c++ - Filtering non-trivial loggers in Boost.Log? -


i'm trying figure out how enable simple filter in combination boost_log_sev.

for example, if set up:

enum class severitylevel {   foo,   bar };  boost::log::sources::severity_logger_mt<severitylevel> slg;  boost_log_sev(slg, severitylevel::foo) << "foo log record"; boost_log_sev(slg, severitylevel::bar) << "bar log record";

i'd able add this:

slg.set_minimum_severity(severitylevel::bar);  // filter out foo logs

the boost.log docs jump rather filtering on trivial logs more complicated cases.

first, little secret may want know reading boost log documentation, code examples more complete summaries on doc pages. if understand right should happy example

http://www.boost.org/doc/libs/1_54_0/libs/log/example/doc/tutorial_filtering.cpp

look set_filter line, , adapt to:

sink->set_filter(severity >= severitylevel::bar);

for more advanced filters asked related question on boost users mailing list:

i'm working on adding multiple querystring , doesn't seem work. i've found codes seems work others might i'm missing something. i want like: http://mydomain.com/board/?getyear=2013&getsometext2=sometext to http://mydomain.com/board/2013/sometext/ i added code below functions.php file. doesn't seem work should though. this works. echoing querystring gets both variable without problem. http://mydomain.com/board/2013/sometext/ but doesn't. tested querystring vis isset() seems nothing being set/get http://mydomain.com/board/2013/ function add_query_vars($vars) { $vars[] = "getyear"; $vars[] = "getsometext2"; return $vars; } add_filter('query_vars', 'add_query_vars'); function add_rewrite_rules($arules) { $anewrules = array('board/([^/]+)/([^/]+)/?$' => 'index.php?pagename=board&getyear=$matches[1]&getsometext2=$matches[2]'); $arules = $a

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
