Function

The PROPERTY statement assigns an object data variable operand as the implementation to a property, outside an interface definition.

It is used if the interface definition in question is included from a copycode and is to be implemented in a class-specific way.

It may only be used within the DEFINE CLASS statement and after the interface definitions.

The interface and property names specified must be defined in the INTERFACE clause of the DEFINE CLASS statement.

Syntax Description

Syntax Element	Description
property-name	Property Name: This is the name assigned to the property.
OF interface-name	Interface Name: This is the name assigned to the interface.
IS operand	IS Clause: The operand in the IS clause assigns an object data variable as the place to store the property value.
END-PROPERTY	End of PROPERTY Statement: The Natural reserved word END-PROPERTY must be used to end the PROPERTY statement.

Example

The example contained in the documentation of the METHOD statement shows how the same interface is implemented differently in two classes, and how the PROPERTY statement and the METHOD statement are used to achieve this.
