getter

问题 Simple piece of code about dataTable . CentralFeed is SessionScoped Bean, and PostComment is RequestScoped Bean <h:form id="table"> <h:dataTable value="#{CentralFeed.profileComments}" var="item"> <h:column> <h:outputText value="#{item.comment}"/><br/> <h:inputTextarea value="#{item.newComment}" rows="2"/><br/> <h:commandButton value="Post" action="#{PostComment.postReply(item)}" /> </h:column> </h:dataTable> </h:form> inside CentralFeed.java private List<NewsFeed> profileComments = null;

问题 I have a mocked object that is passed as a constructor argument to another object. How can I test that a mocked object's property has been called? This is code I am using currently: INewContactAttributes newContact = MockRepository.GenerateMock<INewContactAttributes>(); newContact.Stub(x => x.Forenames).Return("One Two Three"); someobject.ConsumeContact(newContact); newContact.AssertWasCalled(x => { var dummy = x.Forenames; }); This works except when within the "someobject" the getter on

问题 I was reading this article on why getter and setters are evil. The article doesn't say not to use them ever, but, it's telling you to think in a way that limits the use of those methods, or to quote the article: Don't ask for the information you need to do the work; ask the object that has the information to do the work for you. what happens when you need to display data in a GUI, but don't have getter methods? The article covers this briefly, but not fully. It mentions passing a JComponent

问题 I've a list of strings, field names, of a class in a loop from resource bundle. I create an object and then using loop i want to set values for that object. For example, for object Foo f = new Foo(); with parameter param1, I have string "param1" and I somehow want to concate "set" with it like "set"+"param1" and then apply it on f instance as: f.setparam1("value"); and same for getter. I know reflection will help but I couldn't manage to do it. Please help. Thanks! 回答1: You can do something

问题 What is the best practice for a C++ getter method which is supposed to return a non trivial type, but a member which is of type class, or struct. Return by value, such as: MyType MyClass::getMyType() { return mMyType; } Return by const reference: const MyType& MyClass::getMyType() { return mMyType; } Return by address: MyType* MyClass::getMyType() { return &mMyType; } where class MyType { /* ... */ }; class MyClass { private: MyType mMyType; } I specifically worry about the following usages

问题 I would like to know a good syntax for C++ getters and setters. private: YourClass *pMember; the setter is easy I guess: void Member(YourClass *value){ this->pMember = value; // forget about deleting etc } and the getter? should I use references or const pointers? example: YourClass &Member(){ return *this->pMember; } or YourClass *Member() const{ return this->member; } whats the difference between them? Thanks, Joe EDIT: sorry, I will edit my question... I know about references and pointers,

问题 I am familiar with Java, but just starting to learn JavaFX, and specifically learn about JavaFX properties. I understand the basic design pattern as shown in the following example from Oracle: package propertydemo; import javafx.beans.property.DoubleProperty; import javafx.beans.property.SimpleDoubleProperty; class Bill { // Define a variable to store the property private DoubleProperty amountDue = new SimpleDoubleProperty(); // Define a getter for the property's value public final double

问题 Several questions about accessor methods in C++ have been asked on SO, but none was able satisfy my curiosity on the issue. I try to avoid accessors whenever possible, because, like Stroustrup and other famous programmers, I consider a class with many of them a sign of bad OO. In C++, I can in most cases add more responsibility to a class or use the friend keyword to avoid them. Yet in some cases, you really need access to specific class members. There are several possibilities: 1. Don't use
