Methods have the following type modifiers:•
abstract: The method is declared but not implemented and subclasses must define it; by default the method is concrete and implemented.
• display: The method returns a value used by a field in a form or report and can’t be changed.
• edit: The method returns a value used by a field in a form.
• final: The method can’t be overridden by subclasses; this modifier can’t be used with constructors and destructors.
• static: The method is a class method and is invoked using the “::” notation on the class instead of on an object instance using the “.” notation.
