How to extend static methods for enums implementing an interface?

我的未来我决定 提交于 2019-12-11 07:17:32
问题 This question is closely related to my previous question on SO about using interface with enums. Essentially, I have a bunch of enums that are closely related, and they all implement a common interface. The interface is called Sections and the enums are called SectionA , SectionB , etc. I have other classes which have fields like List<Sections> and Map<Sections, String> . Now, to populate these fields, I would like to have access to valueOf(String) , i.e. I would like to be able to say

AspectJ pointcut on method in Spring CrudRepository

问题 I'm using Spring's CrudRepository in combination with the annotation @RepositoryRestResource to implement a simple CRUD-app that can be used throught a RESTful API. I now want to add an AspectJ pointcut on my repository , so that some functionalities will be executed whenever a CRUD-method from the interface is called. First, I extend Spring's CrudRepository to add some custom functionalities in my own interface: @RepositoryRestResource(collectionResourceRel = "customers", path = "customers")

问题 I am coding a mini-project of sorts about medical information, and in it, I am reading text from several data sources. All these text sources have the same type of information, but under slightly different labels. For example, sourceA has a section titled "adverse effects" while sourceB calls it "side effects". I have an interface called Reader , and several classes ( AReader , BReader , etc.) implementing this interface. Also, I have enum for each class for the section titles. For example:

Changing property stubs for Interface refactoring

拥有回忆 提交于 2019-12-11 06:50:01
问题 Is it possible to change the stub used to implement interfaces in Visual Studio 2008? For instance, when I choose either Implement interface 'IMyInterface' or Explicitly implement interface 'IMyInterface' Instead of a number of properties that look like this: public string Comment { get { throw new NotImplementedException(); } set { throw new NotImplementedException(); } } I'd like my properties to use the C# 3.0 auto-implemented properties and look like this: public string Comment {get;set;}

问题 At this moment I start work on small web application based on MVC. Now I try implement main classes for Model layout using DAO pattern. So, first of all I create two entity classes (for example): Author and Book: package myProject.model.entity; import java.io.Serializable; public class Author implements Serializable { private static final long serialVersionUID = 7177014660621405534L; private long id; private String firstName; private String lastName; public Author() { } // getter and setter

Delphi Interfaces and DLL's

|▌冷眼眸甩不掉的悲伤 提交于 2019-12-11 06:26:21
问题 I'm trying to figure out a safe way of passing objects from a main app to a DLL (for a plugin system). The idea is to use the main app's TZConnection (database access from Zeos Lib) in the dll's. I'd rather not use Runtime Packages, and DLL must be the way to go (I don't need BPL's need to recompile each time, and have no idea of how to use COM). I've been told it's possible to do it with Interfaces. I've never used them before, but been messing around with it, and managed to do it... But, I

Get multiple network interface gateway address in linux

问题 There are many ways to get the network interfaces IP adresses in GNU/Linux (for example with ioctl calls). And also, default gateway from the routing table is available in C. But I have 2 network interfaces in 2 different networks. Each of these have unique router IP addresses (gateway addresses). How can I get these addresses? The DHCP offers tells them as well and I'm able to get them with nmcli device list for example. But where is this information stored? The NetworkManager database? I

Fragment to Activity Communications

问题 I will come clean immediately by admitting that I don't understand Interfaces. I believe that I followed the process laid out in https://developer.android.com/training/basics/fragments/communicating.html. In section Define an Interface, I declare and define the required interface NewDate: public class DatePickerFragment extends DialogFragment { NewDate mCallback; private static final String TAG = "DatePickerFragment"; public Date date; private DatePicker mDatePicker; //interface implemented

问题 I am testing this simple arduino code in python but it works in arduino serial not in python. User defines the number of blinks on the led. This works on arduino serial monitor. But when I use it in python it does not work. can anyone help? Thank you Arduino code: int ledPin = 13; // select the pin for the LED int val = 0; // variable to store the data from the serial port void setup() { pinMode(ledPin,OUTPUT); // declare the LED's pin as output Serial.begin(9600); while (!Serial) { ; // wait
