javascript - Prepend argument to arguments then apply -


I have a function, message which takes an overview to define the message type And then 

  is added to any other argument to create a message for the function message (type) {var msg = _.rest (arguments), purely an undisputed one.  
 Add (""); // will actually be used to set a type of div on div / but I'm just using console.log so that it can be as simple as ever. Console.log (type + ":" + msg); }   
 I want to provide helpful tasks,  error ,  warning ,  information , which just call With the right type, I am just unsure about the best way to go about this. I can think of two ways but I am not sure I go about it in the right way. Or maybe I want to finish things.  
 The first path seems a little unnecessary, creating a new array, the first argument and logic are flat.  
  Message. Now (this, _. Fleeton (["error", logic]));   
 The other way seems a bit ... messed up?  
  Array.prototype.unshift.call (logic, "error"); Message.apply (this, arguments);   
 Although using my:  
  (function () {Array.prototype.unshift.call (logic, 0); console, log (logic) ;}) (1, 2, 3);   
 I get the following output:  
  [0, 1, 2, 3, undefined, undefined, undefined, ..., undefined]    
 
 
  var args = Array.prototype.slice.call (argument); // argin args.unshift ("error") create the actual array; Message.apply (this, args);

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...

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...
