Compare with:

assign_multiparameter_attributes(pairs)

Instantiates objects for all attribute classes that needs more than one constructor parameter. This is done by calling new on the column type or aggregation type (through composed_of) object with these parameters. So having the pairs written_on(1) = “2004”, written_on(2) = “6”, written_on(3) = “24”, will instantiate written_on (a date type) with Date.new(“2004”, “6”, “24”). You can also specify a typecast character in the parentheses to have the parameters typecasted before they’re used in the constructor. Use i for Fixnum, f for Float, s for String, and a for Array. If all the values for a given attribute are empty, the attribute will be set to nil.
