java - Domain model that needs to store another domain model -


Suppose I have the following simple domain model setup: 

  class events. .} Class Schedule Event {event event; Date time date; ..}   
 And I want to see the events as detailed as possible, I will call it  
  class event {public zero plan (Date time date) {// Can I create and store a planned event here? // Use a repository in other words}   
 I combine the planning method, because from within the omnipresent language, you plan an event that happens in a planned event in the future. . Therefore it seems natural to put the method of planning in the event class.  
 I have always read that you should not use repostories in domain objects, I can understand why, but how do I solve the above version?  
 Does such domain events occur in the game?  
  class event {public zero plan (date time date) {DomainEventPublisher .instance (). Publish (New planned art-crafted (this, date))); }   
 Where will the domain event ensure that any planned event will be created and stored (by a repository)?   
 
 
 Is it imaginable that both events and planned gutts are the total roots? I suspect that the incident should know something about planned events, certainly not to build one - it is beyond its scope, tells Evans about factories:  
 
 When an object is formed, or the whole aggregate becomes complicated or reveals too much internal structure, the factors provide encapsulation.     
 Perhaps you use an entire factory to create a planned brick for an event, to minimize two, I'm not going through a schematic event rather than a direct object reference I like to refer to the event through some unique event-id. You can use this ID to view the event through its repository.

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...
