Redesign using State Design Pattern -doubts -

-

i want redesign code using state design pattern. states belong specific objects.

example:

class can have 3 states: st1, st2, st3.

similarly, class, b, can have 2 states: st4, st5.

there case class c has 1 state: st1 , st4 , st5.

basically these states should interchangeable in case of complex objects.

also, these classes a, b, , c contain data specific them used states.

my question is: how should state machine designed? should there individual sm every class? can states have common base interface?

please me out; can ask me more questions if need more info.

my question how should state machine designed ,should there individual sm every class ?

if understand description, answer "yes", each object require own state machine.

can states have common base interface ?

a common interface implies common api multiple implementations. common methods each state have, , how implementations differ state?

you may not need class each state if there's no different behavior. may have state class , fsm manages collection of states , rules govern transitions.

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."
