scala - Spray.io - delegate processing to another actor(s) -


I apply a REST service using spray.io frameworks. Such a service should receive some "search" queries, take action on them and return results to the customer. Code which has been discovered in different actor - search, after receiving the query from the user (JSON), I send this query again from my search engine (using the Ask Pattern) but I do not really understand that This is how I should apply the conversation between the spray.io route actor and my SearchActor.

I look at many variations here, but which one is more correct and why?

  1. Create an example of a search operator at startup and send every request to this actor <
  2. Create the pool of the search actor actor at the startup and send the request to this pool
    class = "post-text" itemprop = "text">

    You have not been forced to use the pattern to ask In fact, This will create a thread for each of your requests and probably is not what you want . I recommend that you use a tell instead you do this by spreading a new actor for each request ( less expensive than the thread ), which has RequestContext in one of its constructor fields. You will use this reference to return the feedback, usually with its complete method.

    Example code. 

      class RESTActor HttpService {val path = path ("Mypath") ~ Post {unit (like [SearchActor.Search]) {search = & gt; CTX = & gt; SearchX (CTX)! Search}}} case class SearchActor (ctx: RequestContext) {def receive = {case msg: search = & gt; // ... case message of search process: result = & gt; Ctx.complete (msg) // sends an answer back}}

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

java - JPA TypedQuery: Parameter value element did not match expected type -

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
