member

I want to create a calculated member and filter it by dimension. This is WORKING example: ( [Policy].[Policy Status].&[Void], [Policy].[Tran Type].&[Renewal], [Measures].[FK Policy Distinct Count] ) But if I want to filter it like this ( [Policy].[Policy Status].&[Void], [Policy].[Policy Status].&[Policy], [Measures].[FK Policy Distinct Count] ) Than it's NOT working. It says that same hierarchy is showing multiple times in the tuple. Another thing is, how to exclude rows? Here's the idea... ( ![Policy].[Policy Status].&[Void], ![Policy].[Policy Status].&[Policy], [Measures].[FK Policy

I have got one class with various member variables. There is a constructor and there are getter-methods, but no setter-methods. In fact, this object should be immutable. public class Example { private ArrayList<String> list; } Now I noticed the following: when I get the variable list with a getter-method, I can add new values and so on - I can change the ArrayList . When I call the next time get() for this variable, the changed ArrayList is returned. How can this be? I didn't set it again, I just worked on it! With a String this behaviour isn't possible. So what is the difference here? Just

I would like to have an array as a member of my table view controller. The array will be a data source. What are the differences or advantages/disadvantages the following ways of having a member variable array. class BinViewController: UITableViewController, WKNavigationDelegate { var peopleArray1 = [String]() var peopleArray2: [String] = [] var peopleArray3: [String]! var peopleArray4: [String]? These two basically do the same thing: var peopleArray1 = [String]() var peopleArray2: [String] = [] They declare and initialize an empty array of type [String] . These two in the other hand, are also

So below is a basic idea of what I'm trying to do. I have an external library that I would like to use in an existing project. I cannot change anything in the external library or the main function in the existing project of course. The problem I face is how to pass a callback function I make in my class to this external function as a pointer to function. At the same time, this callback function has to have access to members of the class so I cannot simply make it static. How can I do it? Class ExternalClass //This I cannot mess with. { //somestuff void ExternalFunc (void(* callback)(int, const

I have read several posts about this, but can't seem to find exactly what i am looking for with example code if anyone could give me some help i would highly appreciate it. in my header i have: void addEvent(void (*func)(Pack *)); void triggerEvents(Pack * ); std::list<void(*)(Pack *)> eventList; and in cpp file void DNetwork::addEvent(void (*func)(Pack *)){ eventList.push_back(func); } void DNetwork::triggerEvents(Pack * pack){ for (std::list<void (*)( Pack *)>::iterator it = eventList.begin(); it != eventList.end() ;it++ ){ (*it)(pack); } } This works fine with free functions, but when i try

I'm writing a hash class: struct hashmap { void insert(const char* key, const char* value); char* search(const char* key); private: unsigned int hash(const char* s); hashnode* table_[SIZE]; // <-- }; As insert() need to check if table[i] is empty when inserting a new pair, so I need all pointers in the table set to NULL at start up. My question is, will this pointer array table_ be automatically initialized to zero, or I should manually use a loop to set the array to zero in the constructor? The table_ array will be uninitialized in your current design, just like if you say int n; . However,

I would like to implement 'GetParent()' function in here- class ChildClass; class ParentClass { public: .... ChildClass childObj; .... }; class ChildClass { friend class ParentClass; private: ChildClass(); public: ParentClass* GetParent(); }; I've tried to create a private member variable which stores pointer to parent object. However this method requires additional memory. class ChildClass { friend class ParentClass; private: ChildClass(); ParentClass* m_parent; public: ParentClass* GetParent() { return m_parent; } }; So I used offsetof() macro (performance costs of calling offsetof() can be
