MyClass and assign a pointer to an instance of OtherClass: 84 @code 85 MyClass* myclass = new MyClass(); // create an instance of MyClass 86 OtherClass* object = new OtherClass(); // create an instance of OtherClass 87 myclass->setObject(object); // the object is now stored in a SmartPtr inside myclass 88 89 object->destroy(); // we try to destroy object, but there's still a SmartPtr pointing at it. 90 91 # object still exists at this point (because a SmartPtr points at it) 92 93 delete myclass; // now we delete myclass, which also destroys the SmartPtr 94 95 # object doesn't exist anymore (because the SmartPtr is now destroyed) 96 @endcode 97 98 Now we look at the same example, but we first delete myclass, then destroy object: 99 @code 100 MyClass* myclass = new MyClass(); // create an instance of MyClass 101 OtherClass* object = new OtherClass(); // create an instance of OtherClass 102 myclass->setObject(object); // the object is now stored in a SmartPtr inside myclass 103 104 delete myclass; // we delete myclass, which also destroys the SmartPtr 105 106 # object still exists at this point (because destroy() was not called yet) 107 108 object->destroy(); // now we try to destroy object, which works instantly 109 110 # object doesn't exist anymore (because we just destroyed it) 111 @endcode 112 113 Note that in any case @c object->destroy() has to be called to delete the object. 114 However if a SmartPtr points at it, the destruction is delayed until all SmartPtr 115 are destroyed. 39 116 */ 40 117 … … 52 129 namespace orxonox 53 130 { 131 /** 132 @brief A smart pointer which wraps a pointer to an object and keeps this object alive as long as the smart pointer exists. 133 134 @see See @ref SmartPtrExample "this description" for more information and an example. 135 */ 54 136 template <class T> 55 137 class SmartPtr 56 138 { 57 139 public: 140 /// Constructor: Initializes the smart pointer with a null pointer. 58 141 inline SmartPtr() : pointer_(0), base_(0) 59 142 { 60 143 } 61 144 145 /// Constructor: Used to explicitly initialize the smart pointer with a null pointer 62 146 inline SmartPtr(int) : pointer_(0), base_(0) 63 147 { 64 148 } 65 149 150 /// Constructor: Initializes the smart pointer with a pointer to an object. @param pointer The pointer @param bAddRef If true, the reference counter is increased.

r7363 r7373 32 32 @file 33 33 @ingroup Object SmartPtr 34 @brief Definition of WeakPtr<T>. 35 36 @anchor WeakPtrExample 37 38 A WeakPtr wraps a pointer to an object. If the object gets deleted, the WeakPtr becomes 39 NULL. This can be used to store pointers to objects without knowing when they will be 40 destroyed. 41 42 WeakPtr works only with objects that are derived from orxonox::OrxonoxClass, because 43 WeakPtr is intrusive and registers itself in the stored object, to get a notification if 44 the object is being deleted. 45 46 Example: 47 @code 48 MyClass* object = new MyClass(); // create an instance of MyClass 49 50 WeakPtr<MyClass> pointer = object; // create a WeakPtr and assign the object 51 52 if (pointer) // checks if pointer is not NULL (which is true) 53 pointer->someFunction(); // calls MyClass::someFunction() 54 55 object->destroy(); // calls destroy() which deletes the object 56 57 if (pointer) // checks if pointer is not NULL (which is now false) 58 pointer->someFunction(); // this will not be executed 59 @endcode 60 In this example we assumed that MyClass is derived of OrxonoxClass (otherwise it couldn't 61 be used with a WeakPtr). 62 63 A callback can be registerd with the WeakPtr that will be called if the object gets deleted. 