+ * information about where the token was found in the stack, and the
+ * PHP_CodeSniffer file in which the token was found.

+     * <code>
+     *    $tokens = $phpcsFile->getTokens();

+     * If the sniff discovers an anomaly in the code, they can raise an error
+     * by calling addError() on the \PHP_CodeSniffer\Files\File object, specifying an error
+     * message and the position of the offending token:
+     *

+     *                                               token was found.
+     * @param int                         $stackPtr  The position in the PHP_CodeSniffer
+     *                                               file's token stack where the token
