问题 I have an address object that I want to create an equals method for. I could have made this quite simple by doing something like the following (shortened a bit): public boolean equals(Object obj) { if (this == obj) return true; if (obj == null) return false; if (getClass() != obj.getClass()) return false; Address other = (Address) obj; return this.getStreet().equals(other.getStreet()) && this.getStreetNumber().equals(other.getStreetNumber()) && this.getStreetLetter().equals(other

问题 I have code that looks like this: itemView.Question.AnswersJSON = itemView.Answer.ToJSONString(); itemView.Question.Modified = DateTime.Now; itemView.Question.ModifiedBy = User.Identity.Name plus many more lines where I set values for the Question class that is inside the itemView . I think the answer is "not possible" but just putting it out as a question in case anyone knows a way. What I would like to do is to find a way to simplify this code without repeating itemView.Question in every

问题 This was something originally discussed during a presentation given by Charles Brian Quinn of the Big Nerd Ranch at acts_as_conference. He was discussing what he had learned from instructing a Ruby on Rails Bootcamp to many people both new to programming and new to Rails. One particular slide that stood out was along the lines of never using foo and bar as examples when trying to teach someone to program . His reasoning was very simple. Which is easier to understand? baz = foo + bar or answer

Is there any tool similar to AStyle to format matlab code in m-files? 回答1: In recent versions of MATLAB, you can use the "Smart Indent

问题 Normally, when doing some work on an existing project, I would just go with whatever style is already established in the code base. But our team has to maintain multiple small to medium sized projects which all differ slightly in coding style. It would be more efficient and less confusing if we could cleanup these differences. So I'm looking for a tool that allows me to refactor the existing style. Lots of features are already provided by standard code formatting tools, like changing the

I know that white space is irrelevant in JavaScript, but I am curious about style. When defining a function like: function Foo(a, b, c

问题 I would like to know if it is acceptable/preferred to use self::method() and parent::method() when working in php classes. You can use $this->method() but $this-> can also refer to a class variable, a parent class variable, or a method from the parent class. There is no ambiguity in self:: Is self:: depreciated and/or are there any caveats or cons to using this style? I understand that self:: and parent:: refer to a static instance of the class, but in kohana, unless you specifically define a

问题 Is there a best practice for making private methods in classes static? I have a class with a few methods. Some of these can easily be made static, since they simply process data. Should I make them static or just leave them as is? Is this more of a style issue? Are there performance considerations? Edit: Method can be made static, but should it? 回答1: If the methods don't access any of the type's state then they should be static. Static method calls provide a performance gain over instance

问题 Typically you will find STL code like this: for (SomeClass::SomeContainer::iterator Iter = m_SomeMemberContainerVar.begin(); Iter != m_SomeMemberContainerVar.end(); ++Iter) { } But we actually have the recommendation to write it like this: SomeClass::SomeContainer::iterator Iter = m_SomeMemberContainerVar.begin(); SomeClass::SomeContainer::iterator IterEnd = m_SomeMemberContainerVar.end(); for (; Iter != IterEnd; ++Iter) { } If you're worried about scoping, add enclosing braces: { SomeClass:
