[julia-users] Composite type fields and types defined

2014-03-01 Thread Ben Ward 


Hi,

Is there a way to extract the names and types of the fields in a given 
composite type? 

Say:

type MyType
 a::Int
end

Is there a way to get the field 'a', and the type of the field Int? I think 
I've seen a way to get the type in the manual but not the name assigned to 
the field.

And also how do I list all the types defined in a module? I'm planning on 
attempting to use Julia's metaprogramming features for a task where I need 
to know these things.

Thanks,
Ben.

 have a look at

 This works 
 MyType.names 
 MyType.types 

 there is also the names function.  Don't know if there is a 
 corresponding 'types' function.  Incidentally names also list all names 
 defined in a module.
