php - How to pass an argument into call_user_func -

-

here line of code using:

$json[jsonconstant::json_custom] => call_user_func(array($this, $customtypes[$customdownloadtype])),

$customtypes[$customdownloadtype] might resolve gettags().

what do though, if want pass argument gettags() though? example, have var called $time want pass in? do?

it seems want mixture of examples 2 , 4 http://php.net/manual/en/function.call-user-func.php - possible?

thanks

call_user_func($fn, 'a', 'b', 'c'); // => $fn('a', 'b', 'c');  call_user_func_array($fn, ['a', 'b', 'c']); /// => $fn('a', 'b', 'c');

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.
