     35    @file
     36    @ingroup Util SharedPtr
     37    @brief Definition of the SharedPtr template that is used to manage pointers.
     38
     39    @anchor SharedPtrExample
     40
     41    The orxonox::SharedPtr template can be used to manage a pointer to an object
     42    that was created with new. The SharedPtr acts like the pointer itself, but it
     43    keeps track of the number of references to it. If all references are removed,
     44    SharedPtr deletes the managed object automatically.
     45
     46    Example:
     47
     48    Classic implementation using new and delete:
     49    @code
     50    void someFunction()
     51    {
     52        MyClass* object = new MyClass();            // Create a new instance of MyClass
     53
     54        object->myFunction();                       // Calls MyClass::myFunction()
     55
     56        delete object;                              // Delete the object at the end of the scope
     57    }
     58    @endcode
     59
     60    The same function using SharedPtr:
     61    @code
     62    void someFunction()
     63    {
     64        SharedPtr<MyClass> object = new MyClass();  // Create a new instance of MyClass and store its pointer in a SharedPtr
     65
     66        object->myFunction();                       // Calls MyClass::myFunction()
     67
     68    }                                               // At the end of the scope, the SharedPtr is destroyed. Because no other SharedPtrs
     69                                                    // point at the object, the object itself is also destroyed automatically
     70    @endcode
     71
     72    This is especially handy if you do not know what will happen with an object that was
     73    created with new, for example if you pass it to another object. If multiple instances
     74    share a pointer to the same object, none of these instances can delete the object
     75    without interfering with the other instances. But if none of the instances destroy the
     76    object, it will never be destroyed and results in a memory leak. With a SharedPtr
     77    however you don't have to think about destroying the object, because the SharedPtr
     78    itself keeps track of the references.
     79
     80    Example:
     81
     82    Classic implementation using new and delete:
     83    @code
     84    class OtherClass                                    // Declaration of some class
     85    {
     86        public:
     87            OtherClass(MyClass* object)                 // Constructor
     88            {
     89                this->object_ = object;                 // Assigns the pointer to the member variable object_
     90            }
     91
     92            ~OtherClass()                               // Destructor
     93            {
     94                ???                                     // What to do with object_?
     95            }
     96
     97        private:
     98            MyClass* object_;                           // A pointer to the object
     99    };
     100
     101    void someFunction()
     102    {
     103        MyClass* object = new MyClass();                // Create a new instance of MyClass
     104
     105        OtherClass* other1 = new OtherClass(object);    // Create an instance of OtherClass and pass the object pointer
     106        OtherClass* other2 = new OtherClass(object);    // "
     107        OtherClass* other3 = new OtherClass(object);    // "
     108
     109        ???                                             // What happens with object now?
     110    }
     111    @endcode
     112
     113    If you use SharedPtr<MyClass> instead of a classic MyClass* pointer, the instance of
     114    MyClass would be automatically destroyed if all instances of OtherClass are destroyed.
     115    You don't need any code in the destructor and you can completely forget about the
     116    object, because its managed by the SharedPtr.
     117
     118    The same code using SharedPtr:
     119    @code
     120    class OtherClass                                        // Declaration of some class
     121    {
     122        public:
     123            OtherClass(const SharedPtr<MyClass>& object)    // Constructor
     124            {
     125                this->object_ = object;                     // Assigns the pointer to the member variable object_
     126            }
     127
     128        private:
     129            SharedPtr<MyClass> object_;                     // A SharedPtr to the object
     130    };
     131
     132    void someFunction()
     133    {
     134        SharedPtr<MyClass> object = new MyClass();          // Create a new instance of MyClass
     135
     136        OtherClass* other1 = new OtherClass(object);        // Create an instance of OtherClass and pass the object pointer
     137        OtherClass* other2 = new OtherClass(object);        // "
     138        OtherClass* other3 = new OtherClass(object);        // "
     139
     140    }                                                       // The SmartPtr "object" is destroyed at the end of the scope,
     141                                                            // but the three instances of OtherClass keep the object alive
     142                                                            // until they are all destroyed.

