roAssociativeArray Logic

Hopefully a quick question. I’m trying to learn about the roAssociativeArray, and created the following, but am getting an error “Member function not found in BrightScript Component or interface.”

Why doesn’t this work ( I copied basic syntax from a previous demo )?


Sub Main()
    Web = SetAssociativeArray() 
    Web.ThisIsOne()
End Sub

Function SetAssociativeArray() As Object
    Print "Set Array"
    Web = CreateObject("roAssociativeArray")
    Web.ThisIsOne = One
    Web.ThisIsTwo = Two
End Function

Sub One()
    Print "Hit One"
End Sub

Sub Two()
    Print "Hit Two"
End Sub

A demo project does something similar, and it compiles, so not sure what my issue is? Any advice?

Thanks

Your SetAssociativeArray function never returns an object. Add a “Return Web” to the end of it, and you should be in business.

Jeeze, man what a silly mistake. Worked like a charm.

Thanks Endless, you are the best.

Sure thing.. it may also be worth noting that your SetAssociativeArray function can be written using a different syntax that you might find preferable:

Function SetAssociativeArray() As Object
    Web = {
        ThisIsOne: One
        ThisIsTwo: Two
    }
    Return Web
End Function

Cool! That does read very nice. I’ve seen that in the reference guide, but hadn’t spent any time reading about it.

To be sure, it still creates a AssociativeArray, but I just don’t have to declare it with “CreateObject” like in my earlier code block?

Correct. Another shortcut for creating an roAssociativeArray is this syntax:

Web = {} ' creates empty roAssociativeArray 
Web.ThisIsOne = One
Web.ThisIsTwo = Two
