java - Eclipse - `open call hierarchy` stop searching in lambda chain -


here sample java code:

public class test {      public static void main(string[] args) {         methoddepth0(             ()->                 methoddepth1(                     ()->                         methoddepth2()                 )         );     }      static object methoddepth2() {         return null;     }      interface myif {         void call();     }      static void methoddepth0(myif myif){         myif.call();     }      interface myif2 {         void call();     }      static void methoddepth1(myif2 myif2){         myif2.call();     } }

when open call hierarchy of method methoddepth2() eclipse(4.4), open call hierarchy stop searching next caller: open call hierarchy stop searching next caller method

what expect opening call hierarchy of method methoddepth1() show until main method. opening call hierarchy of method <code>methoddepth1()</code> show until <code>main</code> method

from can tell lack of call hierarchy depth due (re)evaluation of code @ runtime. explained in 15.27.4 run-time evaluation of lambda expressions in java language specification.

at run time, evaluation of lambda expression similar evaluation of class instance creation expression, insofar normal completion produces reference object. evaluation of lambda expression distinct execution of lambda body.

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.
