Re: [Vala] difference between using IntegerType and inheriting

2014-01-06 Thread Andre Masella 
Silly question: why do you want to be an integer?

Most atom types are not really integers at all. I mean, given Atom a and
Atom b, what does a+1 mean? a+b? max(a, b)? a * b? Usually, those answers
are non-sense. Most of the methods you would inherit from the base numeric
type are not helpful. You may just want:

[SimpleType]
[CCode (cname = "c_name", has_type_id = false)]
public struct StructName {
  public string to_string () { return ((uint32)this).to_string (); }
}

Re: [Vala] difference between using IntegerType and inheriting

2014-01-06 Thread rastersoft 
My question, really, is which one is the best to define in a VAPI file a 
typedef. This is: if I have in C


#typedef uint32_t xcb_atom_t;


is better to define it as:

[SimpleType]
[IntegerType (rank = 9)]
[CCode (cname = "xcb_atom_t", has_type_id = false)]
public struct Atom {
}

or as:

[SimpleType]
[CCode (cname = "xcb_atom_t", has_type_id = false)]
public struct Atom : uint32 {
}


?

Thanks.

You inherit all the methods from uint32? ;)

[Vala] difference between using IntegerType and inheriting

2014-01-05 Thread rastersoft 

Hi again:

Another doubt I have is: what is the difference between doing:

[SimpleType]
[IntegerType (rank = 9)]
[CCode (cname = "c_name", has_type_id = false)]
public struct StructName {
}

and

[SimpleType]
[CCode (cname = "c_name", has_type_id = false)]
public struct StructName : uint32 {
}

Thanks
