Performance cost of creating array of constants as function argument


Performance cost of creating array of constants as function argument

I hope this helps . No, the array will be allocated every time. Probably not a big deal in average situations, but could pretty well be in a tight loop, or if called very often (like on a busy server, etc.).
In summary, if you suffer here, it is best to put your typical delimiter arrays in a helper class, like so:
code :
public static class SplitHelpers 
{
   public static readonly char[] Comma = { ',' };
   public static readonly char[] Stuff = { ',', ':', ';' };
   // etc.
}
myString.Split(SplitHelpers.Stuff, StringSplitOptions.RemoveEmptyEntries)

wish helps you The optimized version is more than fair to std::function.
std::function typical implementation is a type erased pImpl inner class that has a virtual invocation and copy interface.

I wish did fix the issue. I consider myself a newbie. So I have one question for you. , What you actually want is
code :
_.remove($scope.lineLeagues, function(lineLeague) {
  return lineLeague == league;
});
_.pull($scope.lineLeagues, league)

seems to work fine There will be a performance gain primarily because there is no longer any memory allocation overhead, and you save tons of space. But the more important part is that you're colorizing the same array in the second code example, whereas in the first one you are colorizing a different array every time. If this is what you want, great! If not, then you need to rethink your code.

Does that help The cost of creating the context is very low. However, using a new context means that you don't have any cached queries from previous contexts. You can work around this to some degree with view generation or CompiledQuery. See also Performance Considerations for Entity Framework Applications
On the other hand, keeping a context around for a long time means you are tracking increasing amounts of state information, which has a performance cost of its own.
