I have already searched in the shortcuts in the Xcode preferences but I couldn't find a way to get it back. My current interface: Click the "square in a circle" button at the top, left of the "show standard editor" button. Alternatively, use "View > Libraries > Show Library" or hit Shift-Cmd-L. 来源: https://stackoverflow.com/questions/52566356/my-library-pane-is-missing-how-to-get-it-back

Utility classes.. Good or Bad?

狂风中的少年 提交于 2019-11-28 21:33:52
问题 I have been reading that creating dependencies by using static classes/singletons in code, is bad form, and creates problems ie. tight coupling, and unit testing. I have a situation where I have a group of url parsing methods that have no state associated with them, and perform operations using only the input arguments of the method. I am sure you are familiar with this kind of method. In the past I would have proceeded to create a class and add these methods and call them directly from my

How can I create an utility class? [duplicate]

This question already has an answer here: Java: Static Class? 7 answers I want to create a class with utility methods, for example public class Util { public static void f (int i) {...} public static int g (int i, int j) {...} } Which is the best method to create an utility class? Should I use a private constructor? Should I make the utility class for abstract class? Should I do nothing? initramfs For a completely stateless utility class in Java, I suggest the class be declared public and final , and have a private constructor to prevent instantiation. The final keyword prevents sub-classing

Good tool for testing socket connections? [closed]

我与影子孤独终老i 提交于 2019-11-28 15:43:06
I'm writing a tcp/ip client and I would need a "test server" to be able to test easily. It should listen on a configurable port, show me when a client connects and what the client sent, allow me to manually enter text to send to the client. It should work on Windows. Normally I would have use the simple but powerfull nc.exe (alias "Netcat" available as well on Unix as on Windows) but the antivirus detects it as an "hacker tool" so that my system administrator doesn't want me to use it at work. Does anyone use another tool to test socket connections and is happy with it? Hercules is fantastic.

Minimizing jar dependency sizes

痴心易碎 提交于 2019-11-28 09:58:06
an application I have written uses several third party jars. Sometimes only a small portion of the entire 50kB to 1.7mB jar is used - one or two function calls or classes. What is the best way to reduce the jar sizes. Should I download the sources and build a jar with just the classes I need? What existing tools can help automate this (ex I briefly looked at http://code.google.com/p/jarjar/ )? Thank you Edit 1: I would like to lower the size of my third party 'official' jars like swingx-1.6.jar (1.4 MB), set-3.6 (1.7 MB) glazedlists-1.8.jar (820kB) , etc. so that they only contain the bare

How can I programmatically manipulate Windows desktop icon locations?

|▌冷眼眸甩不掉的悲伤 提交于 2019-11-28 07:23:30
Several years back, I innocently tried to write a little app to save my tactically placed desktop icons because I was sick of dragging them back to their locations when some event reset them. I gave up after buring WAY too much time having failed to find a way to query, much less save and reset, my icons' desktop position. Anyone know where Windows persists this info and if there's an API to set them? Thanks, Richard If I'm not mistaken the desktop is just a ListView, and you'll have to send the LVM_SETITEMPOSITION message to the handle of the desktop. I googled a bit for some c# code and

Iphone SDK Utility Application template has leak

大憨熊 提交于 2019-11-27 23:38:15
i'm only create an project with a Utility Application template. This template has a native memory leak when i push "info button" to flip the view. Anyone know how can i fix this leak ??? I just make an new project from this template, i don't add new objects. That might be a leak or it might not be a leak. If you were to add the backtrace of the allocation, that would be helpful. More likely than not, it isn't a leak, but some bookkeeping information that is being stashed away by dyld that leaks/Instruments loses track of. Given that it is 128 bytes and I'm guessing there is only one of them, I

Is it possible to have a transparent utility stage in javafx? [duplicate]

梦想的初衷 提交于 2019-11-27 15:24:26
This question already has an answer here: A javaFX Stage could be both StageStyle.UTILITY and StageStyle.TRANSPARENT? 5 answers I know that you can set a stage to have a utility style "Stage.InitStyle(StageStyle.UTILITY);" and you can set it to have a transparent style "Stage.InitStyle(StageStyle.TRANSPARENT);" but can you have both in the same stage? I am tiring to make it so that the stage does not show as a window down in the start menu and I would like the stage to be invisible so that you can only see the scene. You can always do it the old way using Swing where that feature was available

Java Utility Class vs. Service [closed]

人盡茶涼 提交于 2019-11-27 11:54:50
What's the difference in Java between a utility class (a class with static methods) and a Service class (a class with public methods that provides a "service"). For example, one can argue that a cryptographic object (providing methods to encrypt, decrypt, hash or get a salt value) is a Service provider, but many group this functionality into a Utility class with static methods, like CryptoUtil.encrypt(...). I'm trying to figure out which way follows better "design". Thoughts? Different behaviors can be obtained by using different service objects. Static methods in a utility class can't be