64 @code 65 void myCallback() // definition of the callback function 66 { 67 COUT(0) << "Object destroyed" << std::endl; 68 } 69 70 MyClass* object = new MyClass(); // create an instance of MyClass 71 72 WeakPtr<MyClass> pointer = object; // create a WeakPtr and assign the object 73 74 pointer.setCallback(createFunctor(&myCallback)); // defines a callback 75 76 object->destroy(); // calls destroy() which deletes the object. prints "Object destroyed" to the console 77 @endcode 34 78 */ 35 79 … … 46 90 namespace orxonox 47 91 { 92 /** 93 @brief WeakPtr wraps a pointer to an object, which becomes NULL if the object is deleted. 94 95 @see See @ref WeakPtrExample "this description" for more information and an example. 96 */ 48 97 template <class T> 49 98 class WeakPtr … … 52 101 53 102 public: 103 /// Constructor: Initializes the weak pointer with a null pointer. 54 104 inline WeakPtr() : pointer_(0), base_(0), callback_(0) 55 105 { 56 106 } 57 107 108 /// Constructor: Used to explicitly initialize the weak pointer with a null pointer 58 109 inline WeakPtr(int) : pointer_(0), base_(0), callback_(0) 59 110 { 60 111 } 61 112 113 /// Constructor: Initializes the weak pointer with a pointer to an object. 62 114 inline WeakPtr(T* pointer) : pointer_(pointer), base_(pointer), callback_(0) 63 115 { … … 66 118 } 67 119 120 /// Copy-constructor 68 121 inline WeakPtr(const WeakPtr& other) : pointer_(other.pointer_), base_(other.base_), callback_(0) 69 122 { … … 72 125 } 73 126 127 /// Copy-constructor for weak pointers to objects of another class. 74 128 template <class O> 75 129 inline WeakPtr(const WeakPtr<O>& other) : pointer_(other.get()), base_(other.base_), callback_(0) … … 79 133 } 80 134 135 /// Destructor 81 136 inline ~WeakPtr() 82 137 { … … 86 141 } 87 142 143 /// Used to assign a null pointer. 88 144 inline WeakPtr& operator=(int) 89 145 { … … 92 148 } 93 149 150 /// Assigns a new pointer. 94 151 inline WeakPtr& operator=(T* pointer) 95 152 { … … 98 155 } 99 156 157 /// Assigns the wrapped pointer of another WeakPtr. 100 158 inline WeakPtr& operator=(const WeakPtr& other) 101 159 { … … 104 162 } 105 163 164 /// Assigns the wrapped pointer of a WeakPtr of another class 106 165 template <class O> 107 166 inline WeakPtr& operator=(const WeakPtr<O>& other) … … 111 170 } 112 171 172 /// Returns the wrapped pointer as @c T* 113 173 inline T* get() const 114 174 { … … 116 176 } 117 177 178 /// Returns the wrapped pointer as @c OrxonoxClass* 118 179 inline OrxonoxClass* getBase() const 119 180 { … … 121 182 } 122 183 184 /// Implicitly converts the WeakPtr to a pointer of type @c T* 123 185 inline operator T*() const 124 186 { … … 126 188 } 127 189 190 /// Overloaded operator, returns a pointer to the stored object. 128 191 inline T* operator->() const 129 192 { … … 132 195 } 133 196 197 /// Overloaded operator, returns a reference to the stored object. 134 198 inline T& operator*() const 135 199 { … … 138 202 } 139 203 204 /// Returns true if the wrapped pointer is NULL. 140 205 inline bool operator!() const 141 206 { … … 143 208 } 144 209 210 /// Swaps the contents of two weak pointers. 145 211 inline void swap(WeakPtr& other) 146 212 { … … 167 233 } 168 234 235 /// Resets the weak pointer (equivalent to assigning a NULL pointer). 169 236 inline void reset() 170 237 { … … 172 239 } 173 240 241 /// Registers a callback that will be executed if the stored object is destroyed. 174 242 inline void setCallback(const FunctorPtr& callback) 175 243 { … … 177 245 } 178 246 247 /// Returns the registered callback. 179 248 inline const FunctorPtr& getCallback() const 180 249 { … … 183 252 184 253 private: 254 /// Will be called by OrxonoxClass::~OrxonoxClass() if the stored object is deleted.
