How can I create a dispatch table in Boo?

I'd like to be able to store a function in a hashtable. I can create a map like:

hash = {}
hash["one"] = def():
   print "one got called"

But I'm not able to call it:

func = hash["one"]
func()

This produces the following error message: It is not possible to invoke an expression on type 'object'. Neither Invoke or Call works.

How can I do it ? From what I'm guessing, the stored function should be cast to something.

Solution

  • You need to cast to a Callable type:

    hash = {}
hash["one"] = def ():
   print "one got called"

func = hash["one"] as callable
func()
