| * <p> |
| * Similar in functionality to the {@link HttpServletRequest#getParameter(String)} except only looks in the body of the request, not parameters from |

| * <br>This can be useful in cases where you're using GET parameters on FORM POSTs, and you don't want the body of the request to be read. |

| * <p> |
| * Use of this object is incompatible with using any other methods that access the body of the request (since this object will |

| * <li class='jm'>{@link RestRequest#getBody()} |
