Module Name:
|
|
- Renderer.hpp
|
|
|
|
Abstract:
|
|
- This is the definition of our renderer.
|
|
- It provides interfaces for the console application to notify when various portions of the console state have changed and need to be redrawn.
|
|
- It requires a data interface to fetch relevant console structures required for drawing and a drawing engine target for output.
