i have spring app using hibernate , spring data jpa's crudrepository . seems work if data queried exists in database. however, if there query returns no result, crudrepository returns null , nullpointerexception . example http://localhost:8080/api/id=3 if there row id 3 in database works fine. if there isn't row id of 3 fails a: there unexpected error (type=internal server error, status=500) on client side , nullpointerexception on server side. what proper way of dealing simple case of "no results" query? inspect return value, if it's not null , return representation of 200 ok response. otherwise, return 404 not found . in end, have controller like: @requestmapping(...) public responseentity<?> getone(...) { something = repository.findone(...); if (something == null) return responseentity.notfound().build(); return responseentity.ok(something); } can refactor preceding code incorporate java 8's opti

i have class a takes class b template argument, , need b 's constructor in order (somewhat pseudocode): class a(b) { import std.typecons : tuple; import std.traits : parameters; tuple!(parameters!b) _args; this(parameters!b args) { _args = args; } } to store arguments constructor , later construct object of class b arguments stored in _args . this pretty command pattern. is there way constructor of b parameters ? or there better way achieve deferred object construction? yes, constructor's internal name __ctor : class c { this(int a, string b) { } } import std.traits; pragma(msg, parameters!(c.__ctor)); this outputs: (int, string)

i add div scrollable background, may find script have here . i have problem because when add box, it's being drawn window canvas, draw background #wrapper , , stay in exact spot div being added. for instance, if click in position (eg. images[0]), drawn around top right corner. however, when started scrolling background, added div stay in same position. div drawn @ images[0] is, , if start scrolling, still drawn @ position of images[0]. in css, tried assigning width 100% #wrapper below, still doesn't work... #wrapper{ width: 100%; } hence, know if problem in js or css... thank :))) when place absolute div(s), make sure placing within parent position set relative . can reliably control position of absolute child divs. there no issue javascript. simply set position:relative #wrapper div. should work expected. see fiddle : https://jsfiddle.net/davidsekar/38ebkd05/

i have class objects extensively used using shared_pointers. however, want track usage of these objects , when refcount goes particular value want delete object. how can ? thinking of overriding shared_ptr's destructor can decrement refcount when every shared_ptr reference goes away. however, looks not possible. alternatives ? you wouldn't want because if refcount greater 0 means there still pointers pointing object out there, intending access it. if wanted that, you'd have make own shared_ptr class, i'd add functionality checking if pointer still valid since might disappear on people.

is there way information during or after compilation parts of code have been optimized out, without looking @ assembly or executing code. it'd nice know if big code chunk gets optimized away. gcc -s will output assembly code have been passed assembler (and been linked executable). if squint right way (and patient), can work backwards confirm whether given bit of code has been included in executable, or optimized away. obviously not you'd unless have suspicion going on, given time , effort required...

for example, list of random numbers: >>> x = [1,24,5,1,5,1,23,6] >>> heapq.heapify(x) [1, 1, 1, 6, 5, 5, 23, 24] why arbitrarily 6,5,5 , not 5,5,6 or 5,6,5? python docs contain following description of heapq : heaps binary trees every parent node has value less or equal of children. implementation uses arrays heap[k] <= heap[2*k+1] , heap[k] <= heap[2*k+2] k , counting elements zero. sake of comparison, non-existing elements considered infinite. interesting property of heap smallest element root, heap[0] . you can verify example data: >>> in xrange(len(x)): ... print '{0} <= {1}'.format(x[i], x[i*2+1:i*2+3]) ... 1 <= [1, 1] 1 <= [6, 5] 1 <= [5, 23] 6 <= [24] 5 <= [] 5 <= [] 23 <= [] 24 <= [] for more information binary heaps can check wikipedia .

i have windows forms application uses file.move move files in response user request. not asynchronous method, when destination on same drive happens instantly (i assume because can rewrite header , not move anything). however, blocks application if destination not on same drive. not desirable. so naturally thought switching async. looks way use file streams , use stream.copytoasync before removing original. that's fine, except if is on same drive, lot of wasteful copying. is there reliable way determine if proposed destination file on different drive drive stored on before deciding operation perform? @ drive letter, seems kind of hacky , think there cases junction points not work correctly. another possible choice use task.run(() => file.move(x)) , although have vaguely bad feeling that. i think best effort going comparing volume serial numbers. getfileinformationbyhandle() able volume serial number of file handle. ymmv raid / striped volumes, if ap
