The IDL operation
credit
is mapped to the Common Lisp generic function:
op:credit
In IDL, the
credit
operation is defined within the
account
interface, declaring it to be an operation on
account
objects. The Common Lisp language binding adopts the convention that an operation's target object should be passed as the first argument of the corresponding Common Lisp generic function. Thus the first parameter of the generic function
op:credit
is an object of type
BankingDemo:account
.
The operation's
in
and
inout
arguments become the remaining parameters of the corresponding Common Lisp generic function. In this case, the
credit
operation specifies a single
in
parameter,
in unsigned long amount
, that determines the second and only other parameter,
amount
, of the
op:credit
generic function.
The operation's result type, and any other parameters declared as
out
or
inout
, become results of the corresponding Common Lisp generic function. In this case, because the result type of
credit
is
void
, and the operation has no
out
or
inout
parameters,
op:credit
has an empty result list.
