| \title{Internal Class representing Empty Methods List } |
| \description{ |
| Objects from class \code{"EmptyMethodsList"} are generated during |
| method selection to indicate failed search (forcing backtracking). |
| Other classes described here are used internally in method dispatch. |
| All these are for internal use.} |
| \usage{ |
| ## class described below |
| "EmptyMethodsList" |
| |
| ### Other, virtual classes used in method dispatch |
| "OptionalMethods" |
| "PossibleMethod" |

| \section{Slots}{ |
| \describe{ |
| \item{\code{argument}:}{Object of class \code{"name"} the argument |
| names being selected on.} |
| \item{\code{sublist}:}{Object of class \code{"list"} (unused, and |
| perhaps to be dropped in a later version.) } |
| } |
| } |
| |
| \section{Methods}{ |
| No methods defined with class \code{"EmptyMethodsList"} in the |
| signature. |

| Function \code{\link{MethodsListSelect}} (deprecated since \R version |
| 3.2.0) uses the objects; |
| class \code{\linkS4class{MethodsList}} is formally defunct since \R 3.2.0. |
