问题 I'm trying to store arrays (or vectors) of data in a SQLite database but I'm having problems trying to find a decent way to do so. I found some other post on StackOverflow, that I can't seem to find anymore, which mentioned storing the data in a table like the following: CREATE TABLE array_of_points ( id integer NOT NULL, position integer NOT NULL, x integer NOT NULL, y integer NOT NULL, PRIMARY KEY (id, position) ); So to store all the data for a single array you would insert each item under

问题 I have a class Type which cannot be copied nor it contains default constructor. I have second class A that acts as a set of the above classes. This second class gives access via iterators and my iterator has dereference operator: class A { class iterator { [...] public: Type & operator*() { return instance; } private: Type instance; } [...] }; Now to expose that I wrote a boost::python code that looks like that: class_<A>("A", [...]) .def("__iter__", iterator<A, return_internal_reference<> >(

问题 I know Java's constructors can't have any type and interestingly it cannot even be void . A logical explanation for that would be that a constructor returns the initialized object's reference. MyClass myObject = new MyClass(); The constructor of myClass will now return the object reference after instantiating it and save it in the object variable MyObject and that's why the constructor can't have a return type. Is that right? Could someone confirm this? 回答1: No, actually, the constructors are

问题 In the example code below I allocate some instances of the struct Chunk. In the for loops I then iterate through the memory block and access the different instances by using either pointer or references, and assign them some random data. But which for loop will execute the fastest? By my knowledge I'd say the reference-loop will be the fastest because it will require no dereferencing and has direct access to the instance in memory. How wrong / right am I? struct Chunk { unsigned int a; float

问题 I'm creating a GATE app which used to find co-reference text. It works fine and I have created zipped file of the app by export option provided in GATE. Now I'm trying to use the same in my Java code. Gate.runInSandbox(true); Gate.setGateHome(new File(gateHome)); Gate.setPluginsHome(new File(gateHome, "plugins")); Gate.init(); URL applicationURL = new URL("file:" + new Path(gateHome, "application.xgapp").toString()); application = (CorpusController) PersistenceManager.loadObjectFromUrl
