java - Hazelcast ConcurrentMap / MultiMap Key -


I am declaring a multimate and want to know whether it is a good idea to keep the key in the form of an integer string As the key will accelerate to retrieve the values ​​with the key? 

  Multimap & lt; String, order & gt; MmCustomerOrders = hz.getMultiMap ("Customer Order");   
 versus  
  multimap & lt; Integer, order & gt; MmCustomerOrders = hz.getMultiMap ("Customer Order");   
 thx.   
 
 
 It may be slightly faster, encoding / decoding simple ASCII strings based on string length and complexity It's easy to do but if you have non ASCII characters then it will be a bit more complex. But even on integers there is a high chance that you have to keep making the whole thing since the values ​​are high, if you override the default integer cache size you can work around it (java. Lang.Integer .IntegerCache.high ". This increases the size of the integers before determining more than 127.  
 The question in the reality is that if you make real speed difference, then the serialization It just depends on the more I just try that there is no difference to you, otherwise I will see it as a timely adaptation. This will be different if your objects are very complex but do not give you real benefits for string and integer

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...
