RE: What happens to 'def' attributes in scripts?

Great thanks,

Just as I expected. That leads me to the following questions..

1) Why does methods have to be def'ed.

2) How can I specify the type of my attribute?

Some of the users have programming experience and

a) either want def func() and def var to be consistent

b) by mistake write int n=1 very often.

It just seems a bit inconsistent to me.

Woo, I can answer this one.

When groovyc compiles this script it has to convert into java byte code. So, the n=1 become Test instance attributes, the def n=1 become main method local variables.

The case without def results in java looking something like this:

    class Test
    {
        Object n = 1
        Object m = 2

        public static void main(String args[])
        {
            add(m)
        }

        void add(Object another)
        {
            another += n
        }
    }

this works because there are no defs and the scoping of n and m remain accessible by the add method

However, add the def and they become local variables in the main method and now are not accessible by add.

    class Test
    {
        public static void main(String args[])
        {
            Object n = 1
            Object m = 2

            add(m)
        }

        void add(Object another)
        {
            another += n
        }
    }
