caching - how to use php stream to block DWOO compile the cache files everytime? -

i code thread talking blocking dwoo using php streams can't understand how use code. can tell me how use it?

recent problem:
i've got serious problem storage on web hosting because of lot of cache files created on @ cache/dwoo/compiled folder. developed website using codeigniter framework. want disable feature (auto created cache files @ cache/dwoo/compiled folder), because using lot of space on storage.

this code:

include 'lib/dwooautoload.php'; include 'dwoo/compiler.php';  $dwoo = new dwoo();  stream_wrapper_register('dwoomem', 'dwoo_template_memory_streamwrapper'); $dwoo->addresource('memory', 'dwoo_template_memory');  $tpl = new dwoo_template_memory('test.html'); $dwoo->output($tpl, array('foo'=>'foo', 'bar'=>'bar'));  class dwoo_template_memory extends dwoo_template_file {     protected $chmod = null;      public function getcompiledfilename(dwoo $dwoo) {         // no compile id provided, set default         if ($this->compileid===null) {             $this->compileid = $this->getresourceidentifier();         }         return 'dwoomem://'.$this->compileid;     }      protected function makedirectory($path)     {     } }  class dwoo_template_memory_streamwrapper {     protected static $streams = array();      function stream_open($path, $mode, $options, &$opened_path)     {         if (!isset(self::$streams[$path])) {             if(!($mem = fopen('php://memory', 'w+'))) {                 return false;             }             self::$streams[$path] = $mem;         }         $this->res = self::$streams[$path];         $this->stream_seek(0);         return true;     }      function stream_read($count)     {         return fread($this->res, $count);     }      function stream_write($data)     {         return fwrite($this->res, $data);     }      function stream_eof()     {         return feof($this->res);     }      function stream_seek($offset, $whence=seek_set)     {         return fseek($this->res, $offset, $whence);     }      function stream_stat()     {         return fstat($this->res);     }      public static function url_stat($path, $flags)     {         return array();     } }
