Set this to a true value for a column whose value is retrieved automatically
from a sequence or function (if supported by your Storage driver.) For a
sequence, if you do not use a trigger to get the nextval, you have to set the

An accessor to set a callback to be called during deployment of

The callback can be set as either a code reference or the name of a
method in the current result class.
