Abstract

Specifies whether this is an abstract parameter.

Usage

To specify that this parameter is abstract, use the following syntax:

Parameter name As parameter_type [ Abstract ] = value ;

Otherwise, omit this keyword or place the word Not immediately before the keyword.

Details

An abstract parameter simply behaves as if it were not defined. However, users can define an abstract parameter for documentation purposes and in order to enforce the signature of this parameter to be defined in the subclasses.

Default

If you omit this keyword, the parameter is not abstract.
