c++ - How to determine type compatibility for a mixin template of a non-polymorphic type -

-

If I have a mix that is defined ... 

  template & Lt; Class T & gt; Classroom Mixin: Public T {// Mixing Methods and Members};   
 ... and declare it with a non-categorized square t ...  
  mixin < NonPoly & gt; Mixin;   
 .. and then it has a base class indicator ...  
  non-polly * non-polip = and mixin;   
 ... can I make sure later that the non-yellowpeeter is pointing to a mixin type?  
  Dynamic_cast  Mixine * & gt; (Non-POLPT)   
 is not compiled above because the base class is non-polymorphous.  
 I noticed that there are some specialty classes in Boost that can help, but I hope that is a simple solution.   
 
 
 I think you're looking at the wrong requirements. You do not need to do any casting here, but you may need some restructuring of your code. If you have a relation of class A, which makes a mixer and B uses non-poli, then pass B to the nanopoly pointers and use the mixin directly in A. There should be no reason to leave the information of type A to get it back again If there are more classes, separate those people who know the mixin and those who know the non-husband, and this one Is the only relationship  
 And it is very likely that if it is in the first place, then the mixing design is not an appropriate perspective. Many times, the use of blends is done when simple prevention is required. In my example with the above A and B, you may have a mixine class  
  template   
 and then pass the object when it should be turned on or even more general, if you are just passing a tee third party library, then you do not need a mixer at all is. Control can not be the best. The best way to keep encapsulation is to always write a file-scope algorithm, when you can manipulate Type T through the public interface and public third party operating system.  
 If you can tell that why you feel you need to lose type of information and recover later, we may be able to show more clearly how you own You can reorganize so that there is no need to do this, but such information never leaves a runtime (since you are looking to insert - your question means serial or something Minister is not getting), I can assure you that some of the design where the type of information that went not lost in the first place.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

memcached - Django cache performance -

-
We are now using Redis for in-memory cache for our Django application (we used the first memcatch The difference in performance is no big, and we're using Redis because the disc dump feature). The problem is that Django cache's performance in my view - terrible, we have a view with 102 cache hits (no miss), and it has 81 ms (only the cash part, which is with the DJBugBug toolbar Is measured). In my opinion - this is a very long time, I know, asking for a question for DB can be 10x more (or 100x) time, but that is also not good with cash performance of that fact. We are running radis (and the first memacatch) on different hosts, connected to the local network with other servers. Is there a way to maximize cache performance in Django? Instead of displaying problem cache, there is a possibility of the number of items to be received for each page 102 Cash calls mean long time lost due to network latency. With full control of the code, you may be able to fix it with m...
