Recursive type structures for references

[Tomi Maila]

Hi,

I'd really like to see support for recursive typing also outside LVOOP so that a reference type such as a queue could refer to the type that encloses the reference type. I see no reason why not to support such types. Reference types are not allocated at compile time so there would be no infinite memory allocations.

Example 1: Linked list

Typdef List.ctl

{

Element : I32

Queue : Queue of List.ctl

}

Example 2: Tree

Typdef Tree.ctl

{

Element : I32

Children : Array of (Queue of Tree.ctl)

}

Example 3: Recursive VI

VI Recursive.vi

{

Connector Pane

{

reference : Strictly_typed_VI of Recursive.vi

}

}

I tested this last case as I wasn't sure if this would work but it doesn't. The strictly typed VI reference on the connector pane doesn't act like a typedef so it doesn't update as VI connector pane gets updated. As a result when you browse for a connector pane type and select the VI itself, it uses a fixed connector pane before the connector pane change and doesn't dynamically update the connector pane change to the reference on the connector pane. Simple
