we have wired error not reproduciable rondomly happening. throw error on line/function in jquery: proxy: function( fn, context ) {

here code trigger problem. used screen rotation, throw error in settimeout($.proxy(function... :

    _showpanel: function(index) {         // go first panel, index out of range         var index = (index > this._panels.length - 1) ? 0 : index,          // calculate next panel index             nextindex = (index + 1) % this._panels.length,             panel = this._panels[index],             oldpanelelement = this._currentpanelelement;           // set timer when switch next panel         this._panelrotationtimeout = **settimeout($.proxy**(function () {             if (this && this._showpanel) {                 this._showpanel(nextindex);             }         }, this), panel.time);           // hide old panel         if (oldpanelelement) {             oldpanelelement                 .hide()                 .detach();         }          // show/hide animation         if (panel.animation) {             this._animation.show();         } else {             this._animation.hide();         }          // show new panel         this.element.find('.panelcontainer')             .append(panel.element);         panel.element.show();          // update status , button         this._updatedisplay();          // track current panel details         this._currentpanelindex = index;         this._currentpanelelement = panel.element;          this._currentdevicestatusindex = index;     },

settimeout's first argument should function. in example you're calling $.proxy giving settimeout return value of $.proxy function. try passing anonymous function , stuff inside it:

settimeout ( function() { $.proxy ( ...

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
