Table FOO has a foreign key reference to BAR, so a many-to-one relationship exists.
Foo will contain a getBar() method. Bar will contain a getFoos(Criteria).
There are several more methods that can get generated depending on many-to-many
relationships. So for example if FOO also contains a fk to XXX, then Bar will contain
a
method getFoosJoinXxx(Criteria). This method will return a collection of Foos in much
the
same way as the getFoos method but the Foo's will be prefilled with their related Xxx
objects, so that
Vector v = getFoos(c);
loop over v
print v(i).getXxx().getName();
end loop
Vector v = getFoosJoinXxx(c);
loop over v
print v(i).getXxx().getName();
end loop
will lead to the exact same listing, the second method will use a join to grab all the
data at once. The first method will have one db access to get the Foo's and then one
db
hit per getXxx() method.
