can class be static in java class d amp

    tests[i]->reset();. Here’s a simple test of the previous file:. using std::towlower;.         size_t startOfFile = findDelim + 1;.   ofstream out(“Iofile.out”);.     return seq.begin();.   init1<10,20>(a);  // must specify. }.     result.first = letters[count++];.       iterator tmp = *this;. class Left : virtual public Top {. } ///:~.   void setValue(int x) { i = x; }. TheOuter constructor contains some private data (name), and it wants to provide both aPoingable interface and aBingableinterface so it can be used withcallPoing( )andcallBing( ). Of course, in this situation wecould simply use multiple inheritance. This example is just intended to show the simplest syntax for the idiom; you’ll see a real use shortly. To provide aPoingable object without derivingOuter fromPoingable, the inner class idiom is used. First, the declarationclass Inner says that, somewhere, there is a nested class of this name. This allows thefriend declaration for the class, which follows. Finally, now that the nested class has been granted access to all the private elements ofOuter, the class can be defined. Notice that it keeps a pointer to theOuter which created it, and this pointer must be initialized in the constructor. Finally, thepoing( ) function fromPoingable is implemented. The same process occurs for the second inner class which implementsBingable. Each inner class has a singleprivate instance created, which is initialized in theOuter constructor. By creating the member objects and returning references to them, issues of object lifetime are eliminated.. For up-to-date information, visit http://hillside.net/patterns..
