Purpose
External method definition for a class
Syntax
METHOD <class-name> :: <method-name>
See Also
Description
An object encapsulates methods that perform operations on the object. Encapsulation hides methods within an object, and makes the object into a fully self-contained operational unit. The METHOD command allows you to define an external method outside the CLASS...ENDCLASS construct. This allows for a procedural library of methods, or for each method to be stored in a separate physical file. An external method can have a parameter list defined with the PARAMETER command. The RETURN command should be used to define the end of the external method.
| Keyword | Description |
|---|---|
| <class-name> | The <class-name> to which the method belongs. |
| :: | The :: operator is used as a separator between the class name and method name. |
| <method-name> | A unique <method-name> of up to 32 characters must be specified. This will be the name used in the METHOD clause in the CLASS...ENDCLASS construct. |
Example
class myclass // Define properties property color as character property size as numeric // Define external methods method display external // Define internal methods method update .... return endclass // External method for 'myclass' class method myclass::display parameters whatever ... return
Products
Recital Server, Recital
