gwt - how to use eventBus.removeHandler in mvp4g? -


i wanted delete/clear instances of presenter before firing event. documentation says use eventbus.removehandler(handler), not figure out how handler object presenter class

presenter has multiple=true attribute set.

if have declared presenter "multiple="true"

@presenter(view=oneview.class, multiple=true) public class onepresenter extends basepresenter<ioneview, oneeventbus>{...}

you add presenter eventbus calling:

onepresenter presenter = eventbus.addhandler(onepresenter.class);

and remove presenter calling:

eventbus.removehandler(presenter);

here find documentation:

https://github.com/frankhossfeld/mvp4g/wiki/04.-defining-presenters,-views-&-services#multiple-presenter

in mvp4g can activate , deactive presenters activate/deactivate attribute of @event annotation. (https://github.com/frankhossfeld/mvp4g/wiki/03.-defining-eventbus#activatingdeactivating-presenters)

if need control before presenter handles event, can override onbeforeevent-method. (https://github.com/frankhossfeld/mvp4g/wiki/04.-defining-presenters,-views-&-services#on-before-event)

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.
