Examples of ParserTables

fri.patterns.interpreter.parsergenerator.ParserTables
Responsibilities of (bottom-up) parser tables, that must provide:
- all terminals, without EPSILON (for the Lexer)
- the syntax
- the follow-state from the GOTO-table
- the follow action from the PARSE-ACTION-table
- a list of expected terminals
