objective c - CoreData - Refreshing an object doesn't change registeredObjects count -


I want to clear some of the memory that releases unused managed objects from context.

I prefer not to use reset and I want to release single objects using this function: 

  [self .managedObjectContext refreshObject: alarm mergeChanges: no];   
 Now, if I enter  registered object count  after this code, then nothing seems to have changed. I still get the same number of items that I have before the call.  
 To help you understand just about the example, this model is a simple description: With a reminder a specific task list Therefore, there are work items and alarm objects related to those tasks. There may be more than one alarm in any work  
 And here is the code, which generates this problem:  
  alarm * alarm = [NSTTAscription Includes New ObjectForternName : Managed object contexts in ENTITY_ALARM: self Management object contexts]; Self.task.alarm = [NSSet set with object: alarm]; [Self saving] [self. Managed Object Contex Refresh Object: Alarm Merge Changes: No];   
 Since I am looking for detail in  Task , I'm not interested in keeping the  alarm  object in memory.  
 
  My questions are:   
  1)  After the call, the count of registered objects does not change < Code> refresh object   
  2)  Is this a good practice? Or should I go with the reset, avoiding leaving single objects?  
 
  
 
 
 
 Why not count the registered objects after calling the referring object   
 Because you are not removing it, you are turning the object to error (hence its information is removed from memory but not disc).  
 
 Is this good practice? Or with reset, should I go to avoid leaving single items?   
 Resets the in-memory presentation of all the objects in the context - you generally do not want to do this, the refreshing object considers valid, is just one mistake, refreshing means that You must drop all references to any object in that context because they are invalid and can not be used again (you have to refresh them).  
 Generally, refreshing is a good way, but only if you need to keep the context of the object and the object description is not often needed if you do not need an object, Instead it should be left.

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...
