Applying custom effects to Program's loaded within a custom FileSystem

[nmggithub]

I am helping in developing the GhidraApple Ghidra extension. I am working on a custom FileSystem for the DYLD cache that can then apply custom effects to any loaded Program's. More specifically, I would like to pass data from the FileSystem class into a format that can then be read by a custom Loader.

It is unclear to me how I can do this. My first approach was to create a custom ByteProvider with fields for the data. However, it appears that all ByteProvider's are wrapped in a RefdByteProvider before being passed to the Loader layer, and the getWrappedByteProvider method is not public.

I know the idea of using ByteProvider was a bit hack-y. Is there a better way to move data across from the FileSystem layer to the Loader layer?

OK, I think I found out a solution. Using the FileSystemService, I can get the instance of my custom FileSystem. I would just need to store member variables in that instance and access them. It's still a bit hack-y, but it is more straightforward than my previous attempt.

This issue #7355 sounds pretty close to what you are describing and discusses the issues.

Thanks for the note! I'll take a look at that as well.
