Example Structure defstruct 002

 

 

Description

This example defines a new type object type name using the defstruct function. This new object type inherits the the previously define employee object type.

 

Details

The object type "manager" inherits all the field names from the "employee" object and adds a new field named perks:

(defstruct manager: include: employee: perks:) Returns: manager

Create an instance of the employee object using a constructor function and initializers.

(define W (new manager: perks: "parking")) Returns: manager

The properties of Structure W of the "manager" object type are displayed.

(display W.name) Returns: #void true
(display W.job) Returns: #void true
(display W.salary) Returns: #void true
(display W.perks) Returns: parking

The child type inherits the type from the parent object.

(isType manager: W ) Returns: true
(isType employee: W ) Returns: true

Z, an object of "employee" type is not of type "manager" since a parent object does not inherit the type from the child type. (Please see Example_Structure_defstruct_001 for the definition and instanciation of "employee".)

(isType manager: Y ) Returns: false
