Method definition

Method is a subroutine.

Format is:


access-control method return-type method-name(arguments)

You can use the abbreviation em instead of endmethod.

In the class definition, it is possible to define methods of any number at any place outside the other member definitions.

access control

Access-control determines the access level by specifying a keyword either open or closed.

If it is open, you can invoke the method from outside the class definition. If it is closed, you can invoke the method only inside the class definition.

The method is a keyword which indicates this is a method. It must be present between the access-control and return-type.

return type

The return-type is a specification of a class which is returned.

You should specify a void if the method does not return a value.

Identifier and embedded class name can use for the method name.

arguments

The argument is a pair of class name and identifier in parentheses. You can specify any number of such pairs. If there are two or more pairs, they must be separated by commas.


open method void sampleMethod()

open method void sampleMethod(int index)

open method void sampleMethod(int index, string message)


There are no special keywords to indicate that there are no arguments. If there are no arguments, you do not need to specify anything in parentheses.

statements

If the return type is void, statements are optional.

If the return type is not void, a return statement is required at a minimum.
