c++ - Qt TcpServer architecture -

-

the question architecture of server qt. example, there slot readyread() being called when socket signals readyread() if there several kind of requests can 

void server::readyread() {    qstring msg = readfirstwordfromavaiabledata();    switch (msg){        case "ping":        case "get":  // , on    } }

i wonder there other way this. guess isn't expandable , comfortable.

if want server work client written on java, c, perl, etc should use qbytearray only, right? in samples qtdemo client sends size of message before message. necessary?

it nice if suggest me samples servers written qt (on github, bitbucket, etc). want how production servers arranged.

if each of commands have fixed length of payload, may not necessary send message length.

qbytearray convenient wrapper around unsigned char array, , has useful utility methods, it's thing use. can use qstring if protocol text-based, though aware default qstring unicode, character takes 2 bytes instead of one. can use appropriate conversion functions (qstring::fromutf8, qstring::fromascii, etc.).

i first suggest taking @ examples in qt documentation if haven't done so. don't have other examples recommend though.

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."
