guidance on databases in logic machine

[admin]

In most cases you don't need to access internal database directly but use provided functions instead. To get all objects you can use grp.all(): http://openrb.com/docs/lua.htm#grp.all

Here's an example that logs group address, name and current value for first 5 objects:

Code:

objects = grp.all()

for i, object in ipairs(objects) do
  log(object.address, object.name, object.value)
  if i == 5 then
    break
  end
end
