C++ Pass by reference vs. pointer in a Class -


Then, I have a class that stores the pointer vector for objects. I have a method that adds objects to the vector. While adding, I know that I can pass by reference or by the indicator, and have read about the advantages and disadvantages of each, but in this case, I can not understand who is better and why.

Code> HPP: Class Room {Vector & lt; Item * & gt; item; Public: Zero Edith (item *); }; CPP: Zero Room: Added Item (Items * Item) {items.push_back (item); }

... and pass with the reference: 

  hpp: class room {vector & lt; Item * & gt; item; Public: Zero Edithum (item & amp;); }; CPP: Zero Room: Added Itam (Items and Items) {items.push_back (and items); }   
 Who should I use?   
 
 
 This is not a minor thing, so do the things that sounds more natural on the call site, or the rest Is more compatible with the code.  
 OK, I can see points in favor of everyone, but I can not tell you if they talk about your case.  
     
  •  Going through the pointer, you get to know exactly how you are using   logic (although I can not tell that this is a useful meaning. 
  •  
  •  A call site is doing something like idiots  
  •  A call site that passes through an indicator (or the result of  new ) addresses an automatic variable address  
  •    
  •  Passing through the context shows that the argument should not be  NULL , which may or may not be true And useful

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
