HasUniqueMultiOutputAttributes - BHoM/documentation GitHub Wiki

Severity - Fail

Check method - Here

The HasUniqueMultiOutputAttributes check ensures that a method returning a type of Output<t, ..., tn> has a matching number of MultiOutput attributes that have unique indexes.

For example, a method returning Output<Panel, Opening> would require 2 uniquely indexed MultiOutput attributes to document both the Panel and the Opening.

If the method looked like the below, while containing 2 MultiOutput attributes, would fail this check, because the index for both outputs cannot be 0.

[MultiOutput(0, "panel")]
[MultiOutput(0, "opening")]
public static Output<Panel, Opening> MyTestMethod()
{
}

The method should instead look like this:

[MultiOutput(0, "panel")]
[MultiOutput(1, "opening")]
public static Output<Panel, Opening> MyTestMethod()
{
}

Where the index of the MultiOutput attributes is unique.
