javascript - Is it possible to pass the result of a promise as an argument to IIFE -

-

i have been refactoring old code uses iife fetch , initiate set of values.

var exampleinitiate = (function exampleinitiate(){   ..call backend service })();

now, per new requirement, have call same iife argument, , argument result of promise invoked later. understand iife invoked, , if result of promise, able call iife again? understands iifes run once only.

i thinking best not use iife here not fit here in case. correct, or there indeed way call iife passing argument value promise?

you can have couple of options if understand correct. first can pass argument iife this: 

var mypromise = getpromise();  var exampleinitiate = (function exampleinitiate(promise){   promise.then(function() { ... });   ..call backend service })(mypromise);

but wouldn't call way clear. suggest erase iife , use promises do: 

getsomebackendresponse().then(function (data) { ... })

edit: if iife returns promise yes, think can't pass in result of function again, since iife invoked once. rethink logic of chunk of code.

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.
