specialFiltersToDisallow vs disallowedSpecialFilters = difference?

[Deimos Rast]

Is there a difference between the two?
There is a "specialFiltersToAllow" but best I can tell no "allowedSpecialFilters." Logically, you would think there would be, so there probably is - I just haven't found an example in the Core game.
Mainly just curious as to which I should use in what circumstances.

            <li>AllowCorpsesStranger</li>

specialFiltersToAllow and specialFiltersToDisallow exist.
I've used ILSpy to search for those terms. Couldn't find disallowedSpecialFilters and didn't spot what the exact difference is.

private List<SpecialThingFilterDef> disallowedSpecialFilters = new List<SpecialThingFilterDef>();

Code Select Expand

private List<string> specialFiltersToAllow;
private List<string> specialFiltersToDisallow;

Code Select Expand

// Verse.ThingFilter
public bool IsAlwaysDisallowedDueToSpecialFilters(ThingDef def)
{
for (int i = 0; i < this.disallowedSpecialFilters.Count; i++)
{
if (this.disallowedSpecialFilters[i].Worker.AlwaysMatches(def))
{
return true;
}
}
return false;
}

Not sure if that helps at all.

all the ones I mentioned exist with the possible exception of allowedSpecialFilters. Just do a search of Core.
I am curious about this ILSpy though, since MonoDevelop has been under performing of late, and I really just need a search tool most of the time. Playing with it now, it looks promising.
Thanks.

No prob. I've also been trying the dotPeek thing within Visual Studio, but it's not working as easy as ILSpy is.