     331        @param T The type of the managed object
     332        @param Parent The type of the SharedPtr that manages the parent class of @a T
     333
     334        This class is used to reflect the hierarchy of the underlying class @a T.
     335        For example the @c Functor classes: While a @c Functor* pointer would be managed by
     336        @c SharedPtr<Functor>, the child class @c FunctorStatic is managed by the class
     337        <tt>SharedChildPtr<FunctorStatic, SharedPtr<Functor> ></tt>.
     338
     339        The second template argument @a Parent is used as the parent class of
     340        SharedChildPtr. This means that each instance of <tt>SharedChildPtr<T, Parent></tt>
     341        can be upcasted to @c Parent.
     342
     343        So for example this works:
     344        @code
     345        SharedChildPtr<FunctorStatic, SharedPtr<Functor> > functorStatic = createFunctor(&MyClass::myStaticFunction);
     346        SharedPtr<Functor> functor = functorStatic;
     347        @endcode
     348
     349        @note There are some typedefs and more to make the usage of SharedChildPtr easier
     350        for the classes Functor and Executor. See FunctorPtr.h and ExecutorPtr.h. The above
     351        example could thus be simplified the following way:
     352        @code
     353        FunctorStaticPtr functorStatic = createFunctor(&MyClass::myStaticFunction);
     354        FunctorPtr functor = functorStatic;
     355        @endcode
     356
     357        @see See SharedPtr for more information about the base class SharedPtr.
     358        @see See @ref SharedPtrExample "this description" for some examples about how to use SharedPtr.

     37    @brief Declaration of SmallObjectAllocator

     39    @anchor SmallObjectAllocatorExample
     40
     41    The default implementations of new and delete are designed to work with objects of
     42    arbitrary size. They are thus not optimal for small objects.
     43    @ref orxonox::SmallObjectAllocator "SmallObjectAllocator" allocates a large memory
     44    block and divides it into small chunks. These chunks are returned by the function
     45    @ref orxonox::SmallObjectAllocator::alloc() "alloc()" and can be used to create a
     46    new object using the placement new operator. Instead of delete, the function
     47    @ref orxonox::SmallObjectAllocator::free() "free()" is used to give the memory
     48    back to SmallObjectAllocator.
     49
     50    Example:
     51    @code
     52    SmallObjectAllocator allocator(sizeof(MySmallObject));  // Create an allocator. The size of the memory chunks must equal the size of the desired class
     53
     54    void* chunk = allocator.alloc();                        // Allocate a memory chunk
     55    MySmallObject* object = new (chunk) MySmallObject();    // Call the placement new operator
     56
     57    object->someFunction();                                 // Do something with the object
     58
     59    object->~MySmallObject();                               // Call the destructor
     60    allocator.free(object);                                 // Free the allocated memory
     61    @endcode
     62
     63    @b Important: You have to call the destructor of the object manually, because this
     64    is not automatically done by the allocator nor free().
     65
     66    @note The destructor can be ignored if it is empty or not implemented. This saves
     67    another amount of time.
     68
     69    @remarks For a distributed usage of SmallObjectAllocator it may be a good idea to
     70    create a static function that returns an instance to it. The allocator then works
     71    like a singleton and can be accesses from everywhere.

     41    @ingroup Util String
     42    @brief a small class to get the parts of a string separated by commas
     43
     44    @anchor SubStringExample
     45
     46    The class SubString can be used to split an std::string into multiple tokens, using
     47    a delimiter. SubString allows different options, for example to remove whitespaces
     48    around the delimiters or different safe-mode chars, like quotation marks and braces.
     49
     50    You can access the tokens of the SubString using the [] operator like an array.
     51    SubString also supports to join the tokens (or a subset of the tokens) again using
     52    @ref orxonox::SubString::join() "join()". It's even possible to get a subset of the
     53    SubString as another SubString using @ref orxonox::SubString::subSet() "subSet()".
     54
     55    Example:
     56    @code
     57    std::string text = "This is a test, \"Hello \\\" World\" and vector {1, 2, 3}";
     58    SubString tokens(text, SubString::WhiteSpaces, "", false, '\\', true, '"', true, '{', '}', true, '\0');
     59
     60    for (unsigned int i = 0; i < tokens.size(); ++i)
     61        COUT(0) << i << ": " << tokens[i] << std::endl;
     62    @endcode
     63
     64    The output of this code is:
     65     - 0: This
     66     - 1: is
     67     - 2: a
     68     - 3: test,
     69     - 4: Hello " World
     70     - 5: and
     71     - 6: vector
     72     - 7: 1, 2, 3
     73
     74    The string was split using the delimiter " ". A string between quotation mark is not
     75    split, the same holds for strings between '{' and '}'. Note how the quotation marks and
     76    the braces were removed from the tokens, because the corresponding argument is 'true'.
     77
     78    Also note that the comma after "test" in token 3 is still there - it is neither part of the
     79    delimiters SubString::WhiteSpaces nor part of the delimiterNeighbours parameter, so it
     80    remains a part of the token.
