I was playing around a bit and I'm glad to say that I can defined
methods like
this:
Sub set(name as String, assigns value as String)
Sub set(name as String, assigns value as Integer)
Function get(name as String) As String
Function get(name as String) As Integer
but then I run into trouble when I want to use them
dim i as Integer
dim s as String
p.set("hello") = 5
p.set("piff") = "Hejsan"
That works just fine, but unfortunately this doesn't work
i = p.get("hello")
s = p.get("piff")
I get a message like this for each of the last two lines "There are
several
items with this name and it is not clear which one the call refers
to".
Is there some way I can get RB to recognize that the expected
return type? Is
there some way I can get this to work?
You can write one method like this:
Function get(name as String) As Variant
Which is a "loose" type variable which will attempt to convert the
return value into the fixed variable type (string, integer, etc).
Variants are the same variables used by REALbasic in the Dictionary
and other similar classes. There are a few disadvantages, but there
are a number of advantages too. Look up Variant in the Language
Reference, and to tell what Type of data the variant stores, lookup
Variant.Type() and VarType.
