i setting form typeahead. have 2 input fields next each other, , need autocomplete on each of them. html looks this: <select id="numerator"> <option value="presentation">presentation</option> <option value="chemical">chemical</option> </select> <input id="numeratorid" class="typeahead" type="text" /> <br/> <select id="denominator"> <option value="presentation">presentation</option> <option value="chemical">chemical</option> </select> <input id="denominatorid" class="typeahead" type="text" /> each of input fields autocomplete looking @ api endpoint. should of form /api/1.0/code?type=presentation&code=123 or /api/1.0/code?type=chemical&code=123 . the value of type parameter in api call should depend on value of <select> element next each

ipstoreload.filter { !contains(self.ipstoinsert, {$0.row == $1.row}) } i want expression work. need complements of 2 generic array: ipstoreload \ ipstoinsert . idea doing wrong? this definition: var ipstoinsert = [nsindexpath]() var ipstodelete = [nsindexpath]() the trouble have 2 nested closure expressions (the 1 filter , , 1 contains ). within closure expression, $0 , $1 refer arguments local closure expression – in case, writing expression contains takes 2 arguments ( $0 , $1 ), , closure argument filter looks if takes no arguments (hence swift complaining can't pass ()->_ argument filter ). try naming arguments, so: ipstoreload.filter { reload in !contains(ipstoinsert) { insert in reload.row == insert.row } }

i've posted to relevant issue on http-proxy . i'm using http-proxy express can intercept requests between client , api in order add cookies authentication. in order authenticate client must send post request x-www-form-urlencoded the content-type. using body-parser middleware parse request body can insert data in request. http-proxy has problem using body-parser supposedly because parses body stream , never closes proxy never never completes request. there solution in http-proxy examples "re-streams" request after has been parsed have tried use. have tried use connect-restreamer solution in same issue no luck. my code looks this var express = require('express'), bodyparser = require('body-parser'), httpproxy = require('http-proxy'); var proxy = httpproxy.createproxyserver({changeorigin: true}); var restreamer = function (){ return function (req, res, next) { //restreame req.removealllisteners('data

i expected non-static blocks execute @ time of object creation. in following example called static method non-static block executed. i've not created object why non-static block execute? class example { static void mark() { system.out.println("mark method"); { system.out.println("hello"); } } } public class staticobject { public static void main(string[] args) { example.mark(); } } result: mark method hello you don't have non-static initialization block in example. block inside of method code gets executed part of method. (nested code blocks introduce new scope, can create variables not visible outside of block.) it's initializer if it's within class outside of method declaration. if change code move block outside of method: class example { static void mark() { system.out.println("mark method"); } // it's instance initializer { system.out.println(&

i have 2 fragments, contain lists (listview). in second fragment, each row (despite last one) contain checkbox. last row contain different layout (text + button) - that's because want displayed after list ends (not @ bottom of screen). want achieve is: when no checkbox checked last row visible, otherwise last row invisible. haven't find solution yet.. use getchild() refers visible items. have idea? thanks! here getview method in arrayadapter: public view getview(final int position, view convertview, final viewgroup parent) { viewholder holder = null; final int last = this.getcount()-1; int thetype = getitemviewtype(position); if (convertview == null) { if (thetype == 0) { convertview = inflater.inflate(layoutresourceid, null); holder = new viewholder(); holder.name = (textview) convertview .findviewbyid(r.id.name); final checkbox checkbox = (checkbox) convertview.findviewbyid

i having trouble understanding return type constructors, professor stated ​that "a constructor doesn't return code standpoint. meaning, when declare it, don't declare return value. it implicitly returns pointer (meaning, can't change behavior), however. side note, returns 'this' pointer. of out of hands of programmer though." is saying when create object constructor passes pointer, or off here? if called "initializer" rather "constructor" make more understandable? a constructor not create object. initializes object. there nothing return. object created using new or auto or static allocation.

consider these lines of code: concurrentdictionary<string, object> error = new concurrentdictionary<string, object>(); error.add("hello", "world"); //actually throws compiler error and idictionary<string, object> noerror = new concurrentdictionary<string, object>(); noerror.add("hello", "world"); i figure out have change il make add function private. now in spirit of decoupled code i'd use interface seems concurrent dictionary isn't found of add method. is safe use add (i can't view il don't know if it's thread safe.)? or should use concrete type of concurrentdictionary<tkey, tvalue> , explicitly use tryadd . yes, it's safe. have @ reference source concurrentdictionary . method idictionary<tkey, tvalue>.add calls tryadd , throws exception if key exists. the hiding of members of interface not requires il modifications done. can done through explicit inter

i have found lot of pages config examples such as: let g:unite_source_grep_command = 'ag' let g:unite_source_grep_default_opts = \ '--line-numbers --nocolor --nogroup --hidden --ignore ' let g:unite_source_grep_recursive_opt = '' or " use ag searching let g:unite_source_rec_async_command = \ 'ag --follow --nocolor --nogroup --hidden -g ""' let g:ackprg = 'ag --nogroup --column' nnoremap <space>/ :unite grep:.<cr> unfortunately, don't understand these doing or why. i've played around , have gotten parts of want working. ideally, i'd similar ack.vim does: i hit key mapping, let's / i put in search query that opens unite.vim buffer split @ top asynchronously uses ack or ag searches search query i can navigate through results , select 1 or open in splits perhaps i'm missing spirit of question, if need configure unite ag, that's straightforward: in .vimrc add: let g

trying load phpunit dataset using: public function getdataset() { return new phpunit_extensions_database_dataset_yamldataset("/path/file.yml"); } i array_keys() expects parameter 1 array, integer given on command line. i can't tell if error because phpunit_extensions_database_dataset_yamldataset::addyamlfile() doesn't input, or if constructor returning phpunit_extensions_database_testcase doesn't like. the yaml file created using phpmyadmin's yaml export feature. else run this? the direct export phpmyadmin not match requirements in phpunit. take @ official documentation: https://phpunit.de/manual/current/en/database.html and take @ file generated phpmyadmin. differs. in phpmyadmin table names comments. you have reformat file usable phpunit.
