\title{Class \code{"LinearMethodsList"}}

\description{

  A version of methods lists that has been \sQuote{linearized}

  for producing summary information.  The actual objects from class

  \code{"MethodsList"} used for method dispatch are defined recursively

  over the arguments involved.

}

\section{Objects from the Class}{

  The function \code{\link{linearizeMlist}} converts an ordinary methods

  list object into the linearized form.

}

\section{Slots}{

  \describe{

    \item{\code{methods}:}{Object of class \code{"list"}, the method

      definitions.}

    \item{\code{arguments}:}{Object of class \code{"list"}, the

      corresponding formal arguments, namely as many of the arguments

      in the signature of the generic function as are active in the

      relevant method table. }

    \item{\code{classes}:}{Object of class \code{"list"}, the

      corresponding classes in the signatures. }

    \item{\code{generic}:}{Object of class \code{"genericFunction"};

        the generic function to which the methods correspond. }

  }

}

\section{Future Note}{

  The current version of \code{linearizeMlist} does not take advantage of

  the \code{MethodDefinition} class, and therefore does more work for less

  effect than it could.  In particular, we may move to redefine both the

  function and the class to take advantage of the stored signatures.

  Don't write code depending precisely on the present form, although all

  the current information will be obtainable in the future.
