Android Question Step through "Type" variables?

[TheMightySwe]

Is there any way to step through a "Type" like the one below in some kind of loop?

Type SQLTypes (BlobType As Int, DateTimeType As Int, StringType As Int, DoubleType As Int, IntType As Int, BooleanType As Int)

Do you want to go over all the fields? Create a sub that receives this type and returns a Map with the fields names as keys and the values.

So how do I do that convertion from the type to the map?

You'll have to do it manually, field by field.

Sub SQLTypesToMap (t As SQLTypes) As Map
 Return CreateMap("Blobtype": t.Blobtype, "DateTimeType": t.DateTimeType, ...)
End Sub

OK, oh my!

That might work, but with a huge problem.

My Type has almost a thousand Integers and changes alot when new functions are added. Is there any way to step through it to get the Variable names?

If not, i just do it the hard way.

Why do you need to go over all the fields? If you want to serialize the type instances then there are simpler ways to do it.

I want to use the Names from the type instances for a map that saves if a user has or hasn't access to the function that corresponds with the type instance.

Maybe you should take a step back and reconsider using a type and think about using some other construct instead? Class, map, array, list, database are all viable alternatives, depending a bit on your specific needs.

Use KeyValueStore (or RandomAccessFile.WriteB4XObject). It allows you to save a type instance or any collection that holds other types in a single line of code.

The thing is i can't change this because its embedded in thousands of places in a huge project, if it's not possible to get the variables names out, I will fix another solution ofcourse. But it does not hurt to ask.

I don't know the project, but, in my experience, don't underestimate the power of search and replace, and simple find and manual correct.

I'd make a copy of the project, and then start doing the change, just to get a feel for how big it really is. Usually, when I fear a big rewrite, it's much less work than I thought.
