kandi X-RAY | methods Summary
This gem aims at making referencing methods in the Ruby language easier. It is greatly inspired by this issue on the Ruby bug tracker. It allows you to grab a reference to a method by simply calling method on an object and calling the method you want on the result. It allows parameters currying and respects method's visibility.

QUESTION
I'm trying to remove an entry from the Caffeine cache manually. I have two attempts but I suspect that there are some problems with both of them:
This one seems like it could suffer from a race condition.
...ANSWER
Answered 2021-Jun-16 at 00:25You should use cache.asMap().remove(key)
as you suspected. The other call delegates to this, but does not return the value because that is not idiomatic for a cache.
The Cache
interface is opinionated for how one should commonly use a cache, while the asMap()
view is more raw to allow for advanced operations. For example, you generally wouldn't iterate over a cache (e.g. memcached doesn't allow this), but if you need to then the Map provides that support. All calls flow into the same backing structure, so there will be no inconsistency. The APIs merely try to nudge users towards best practices, but strive to not block a developer from getting their work done safely and correctly.
QUESTION
Context
Since Windows 10 version 2004 update, the Magnifier windows application was updated. And as with every update, there are some issues with it.
Since those issues might take a long time to fix, I've decided to implement my own small project full screen magnifier.
I've been developing in c#, .Net 4.6 using the Magnification API from windows magnification.dll . All went good and well, and the main functionality is now implemented. One thing is missing though, a smoothing Mode for pixelated content... Windows Magnifier implements an anti aliasing/ smoothing to the Zoomed in content.
I've checked and the Magnification API, doesn't seem to provide that option.
how do i add smoothing mode to magnifier on windows magnification API?
I'm aware of pixel smoothing methods, but not familiar with win32 API to know where to hook the smoothing method to, before the screen refreshes.
EDIT:
Thanks to @IInspectable answer, after a small search i found this call to the Magnification API in a python project.
Based on that, I wrote this snippet in my C# application , and it works as intended!
...ANSWER
Answered 2021-Jun-15 at 17:03There is no public interface in the Magnification API that allows clients to apply filtering (other than color transforms). This used to be possible, but the MagSetImageScalingCallback API was deprecated in Windows 7:
This function works only when Desktop Window Manager (DWM) is off.
Even if it is still available, it will no longer work as designed. From Desktop Window Manager is always on:
In Windows 8, Desktop Window Manager (DWM) is always ON and cannot be disabled by end users and apps.
With that, you're pretty much out of luck trying to replicate the results of the Magnifier application's upscaler using the Magnification API.
The Magnifier application appears to be using undocumented API calls to accomplish the upscaling effects. Running dumpbin /IMPORTS magnify.exe | findstr "Mag"
lists some of the public APIs, as well as the following:
MagSetLensUseBitmapSmoothing
MagSetFullscreenUseBitmapSmoothing
Unless you are willing to reverse-engineer those API calls, you're going to have to spend your time on another project, or look into a different solution.
A note on the upscaling algorithm: If you look closely you'll notice that the upscaled image doesn't exhibit any of the artifacts associated with smoothing algorithms.
The image isn't blurred in any way. Instead, it shows sharp edges everywhere. I don't know what upscaling algorithm is at work here. Wikipedia's entry on Pixel-art scaling algorithms lists some that have very similar properties. It might well be one of those, or a modified version thereof.
QUESTION
My Question: What exactly does “compile-time” mean? I present my understanding below and where I am getting confused.
Compilation is the process that generates a single executable .exe file from the .vb file. There are several ways to do this, for example by using the VBC.EXE command from the developer command window or MSDOS. The way I understand “compile-time” is that it is time when such a command gets executed and the exe file is generated. The following are the what I find confusing:
- When I write Dim i = 5, the compiler infers or “knows” that the variable “i” is an integer.
- If I want to print an integer or a string using the Writeline method of the console class then the compiler automatically determines which overloaded version it should call. So in this case also the compiler “knows” – this is also known as compile-time polymorphism.
My confusion: Since in both the above cases the compiler infers or knows the type of variable or the version of the overloaded method to call just after we have finished typing the sentence, is this also called compile-time? We have not given any sort of compilation command here.
- Another confusion on the definition of compile-time refers to the case when we explicitly define overloaded methods. In the case of the writeline method, we know from the pop-up given by intellisense that immediately after we have finished typing the sentence the version with the correct signature is called. Now, when we define overloaded methods does the compiler know which version to call when we call the function (depending on signature) somewhere in the program right after we have finished typing the code? Or does the compiler know this after the exe file has been generated? This is a case of compile-time polymorphism. But then which time or which step is the “compile-time”?
ANSWER
Answered 2021-Jun-15 at 19:35We have not given any sort of compilation command here.
No, but most modern IDEs can do similar "static analysis" that compilers do to determine types, etc. Some even do a very lightweight "compile" to determine what overloads are appropriate, etc.
Also note that IDEs and the actual compiler may not always agree. IDE analysis is designed to be very fast, so the analysis done by the IDE may be less robust and less accurate than a static compiler.
So in a sense these are all "compile-time" in that the only information that is available is what is present in the code. This is opposed to "run-time" where other factors such as user input, environment, and state can change the flow and interpretation of the program in ways that the compiler could not account for.
QUESTION
I want to collect the names (Jenny, Tiffany, etc.) that are stored in every object. and these objects live in an array. I've used Array.prototype.every()
and Array.prototype.forEach()
, but I don't think they are the right methods.
I also want to note that majority of these codes are from Codaffection. I am practicing on developing in React.
If you would like to experiment with the code, click here.
In every object, there is an id, fullname, email and etc.
This is the code that adds, edits, generates unique ids for each employee, and gets all storage data.

QUESTION
First time actually using anything to do with swing - sorry for the poor code and crude visuals!
Using swing for a massively over-complicated password checker school project, and when I came to loading in a JMenuBar, it doesn't render properly the first time. Once I run through one of the options first, it reloads correctly, but the first time it comes out like this:
First render attempt
But after I run one of the methods, either by clicking one of the buttons that I added to check if it was just the JFrame that was broken or using one of the broken menu options, it reloads correctly, but has a little grey bar above where the JMenuBar actually renders: Post-method render
The code for the visuals is as follows:

I am currently working on the Selenium Nunit Testing using C# with VS code.
We are following page object model.
We just wanted to list down all the methods and class in a document or web page (localhost) like how api document look like ..
How to achieve this?
Thanks
...ANSWER
Answered 2021-Jun-15 at 15:22To be clear, you are looking for some way to document all the classes/methods that make up your page object model?
That doesn't have anything to do with selenium or nunit. Just document your C# code with XML documentation comments like this:
