naming

问题 I have a problem, where I have two third party libraries classes that I have to extend and use together. But both have the same naming convention and two class name end up having the same name. Since I cannot extend two classes, I don't know how to fix them, how to create a wrapper against one. I cannot use PHP Namespaces as the PHP version is just 5.2.10 and not 5.3. What options I have? 回答1: I think you can implement rpc like interface, for one class. For other you can extend and use. http:

问题 I noticed that in many community Objective-C classes and in Apple's frameworks they name some of the variables using a convention that prefixes variables with an underscore, such as: _name . What is the reason for having the underscore. Should I be doing this in my own classes? If so where and when should I use it? 回答1: In Cocoa, it's a convention to indicate the something is private and shouldn't be used externally. However, it's unofficial convention, particularly in light of wording like

问题 Ok question title is far from being self-explanatory. I see myself doing this often: From this answer: public static class Equality<T> { public static IEqualityComparer<T> CreateComparer<K>(Func<T, K> keySelector) { return new KeyEqualityComparer<K>(keySelector); } class KeyEqualityComparer<K> : IEqualityComparer<T> { readonly Func<T, K> keySelector; public KeyEqualityComparer(Func<T, K> keySelector) { this.keySelector = keySelector; } public bool Equals(T x, T y) { ---- } public int

问题 Some of naming is described here: http://www.weston-fl.com/blog/?p=840/ However, I want to check this from official manual. Where can I find this info from official manual? 回答1: The official Apple document is Technical Q&A QA1686 “App Icons on iPad and iPhone”. 来源： https://stackoverflow.com/questions/9356874/where-can-i-find-informations-about-ios-image-file-naming-in-official-manual

问题 In my program i'm currently working on programmatically adding a variety of form objects in C#. For example i'm trying to create a certain group of panels, which contain the data I wish to show. When loading the form I have a file which contains all of the data I wish to load in, the loading itself works fine but when loading I need to create a variety of form labels, panels and images to display all of the necessary data and as such I need to make these panels and labels all with a seperate

问题 I have a list of files say... T123_Product_1.jpg T123_Product_2.jpg T123_Product_3.jpg T456_Product_1.jpg T456_Product_2.jpg T456_Product_3.jpg etc. etc. etc. for about 900 more files What I am needing to do is create a folder based on the characters before the first underscore, but to not repeat it since there are multiple files. So in the example above, I would only want two folders named T123 and T456. Then I would need the script to place the appropriate files in the folder. I had found

问题 In tutorials I have seen two types of instance attribute naming for the purpose of using @property. Here is code showing examples of both. They also seem to work differently. class A: def __init__(self, x): self.x = x @property def x(self): return self.__x @x.setter def x(self, x): if x > 1000: self.__x = 1000 else: self.__x = x # Instance attribute __x defined outside __init__ class B: def __init__(self, x): self._x = x @property def x(self): return self._x @x.setter def x(self, x): if x >

问题 I'm writing a Range class at the moment and I'm looking for a good name for the common range [0->1]. If it was a vector of length 1, I would call it a Unit vector. Is there a clear name to give this range/interval? Possibly a Unit Range ? 回答1: The closed range between [0,1] is typically called the closed unit interval. If you do not include the endpoints it would be the open unit interval. 回答2: I would go for Interval, as it sounds better than 'Unit Range' :) 回答3: How about Normal Range ? 来源：
