java - How to get the parameter names of an object's constructors (reflection)? -

-

this question has answer here:

say somehow got object reference other class:

object myobj = anobject;

now can class of object:

class objclass = myobj.getclass();

now, can constructors of class:

constructor[] constructors = objclass.getconstructors();

now, can loop every constructor:

if (constructors.length > 0) {     (int = 0; < constructors.length; i++)     {         system.out.println(constructors[i]);     } }

this giving me summary of constructor, example constructor public test(string paramname) shown public test(java.lang.string)

instead of giving me class type however, want name of parameter.. in case "paramname". how that? tried following without success:

if (constructors.length > 0)     {         (int icon = 0; icon < constructors.length; icon++)         {             class[] params = constructors[icon].getparametertypes();             if (params.length > 0)             {                 (int ipar = 0; ipar < params.length; ipar++)                 {                     field fields[] = params[ipar].getdeclaredfields();                     (int ifields = 0; ifields < fields.length; ifields++)                     {                         string fieldname = fields[i].getname();                         system.out.println(fieldname);                     }                                                        }             }         }     }

unfortunately, not giving me expected result. tell me how should or doing wrong? thanks!

this information lost after compilation , can't retrieved @ runtime.

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
