Detailed Description

The Driver class brings together all components. It creates an instance of the Parser and Scanner classes and connects them. Then the input stream is fed into the scanner object and the parser gets it's token sequence. Furthermore the driver object is available in the grammar rules as a parameter. Therefore the driver class contains a reference to the structure into which the parsed data is saved.
