es.litesolutions.sonar.grappa.CodeReaderListener

public final class CodeReaderListener
extends com.github.fge.grappa.run.ParseRunnerListener<com.sonar.sslr.api.Token.Builder>

A parsing listener associated with a Sonar CodeReader and Lexer

This listener will handle both the consumption of characters from the code reader, and adding tokens to the lexer.

For this, it captures the root matcher obtained from the initial context (see beforeParse(PreParseEvent)) and waits for this matcher to reappear at level 0. When it reappears, it means the parsing is done, whether successful or not.

After the parsing is done, the consumed characters are popped from the reader and the recorded tokens are added to the lexer.
