lookup

问题 I have a question related with possible performance issue while using @EJB annotation. Imagine following scenario public class MyBean1 implements MyBean1Remote{ @EJB private MyBean2Remote myBean2; @EJB private MyBean2Remote myBean3; ... @EJB private MyBean20Remote myBean20; } There is a bean with many dependencies to other beans. According to EJB spec if I would like to inject MyBean1Remote to some other bean, container would have to take all required dependencies from its pool inject it into

问题 I have an excel formula, which is supposed to work but returns #VALUE and I cannot figure out why. I have this table: A B 1 | | | 2 | Oranges | 1 | 3 | Apples | 2 | 4 | Grapes | 3 | 5 | Oranges | 4 | 6 | Apples | 5 | 7 | Grapes | 6 | 8 | Apples | 7 | I want to Check for matching values in Column A like "Apples", "Oranges", etc. and return all the corresponding values from Column B in one row: The output should be like this but I only get #VALUE: A B C D 11 | Apples | 2 | 5 | 7 | 12 | Oranges

问题 I am working on a custom data structure and I am currently in the beta testing process: The data will be stored within an array and this array can be represented as a 4D, 2D & 1D array. These three arrays are declared within a union since it represents the same memory addressing. Here is the declaration to my class: SomeClass.h #ifndef SomeClass_H #define SomeClass_H class SomeClass { public: static const unsigned V1D_SIZE; // Single Or Linear Array Representation : Size 256 - 256 Elements

问题 Extending this question, I have accepted an answer which says use lookup table or hashmap for this case as it would be a better construct to handle multiple conditions . Current construct. Class to store messages. public class ProgressMessages { public static String msg1="Welcome here ....."; . . . //around 100 more similar static variables. } Condition and Display the proper message from the above class. int x=calculatedVal1(m,n); int y=calculatedVal2(o,q); SimpleDateFormat formater=new

问题 I have a query, that use $lookup to "join" two models, after this i use $project to select olny the fields that i need, but my $project brings an arrray of objects ( user_detail ) that contains more data that i need. I want only two fields ( scheduleStart and scheduleEnd ) of my result. My query: User.aggregate([{ $match: { storeKey: req.body.store, } }, { $group: { _id: { id: "$_id", name: "$name", cpf: "$cpf", phone: "$phone", email: "$email", birthday: "$birthday", lastName: "$lastname" },

问题 How should this code behave? It calls generic function ignoring my overload if I use qualified name in call_read() function; and it calls overload first and then generic version if I use unqualified name. What's the difference? Is it a bug in GCC? #include <iostream> struct info1 {}; struct info2 {}; template<class T> void read(T& x) { std::cout << "generic" << std::endl; } template<class T> void call_read(T& x) { ::read(x); // if I replace ::read(x) with read(x) the overload is called } void

问题 I have a variable of type Dictionary<MyType, List<MyOtherType>> I want to convert it to a Lookup<MyType, MyOtehrType> . I wanted to use Lambda functions to first, flatten the dictionary and then convert this to Lookup using the ToLookup() . I got stuck with the dictionary. I thought about using SelectMany but can't get it working. Anyone has got an idea how to do it? 回答1: How about: var lookup = dictionary.SelectMany(pair => pair.Value, (pair, Value) => new { pair.Key, Value }) .ToLookup(pair

问题 I have a VBA function that I would like to pass a custom range of data (As opposed to a full table column range) only when certain criteria within that table is met. For example: Table_1 Table_2 A B C A B 1 Policy Data Status | 1 Policy Function -------------------------- | ------------------- 2 AA 25 approved | 2 AA [25, 35] 3 AA 19 unapproved | 3 BB [16] 4 BB 16 approved | 5 CC 27 approved | 6 CC 30 unapproved | 7 AA 35 approved In Table2, cell B2, I would like to return a range of all Data
