polymorphism - c# List of derived class -


i'm developing c# winform application work, i'm stuck , don't know best way proceed on. here's snippet of code

class block() {    // generic block properties }  class ablock() : block {     // specific ablock stuff }  class bblock() : block {     // specific bblock stuff }   abstract class algorithm() {    // generic algorithm properties    abstract list<block> blocklist // ?? }  class aalgorithm() : algorithm {     // specific aalgorithm stuff     list<ablock> blocklist // ?? }  class balgorithm() : algorithm {     // specific balgorithm stuff     list<ablock> blocklist // ?? }

i think situation pretty simple: every derived class of algorithm has it's own derived class of block, want make generic , accessible list<block> blocklist in asbtract class algorithm. think it's common situation , i'm sure there solution.

thanks in advance

i might missing something, couldn't make abstract property?

abstract class algorithm() {    abstract list<block> blocklist { get; } }

... when, writing class derives algorithm, won't compile unless blocklist.get implemented:

public class algorithma : algorithm {     public override list<block> blocks     {                 {             return new list<block> { new ablock(), new ablock() };         }     } }

about blemish that, if code within algorithma wants use blocks property, might need cast (ablock).

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...

during login process of laravel spark need request token of remote api. api stores exact same users , passwords laravel spark application. therefore need username , non hashed password of user during authentication process. i thought overriding authenticated method solution problem. in routes/web.php override post /login endpoint , pointing endpoint own logincontroller: <?php namespace app\http\controllers\auth; use illuminate\support\facades\log; use illuminate\http\request; use laravel\spark\http\controllers\auth\logincontroller sparklogincontroller; class logincontroller extends sparklogincontroller { /** * create new login controller instance. * * @return void */ public function __construct() { parent::__construct(); } /** * handle successful authentication attempt. * * @param request $request * @param \illuminate\contracts\auth\authenticatable $user * @return response */ public fu...
