java - EclassImpl setEPackage() -


i need work emf code without having clue how works. code uses ecoreutil.copy(...) clone classes. added eclass class created this:

    eclassimpl c = (eclassimpl)ecorefactory.einstance.createeclass();     system.out.println(c.getepackage().getefactoryinstance());

and overrode estaticclass() this:

    @override     protected eclass estaticclass() {                eclassimpl c = (eclassimpl)ecorefactory.einstance.createeclass();         return c;     }

now have problem, copy routine tries use:

    eclass.getepackage().getefactoryinstance().create(eclass);

which returns nullpointer exception, since getepackage() returns null. unfortunatly there seems no setter epackage, how set it?

had same problem. see in http://emfjson.org/docs/ how use api example.

samplepackage .geteclassifiers() .add(userclass);

this add class package , vice versa.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
