using maven, there couple of plugins support e.g. generation of jaxb classes xsd, e.g. org.codehaus.mojo:jaxb2-maven-plugin , org.jvnet.jaxb2.maven2:maven-jaxb2-plugin. newest version of have dependencies e.g. org.glassfish.jaxb:jaxb-xjc , org.glassfish.jaxb:jaxb-runtime (in version 2.2.11). but wonder happen if used generate classes xsd use jdk 8 (which contains version 2.2.8) @ runtime: wouldn't there risk runtime errors? so necessary or recommended use jaxb-runtime corresponding jaxb-xjc version used generate classes xsd? of course override dependencies jaxb-xjc etc. , explicitly use version 2.2.8. wonder if same result if used jdk 8 xjc tool directly? you have 3 phases: (1) generation of schema-derived code (2) compilation of schema-derived code (3) runtime the important jaxb api use compile (2) compatible jaxb api use in runtime (3). if not case might compile code uses annotation later not available in runtime. , you'll see error first in runtime.

if using laravel 4.2 caching mechanism bellow. $users = db::table('users')->remember(10)->get(); as understand cache mechanism query execute one's , story it's value cache , return data cache upto 10 minutes. but problem one's query executed , data stored it's cache inbetween user table updates it's value how may check , update cache value can updated data. any 1 have idea suggestion please let me know...? if using supported cache driver , can add tags caches: $users = db::table('users')->cachetags(array('people', 'authors'))->remember(10)->get(); then when value updated, can flush cached values under tag. example, in user model add: public function save(array $options = []) { $result = parent::save($options); if ($result) { cache::tags(array('people', 'authors'))->flush(); } return $result; }

'g' dictionary keys vertices of graph, each values vertices connected to. randomvertices gives me edge want contract, while mergevertices updates dictionary (and hence graph) deleting second vertex, updating values of keys linked vertex, , getting rid of self-loops. looks okay me if run on test graph keyerror @ l = g[x] s

i new comer of haskell , following question: given class: class myclass foo :: -> [a] then have subclass more specific: class (myclass a) => subclass foo param = [bar param] bar :: -> but doesn't work expected. expecting default implementation setup in definition of subclass doesn't. need define instance myclass seperately, sounds stupid. how can achieve default implementation when know subclass satisfies property definitely? more specifically, want express in haskell, when class satisfies properties, functions parent can have default implementation . in example, subclass has property bar such know foo defined in such way. a more general form of question is, idea reuse using classes , instances? i found post: inclusion of typeclasses default implementation in haskell it's quite close, still not answering question totally , forms little bit different. elaborating on daniel's answer: suppose have new datatype myda

i have code in have started timer tick event of 75 sec. application supposed perform task, @ time interval of 75 sec. application runs fine 5 hrs, of sudden shows not responding...whenever other operations done on computer opening other files... my code looks this: private void button2_click(object sender, eventargs e) { tmrtimer.enabled = true; } private void tmrtimer_tick(object sender, eventargs e) { //do stuff here; } i think maybe because used timer system.windows.forms.timer class. kind of timers single thread timers; means use same thread ui use. so, it's obvious why application shows not responding when thread has lots of things do. suggest change timer type , try one: system.threading.timers .

i creating automated system reads data wirelessly transmitted data excel. data sends gauge number , value ex. 89,-.002 (gauge #89, value=-.002). data goes cell f2. have created code separates the gauge number , value variables. have list of fixed gauge numbers in cell c5-c11 , readings populate offset in cells g5-g11 based on gauge number. haven't been able figure out how take readings same gauge multiple reading if needed check multiple spots on part. example if there 3 different readings needed gauge 87 ( 87 listed 3 times in c5-c11), need code search 87 based off gauge number variable input in f2 , find 87's in cells c5-c11. check if cell offset 4 columns has value already. if move on next 87 found , check if offset on 1 has value. if doesn't populate cell. i can't hard code numbers in because creating template. have search multiples gauge numbers believe. any or ideas appreciated. better if can give me sample code integrate project. set wsinput = sheet1 ws

i working in c++03 project. , i'm taking iterator template. need assert iterator references specific type. does c++ provide me way beyond writing own struct validation? what want equivalent of c++14 functionality: static_assert(is_same<iterator_traits<inputiterator>::value_type, int>(), "not int iterator"); since it's c++03 assume i'll have use assert , that's fine if it's runtime debug check need check there. c++03 doesn't come static_assert -type thing, that's c++11 feature. however, there's boost_static_assert . if boost not available you, straightforward thing write: namespace detail { template <bool > struct my_static_assert; template <> struct my_static_assert<true> { }; template <size_t > struct my_tester { }; } #define my_static_assert(b) \ typedef ::detail::my_tester< sizeof(::detail::my_static_assert< ((b) == 0 ? false : true) >)> \ my_stat
