scope - Using Instance Variables Across Modules in Ruby -


Here is an example of a script that I want to be able to support: 

  Class testing includes dialect url_is 'http: // localhost: 9292' end = page = test.new @page.view   
 Here are some things to note:  
     
  1.  I am including a speech module (code is shown below.)  
  2.  I am calling the url_is () method directly on the class.  
  3.  I'm going to set a @URL variable to see a view (example) on an example of class   
     method () method that ideally looks like that variable Will be able to read. This is the code that I do not seem to be able to do this here is the code which supports the above script:  
      Module Bid Module Generator Module Accoreration DRF URL_IS (URL) @url = URL and End End Module Dielect DRF self.included (collar) collar. Delint :: Expand the Generator :: Stop the End Def "# {@ url}" End End   
     Here you can see that when the bid is spoken, The way inhibition module that sets the frequency variable to url_is () and url_is () sets the frequency variable, you can see that I can define the view () which I want to be able to reach that variable.  
     This is the latter part that is not happening, why do I get it that I am trying to read a variable from the Diode :: Generator :: Attribution module in the Bid module, but I'm not sure How is this the best way?  
     I has been tested, but I have not got anything, the situation I am describing with, I can decide with it.   
     
     
     I think you can type  class example variable   @view < / Code> are being confused by  
     When you use an instance variable, then "example" to  itself  is an example method, the example of class   You would expect). In a class, there is a  self  class (an example of  class )! This difference should be clarified:  
      class Foo @x = 0 DR RR RR RR RF self.x xx end def xx end end Foo.x # 0 Foo. New .x # 1 Foo.x # still 0, they are completely different variables   
     when you  bids :: generator :: unbreakable ,  Url_is  has been added as a class method for  test , hence an example for  @url  for  test  Setting as variable. But when you are added as an example method for  colloquial ,  view  to  test , then  @url  In the  view  method for entering  example     for  example  , you specify only You can class version that requires  
      def see self.class.class_eval {"# {@ url}"} end

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...
