ABENOBJECT_REFERENCE_TYPE - OBJECT REFERENCE TYPE

Object References

Object references can point to instances of classes. The static type of their reference variables is either a class or an interface. Both types can be used to create objects with the statement CREATE OBJECT.

• Class reference variables allow access to all visible components of a class.

• Interface reference variables restrict the view of the interface components of a class.

If an attempt is made to access an instance attribute using an object reference variable that contains the null reference, an uncatchable exception is raised. A catchable exception is raised when an instance method is called.

Object references are always heap references.

Note

For more information, see Object References.

Example
