Unknown data storage location for ioPort with reading def

[inv1s10n]

I found that in Class dbBTerm and dbBPin, only the boxes but no location. Where is the location in def for the pins storaged? Thank you.

The location is just used to give the boxes their coordinates and has no meaning by itself. In defout we pick an arbitrary point (center of the first box in the first bpin) as the location.
