+ * A sniff registers what token types it wishes to listen for, then, when
+ * PHP_CodeSniffer encounters that token, the sniff is invoked and passed
+ * information about where the token was found in the stack, and the
+ * PHP_CodeSniffer file in which the token was found.

+     * <code>

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