Ruby : How to get thrift type of attribute ?

[Alexis Gryta <al...@crisalid.com>]

Hi everybody !

I would like to process many attributes automatically.
But my data are read from a file and they are string type...
I would like to know if there is a solution to know the type of attribute.
Thanks to this, I'll be able to convert string into the right type.

struct Test{
1: i32 id,
2: string name,
3: Enumeration genre
}

test = Test.new
A method which does (for example) :
puts test.id.type  => Give me i32
puts test.string.type  => Give me string
Etc..

I can use test.id.class but it doesn't work .. (tell me nilClass when it
isn't assigned)
And even if "id" is a i32,
test.id = "blabla"  => works... (normally, it shouldn't)
The verification of type is done only when you try to serialize... not when
you assign a value into a thrift object.

Thank you !

I assumed I was going to find an answer by Jens at SO, but since I didn't I
took a stab at it
http://stackoverflow.com/a/24066653/652904

probably not the most accurate, but what I have at the moment
