Re: [cdt-dev] Creating a CDT_INCLUDE IPathEntry for a filesystem path

[<cebarne2@xxxxxxxxxxxxxxxxxxx>]

Thanks!  Works great.

On a side note, is:

toArray(new IPathEntry[checkedPaths.size()])

a better, more efficient way to get an array from a vector beside:

toArray(new IPathEntry[0])

?

I usually use the zero-sized array argument so I never make a mistake on
the size (example below I used the {} notation).  But, if your example is
faster under-the-hood, I think I'll try it going forward.

Thanks,

Chad
