java.lang.Object | +--fri.patterns.interpreter.parsergenerator.syntax.builder.SyntaxSeparation
Separates lexer from parser rules. Provides token and ignored symbols after construction, which can be used for LexerBuilder construction.
Example:
SyntaxSeparation separation = new SyntaxSeparation(new Syntax(myRules)); LexerBuilder builder = new LexerBuilder(separation.getLexerSyntax(), separation.getIgnoredSymbols()); Lexer lexer = builder.getLexer(); // when using the lexer standalone, you must put the token terminal symbols into it now: lexer.setTerminals(separation.getTokenSymbols()); // when using a Parser the Parser will do this:
