i have treenode class defined so: class treenode<t extends myclass> { public t element; public treenode<? extends myclass> parent; public arraylist<treenode<? extends myclass>> children; } i know if there easier way restrict treenodes generic type variables extend myclass ? having write out arraylist<treenode<? extends myclass>> tedious. can't arraylist<treenode<t>> because tree cannot contain nodes different inheritance of myclass. i tried this: public static const class node_class = treenode<? extends treenode>.class; don't think can use generics part of class object. someting synonymous c++'s typedef guess, i.e. typedef treenode<? extends myclass> nodeclass; since comment seemed you, i'll post answer: i don't see point of using generics if t doesn't match between nodes in tree. given that, element should myclass .

i know references syntactic sugar, code easier read , write. but differences? summary answers , links below: a pointer can re-assigned number of times while reference cannot re-seated after binding. pointers can point ( null ), whereas reference refer object. you can't take address of reference can pointers. there's no "reference arithmetics" (but can take address of object pointed reference , pointer arithmetics on in &obj + 5 ). to clarify misconception: the c++ standard careful avoid dictating how compiler must implement references, every c++ compiler implements references pointers. is, declaration such as: int &ri = i; if it's not optimized away entirely , allocates same amount of storage pointer, , places address of i storage. so, pointer , reference both occupy same amount of memory. as general rule, use references in function parameters , return types define useful , self-documenting interfaces. use ...

we're using require , browserify, single-function modules imported this: var loadjson = require('../loadjson'); and used this: x = loadjson(url); i'd spyon loadjson function, doesn't seem possible. it's not global function, doesn't work: spyon(window, 'loadjson') it's not local function, doesn't work: loadjson = createspy('loadjsonspy', loadjson).and.callthrough(); when require module jasmine spec, function visible inside closure, that's not same closure other module using loadjson real. so in short, think it's not possibly use spyon in case - correct? creative workarounds? if loadjson singleton, can this. var functionstospyon = {loadjson: loadjson} spyon(functionstospyon, 'loadjson') this workaround used when had same problem.

some books claim used ansi c , use turbo c compiler run these example. tried run these on linux found these example windows. #include<stdio.h> #include<conio.h> /* #include<dos.h> */ int main() { int a; clrscr(); scanf("%d", &a); printf("%d",a); getch(); return 0; } can call above example ansi c? why or why not? as @milevyo said, functions implemented borland's compilers. on windows can replace clrscr() system("cls") , getch(); _getch(); or, better, getchar() .
