Loop through an array consisting of numbers and strings, but return sum of only numbers ActionScript -

this should pretty basic, there aren't many tutorials actionscript out there. javascript close, can't find how either. want able have mixed array consisting of string , number data types, loop through array , sum of numbers while ignoring strings. example array: var myarray:array = [13, 10, "blah", 5, "eh", 10, "twenty", "thirty"]; something following should trick: var total:number = 0.0; (var i:int=0; i<myarray.length; i++) { if(myarray[i] number) total += myarray[i]; } trace(total);

cocoa touch - Macro Recording in iOS -

is possible record set of touch events on iphone , playback? have searched alot not find answer. if possible, can explain example. m not looking testing purpose. within application, instead of creating animation, want record set of events , want playback explain app flow users. regards. recording pretty simple. @ various " responding touch events " , " responding motion events " methods on uiresponder . create own uiview subclass (since uiview inherits uiresponder ) , keep copy of events passed relevant methods. playback bit more complicated; there's no way make uitouch or uievent objects (so can't make fake event , pass on -[uiapplication sendevent:] ). but, there's nothing stopping manually parsing array of event objects , handling on own (aside being kind of ugly code).

hql - NHibernate and custom SQL subquery (using temp table) -

is possible use custom sql sub query "in" parameter. currently, build sub query (subqueryestate) it's complicated chunk of sql can take time process larger datasets. code generating query using our existing sub query follows: session.queryover(() => calias) .withsubquery.whereproperty(x => x.cpe.id).in(subqueryestate) .joinalias(x => x.costs, () => acosts, jointype.leftouterjoin) .joinalias(x => x.open, () => aopen, jointype.innerjoin) .list(); to improve speed of execution have idea use temp table (transactional life-cycle) populate id's. idea either join temp table or use simpler sub query (select id temp_table) instead of more complicated original. can use table isn't mapped sub query in nhibernate? can write custom sql or create detached criteria pass parameter in clause? preserve fact nhibernate producing correct sql remainder of query. ideally like: session.queryover(() => calias) .withsubquery.whereproperty(x => x.cpe.i

synchronization - Can one explicitly lock/unlock implicit synchronized lock on an object in java -

-
yes synchronized locking synmtax easy because of it's block structure can't use it. there way explicitly lock , unlock "synchronized" monitor on object compatible prior usages of "synchronized" ? class myobj { object locker_ = new object(); void lockedmethod() { synchronized(locker_) { .... } } iterator locktraversal() { explicitlywaitforandacquirelock(locker_); // assume not throw exception return(getaniterator()); } void unlocktraversal() { explicitlyreleaselock(locker_); } } myobj obj = (...) try { iterator = obj.locktraversal(); for(;;) // iterate } { obj.unlocktraversal(); } of course in example "closures" eliminate need, "stack scoped" destructors ;^> ... you can't on object's intrinsic lock, can use java.util.concurrent.locks.lock instead. if need it, feeling risky, , aren't worried portability, can

Matlab: how to write a vector of a few points as a continuous function? -

-
i have 2 vectors: x = [0; 1; 2] y = [2.0000; 0; -14.7781] if plot x , y see 3 points on xy -plane. want connect 3 points , them continuous function: y = f(x), y(0) = 2; y(1) = 0; y(2) = -14.7781; y(0.5) = value between 2 , 0. for example y can treated zoh (zero order held) continuous signal. i saw matlab has function called d2c , converts model discrete continuous time. have no idea how link vector have already. how matlab? ok, latest edit improves situation lot. however, still not demarcate problem sufficiently. zoh simple >> x = [0; 1; 2]; >> y = [2.0000; 0; -14.7781]; >> f = @(new_x) y(find(x <= new_x, 1, 'last')); >> f(0.5) ans = 2 however, not think mean, y(0.5) = value between 2 , 0 part of question indicates. perhaps want linearly interpolated value: >> f = @(new_x) interp1(x,y, new_x); >> f(0.5) ans = 1 or cubic splines interpolation: >> f = @(new_x)

c++ - Why can't a struct be passed as value as template non-type parameter? -

-
non-type template parameters ones aren't types , example: template<int x> void foo() { cout << x; } there other options int in case, , i'd refer this great answer . now, there's 1 thing bugs me: structs. consider: struct triple { int x, y, z; }; triple t { 1, 2, 3 }; template<triple const& t> class foo { }; now, using normal nontype reference semantics, can write: foo<t> f; what's worth noting here t can't constexpr or const , because implies internal linkage, means line won't compile. can bypass declaring t const extern . might bit weird, 1 made me wonder why isn't possible: foo<triple { 1, 2, 3 }> f; we decent error compiler: error: triple{1, 2, 3} not valid template argument type const triple& because not lvalue. we can't specify triple in template value, because that's disallowed. however, fail understand real problem small line of code. what's reasoning behind not

this question has answer here: htaccess mod_rewrite [closed] 2 answers how can redirect using htacces from: http://www.example.com/directory/wp-login.php?action=register to: http://www.example.com/sitemap.html you'll need use rewrite condition match against %{query_string} variable (which action=register in example), , match against uri in rewrite rule (which directory/wp-login.php in example). it's pretty straightforward. rewriteengine on rewritecond %{query_string} ^action=register(&|$) rewriterule ^directory/wp-login\.php$ /sitemap.html? [l,r=301] these in htaccess file in document root, preferably before rules may have in there.

according http://developer.android.com/guide/components/loaders.html , 1 of nice thing loader that, able retain data during configuration change. they automatically reconnect last loader's cursor when being recreated after configuration change. thus, don't need re-query data. however, doesn't work in scenarios. i take following simple example. fragmentactivity , hosting fragment . fragment owns asynctaskloader . the following 3 scenarios work pretty well. during first launched (ok) 1 loader created, , loadinbackground executed once. during simple rotation (ok) no new loader being created , loadinbackground not being triggered. a child activity launched, , button pressed (ok) no new loader being created , loadinbackground not being triggered. however, in following scenario. a child activity launched -> rotation -> button pressed (wrong) at time, old loader's onreset called. old loader destroyed. new loader created , new l
