  • What is the most efficient approach to fetch category tree, products, brands, counts by subcategory

    - by alex227
    Symfony 1.4 + Doctrine 1.2. What is the best way to minimize the number of queries to retrieve products, subcategories of current category, product counts by subcategory and brand for the result set of the query below? Categories are a nested set. Here is my query: $q = Doctrine_Query::create() ->select('c.*, p.product,p.price, b.brand') ->from('Category c') ->leftJoin('c.Product p') ->leftJoin('p.Brand b') ->where ('c.root_id = ?', $this->category->getRootId()) ->andWhere('c.lft >= ?', $this->category->getLft()) ->andWhere('c.rgt <= ?', $this->category->getRgt()) ->setHydrationMode(Doctrine_Core::HYDRATE_ARRAY); $treeObject = Doctrine::getTable('Category')->getTree(); $treeObject->setBaseQuery($q); $this->treeObject = $treeObject; $treeObject->resetBaseQuery(); $this->products = $q->execute();

  • Using enum values to represent binary operators (or functions)

    - by Bears will eat you
    I'm looking for an elegant way to use values in a Java enum to represent operations or functions. My guess is, since this is Java, there just isn't going to be a nice way to do it, but here goes anyway. My enum looks something like this: public enum Operator { LT, LTEQ, EQEQ, GT, GTEQ, NEQ; ... } where LT means < (less than), LTEQ means <= (less than or equal to), etc - you get the idea. Now I want to actually use these enum values to apply an operator. I know I could do this just using a whole bunch of if-statements, but that's the ugly, OO way, e.g.: int a = ..., b = ...; Operator foo = ...; // one of the enum values if (foo == Operator.LT) { return a < b; } else if (foo == Operator.LTEQ) { return a <= b; } else if ... // etc What I'd like to be able to do is cut out this structure and use some sort of first-class function or even polymorphism, but I'm not really sure how. Something like: int a = ..., b = ...; Operator foo = ...; return foo.apply(a, b); or even int a = ..., b = ...; Operator foo = ...; return a foo.convertToOperator() b; But as far as I've seen, I don't think it's possible to return an operator or function (at least, not without using some 3rd-party library). Any suggestions?

  • How to interpret binary data as an integer?

    - by StackedCrooked
    The codebase at work contains some code that looks roughly like this: #define DATA_LENGTH 64 u_int32 SmartKey::SerialNumber() { unsigned char data[DATA_LENGTH]; // ... initialized data buffer return *(u_int32*)data; } This code works correctly, but GCC gives the following warning: warning: dereferencing pointer ‘serialNumber’ does break strict-aliasing rules Can someone explain this warning? Is this code potentially dangerous? How can it be improved?
