java - How to prevent Hibernate load the whole collection? -


उदाहरण के लिए, मेरे पास निम्न इकाई है: 

  वर्ग उपयोगकर्ता {... निजी प्रश्न सेट करें; ...}   
 जब मैं डोमेन मॉडल संचालित करता हूँ:  
  user.questions.add (...);   
  हाइबरनेट  इस संग्रह के सभी प्रश्नों को लोड करेगा, भले ही मैंने संग्रह को  LAZY  पर सेट किया हो। मैं इस व्यवहार को कैसे बदल सकता हूँ?   
 
 
 तो वास्तविक समस्या का वर्णन: जब मैं कैस्केडिंग लागू करता हूं, तो एक प्रदर्शन समस्या है क्योंकि कई सवाल हो सकते हैं।  
 मेरा जवाब तब होगा: फिर प्रश्नों को बचाने के लिए कैस्केडिंग का उपयोग न करें, एक नियमित EntityManager.persist () कॉल का उपयोग करते हुए सवाल जारी रहें।  
 बहुत स्पष्ट, सही?

ios - Does Core Data autoupdate a many to many relationship on saving -

I have used 2 database tables and core data / NSManagedObjects in SQLite: User is user_id name group (multiple groups) Group group_id title group members (multiple users) By using core data to save a group and adding users ( Add to group) as follows: group * cordata = zero; Cordata = [NSEntityDescription insertNewObjectForEntityForName: @ Managed Object Contains in "Groups": Reference]; Request = [NSFetchRequest fetchRequestWithEntityName: @ "user"]; Request.predicate = [NSPredicate predicateWithFormat: @ "user_id =% @", user_id]; Result = [reference executeFetchRequest: request error: & amp; Error]; CoreData.group_id = group_id Cordettitle = Title [Cordata AdGroupMailersObject: [Last objections result]]; Is it right to say that core data manages a user with multiple users and groups with the code above? Yes, if the relationships are in the form of each other's inverse relationship The inverse relationships are updated automaticall...

Calling a C++ function from C# by passing a string with variable size to it -

I am calling a string with a C + code and calling from the C # code. The C ++ function is responsible for filling the string material. The following code is: C #party: var abc = new string builder (4096); // will have to change this var result = Basic methods. SignCrcFile (ABC); C ++: bool __cdecl SignCrcFile (char * abc) {... char * tempStr = "hello all"; // for example // copy it to ABC string strcpy (ABC, tempStr); Back true; } The problem is that tempStr's size in the C ++ function is dynamic (the above assignment for TempStr is only an example). In such a case, it is not a hard code that the size of ABC string is in the size of 4096 bytes on the C #. The first solution can be a solution to create 2 functions on the C ++ side to get the size of the string. Then allocate that size using StringBuilder in the C # side then use the next function to bring the entire string from C ++ to the C #. But no suggestion this may not be the most optimal way? ...
