is code causes undefined behavior? or can run problem this? (copy full class without functions, variables public modifier , modify private memebers throw pointer) example: #include <iostream> using namespace std; class point { private: int x; int y; public: point(int x, int y) { this->x = x; this->y = y; } void print() { cout << "(" << x << ", " << y << ")" << endl; } }; struct pointhack { int x; int y; }; int main() { point a(4, 5); a.print(); ((pointhack *) (&a))->x = 1; ((pointhack *) (&a))->y = 2; a.print(); return 0; } output: (4, 5) (1, 2) (with original member order, of course) despite classes being layout compatible (see below), code exhibits undefined behavior due fact such pointer casts prohibited the c++ strict aliasing rules 1 . but: replacing casts union makes code st

here's i'm doing in service: runasync { <some work here> mydomainobject.merge() } i error saying "no hibernate session bound thread, , configuration not allow creation of non-transactional 1 here". know sure code being run asynchronously, seem executor plugin setup correctly. so tried next, thinking domain object "mydomainobject" must not bound in thread although thread has hibernate session executor plugin: runasync { <work> def instance2= mydomainobject.get(mydomainobject.id) // works instance2.field1=123 instance2.save() // fails } i same error here , interestingly, get() succeeds in bringing correct data , setting instance2. it's "save()" fails. know because i've stepped through code in debugger. finally, if following, works: runasync { <some work here> mydomainobject.withtransaction { mydomainobject.field1=123 mydomainobject.merge() }

let have these classes: class {}; class b : {} ; and function return a : public read_an_a(); since b child of a , i'd able read it's a properties in following sense: b b = new b ( read_an_a() ); (that assuming use of default copy constructor) or maybe this: b b = (b) read_an_a (); all of above broken, right way achieve that? one way of doing add constructor of b takes a, , harvests relevant parts it: public b(a a) { this.x = a.x; this.y = a.y; } your b class in best position know take, approach reasonably clean, too. lets write b b = new b(read_an_a()); like suggested in question. of course b need other constructors, too.

say class classone extends classtwo , classone subclass , classtwo superclass. if went class , typed in: classtwo hello = new classone(); mean can use methods in classone have been inherited classtwo , not methods in classone ? (e.g a. method called void eat(); in classtwo , classone inherited method void walk(); in classone , not in classtwo using hello keyword, access eat function , not walk function?), don't quite understand concept of polymorphism. can explain , giving example? much. yes true, system see classone classtwo in regards available methods. think these concept buckets, in case classone fits classtwo bucket. if put classone in classtwo bucket can see classtwo bucket. pick out classone classtwo bucket, can cast it. this helps in case of upcasting , downcasting, casting object supertype or subtype. either put item in basket(upcasting) or take out basket (downcasting). this analogy might crap helps me :) to answer question yes,
