Runs a parent class method from within a subclass method.
Syntax
cClassName::cMethod
Remarks
The :: operator is used to execute a parent class method from within a subclass method. When you create a subclass, the subclass methods are automatically inherited from the parent class. The :: operator lets you execute the parent class method in the subclass method and then perform additional processing for the subclass method. The subclass definitions in the example demonstrate how the :: operator is used to execute the parent class method within a subclass method.
For additional information about the :: scope resolution operator, see Chapter 3, Object-Oriented Programming in the Programmer's Guide.
