Abstract:
|
|
|
|
The MESSAGE class provides a dummy implementation of a message displayer
|
|
class. Message displayers are meant to be used by applications to
|
|
relay information to the user. Many functions will require a 'MESSAGE'
|
|
parameter through which to relay their output.
|
|
|
|
This particular implementation of this concept will do nothing. It
|
|
will be used by users who do not wish to have any output from their
|
|
applications.
|
|
|
|
Additionally, this class serves as a base class to real implementations
|
|
of the virtual methods.
