Method Structure

A C-- method has the following structure:

disallow_overrides;
arg arg1, arg2, ..., [rest];
var var1, var2, ...;

statement1
statement2
.
.
.
The disallow_overrides; declaration indicates a non-overridable method (see Inheritance). Normally, you should omit this declaration.

The arg declaration gives a list of argument variables, whose values will correspond to the arguments passed with the message. You may omit the arg declaration if the method does not take any arguments. If the final argument variable is given in square brackets (that is, if you specify rest), then the method can accept a variable number of argments; rest will contain a list of the arguments beyond the ones corresponding to the argument variables. If you do not specify rest, then the method can accept only the number of arguments specified by the argument variables, no more.

The var declaration tells the compiler that the listed identifiers should refer to local variables. You may omit the var declaration if you do not wish to declare any local variables.

The statements statement1, statement2, ... are the body of the method. They tell the interpreter what the method does.
