问题 I want to sort a vector of date s and I wrote compare function for it: #include <iostream> struct date { int day; int month; int year; }; int compare_dates(date a, date b) { if (a.year < b.year) { return -1; } else if (a.year == b.year) { if (a.month < b.month) { return -1; } else if (a.month == b.month) { if (a.day < b.day) { return -1; } else if (a.day > b.day) { return 1; } } else { return 1; } } else { return 1; } return 0; } int main() { date a = {}; date a.day = 19; date a.month = 11;

问题 I have an ObservableList of custom objects RecipeObject_Fermentable , whose properties I am displaying to the user through a TableView . For the most part it works well; when I populate the ObservableList with a new item, the TableView displays its contents. Using the .setCellValueFactory() method for each column allows me to display the simple objects (Strings and Doubles) as text in my TableView very easily. For instance, I can access property ' name ' of type String with... private

问题 I know how to create relation: QBCustomObject customObject = new QBCustomObject("Comment"); // your Class name customObject.put(fieldHealth, 99); customObject.put("text", "The first film in the series was..."); customObject.setParentId("50aa4d8fefa357fa14000001"); QBCustomObjects.createObject(qbCustomObject, new QBCallbackImpl() { @Override public void onComplete(Result result) { if (result.isSuccess()) { QBCustomObjectResult qbCustomObjectResult = (QBCustomObjectResult) result;

问题 In my app I fetch a coredatabase and put results into an array called self.stores. I convert those store locations to MyLocation objects which have a distance property. I plot the MyLocation objects like so: - (void)plotStorePositions:(NSString *)responseString { for (id<MKAnnotation> annotation in _mapView.annotations) { [_mapView removeAnnotation:annotation]; } //CYCLE THRU STORE OBJECTS for (Store * storeObject in self.stores) { NSString * latitude = storeObject.latitude; NSString *

问题 I've been searching if it is possible to get a JSON dictionary or array and directly map it in a custom object whose properties have the same name as the JSON tags, but I din't find any information regarding that. I've been parsing JSON dictionaries manually, like this: id deserializedObj = nil; id jsonObject = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingAllowFragments error:&error]; if ([jsonObject isKindOfClass:[NSDictionary class]]) { NSDictionary *jsonDictionary

How can we send custom object from outside to the Job Context. This Object changes from Job to Job and generated at runtime depending on Business case.

问题 I don't know if this could be done, but I have a WCF service that should return a custom object, the object has a collection of another custom object that contains a stream. when I try to return this object I get System.Runtime.Serialization.InvalidDataContractException: Type 'System.ServiceModel.Dispatcher.StreamFormatter+MessageBodyStream' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the

问题 I'm relatively new with using Google Maps API. Right now I am working on a project where a user can select various search filters and see results automatically show up on the map without reloading the page. My approach thus far has been to create a Javascript object with controls the map so that I could manipulate pieces of it as I wish (ie, centerMap(), addMarker(), clearMap(), etc). I developed several proof-of-concept pieces before beginning this phase of the project. Right now I am at the

问题 I have developed a small app that stores locally in iOS through archiving an array of custom objects containing: @property (nonatomic, copy) NSString *name; @property (nonatomic, copy) NSString *dateCreated; @property (nonatomic, copy) NSString *desc; @property (nonatomic, copy) NSString *url; I want to sync said archive using iCloud and I believe the recommended mechanism is through a UIDocument subclass. All UIDocument examples I found utlilized a single instance with 1 single NSString, so
