public interface BarcodeLogicHandler

This is the basic interface for logic handlers. This interface usually gets implemented by classes that want to render a barcode in a specific output format. Due to different barcode types (1D, 2D) there are different descendants of this interface that define the specifics. See this interface's descendants for more information.
The purpose of this interface is to enable the separatation of barcode logic and painting/rendering logic.
