How to access files inside a package or a class folder?

Hello,

I have the organized my classes in a package as follows: * ./+myPck/@myClassA/myClassA.m * ./+myPck/@myClassB/myClassB.m

In the methods of myClassB, I need to:

• read file.txt, a file provided with the package and not meant to be changed
• read and modify var.txt, a file provided as default by the package, but which can be modified by the methods of myClassB
• the default var.txt should be kept unmodified for new instances of myClassB.

How can I do that properly? The end user should not see file.txt and var.txt in his current folder, it should be kept hidden from him.

Therefore, 2 questions:

• Is it possible to have for instance a folder ./+myPck/src with all read only files that I need? How can I access them, given that ./+myPck is not my current folder, potentially also not a subfolder from the current folder.
• How can I write new files that still stay hidden (that is, which are not in the current folder) from the end user? I could maybe write them inside the +myPck folder, but I don't know if it's a good practice to pollute the +myPck folder with generated file, especially in the case the package folder is transmitted to other user... A potential solution I've thought of: a +myPck/tmp folder where files are written in, which could be emptied when the object is deleted. However I think this solution is not very "best practice", and doesn't work when 2 instances of myClassB are created, but only 1 deleted: the files of the second one in the tmp folder are also deleted...

I couldn't find help about this problem in the doc. I would be very glad for any advice. Thank you.

Jo.

Hi Jo,

did you find a solution to this problem? I am facing a similar case in which I want to contain source files directly within the classpath that the class is supposed to access when loading default properties, e.g., a text file, or an image, etc.

It would be great to get an answer about this.
