fr.umlv.tatoo.runtime.lexer
Class Scanner<R,B extends LexerBuffer>

java.lang.Object
  fr.umlv.tatoo.runtime.lexer.Tokenizer<R,B>
      fr.umlv.tatoo.runtime.lexer.Scanner<R,B>

Type Parameters:

R - type of rules.

B - type of buffer.

All Implemented Interfaces:

Iterable<R>, Iterator<R>

public class Scanner<R,B extends LexerBuffer>
extends Tokenizer<R,B>
implements Iterator<R>, Iterable<R>

Provide a simple scanner that implements Iterator and Iterable The buffer must support the read operation. If you don't have an activator because you don't use the parser provided by Tatoo, you can use a Tokenizer instead.
