Examples of org.antlr.runtime.ANTLRReaderStream

org.antlr.runtime.ANTLRReaderStream
Vacuum all input from a Reader and then treat it like a StringStream. Manage the buffer manually to avoid unnecessary data copying. If you need encoding, use ANTLRInputStream.

        setErrors( errors );
    return errors.isEmpty();
    }  
  
  private DSLMapping buildFileMapping(final List errors, final Reader dsl) throws IOException, RecognitionException{
    ANTLRReaderStream reader = new ANTLRReaderStream(dsl);
    DSLMapWalker walker = buildFileMappingWalker(errors, reader);
    DSLMapping mapping = walker.mapping_file();
    return mapping;
  }
