\title{Class "FarmRepresentation" }
\description{Abstract Class providing generic methods to access properties of Farm objects}
\section{Objects from the Class}{A virtual Class: No objects may be created from it.}
\section{Methods}{
  \describe{
    \item{cropArea}{\code{signature(farm = "FarmRepresentation", cropName = "character")}: The area in hectares of the named crop. Should only be called on solved farm objects }
    \item{cropNames}{\code{signature(object = "FarmRepresentation")}: A string vector with the names of all crops defined for this farm }
    \item{eo}{\code{signature(farm = "FarmRepresentation")}: Enterprise output of the farm }
    \item{guts}{\code{signature(object = "FarmRepresentation")}: Dump the internal representation of the farm to the screen. This is not pretty }
    \item{isSolved}{\code{signature(farm = "FarmRepresentation")}: Returns 1 if the farm has been solved, 0 if not }
    \item{model}{\code{signature(farm = "FarmRepresentation")}: Get a reference to the internal java reference representing this farm }
    \item{objectiveNames}{\code{signature(object = "FarmRepresentation")}: A string vector with the names of objectives that will be optimised in a call to solvelp }
    \item{objectiveScaleFactors}{\code{signature(farm = "FarmRepresentation")}: A numeric vector with the relative weights (normalized) of objectives }
    \item{objectiveValues}{\code{signature(farm = "FarmRepresentation")}: Get the values of the objectives. Should only be called for solved farms }
    \item{profit}{\code{signature(farm = "FarmRepresentation")}: Get the value of the profit objective }
    \item{setInputCost}{\code{signature(farm = "FarmRepresentation", inputName = "character", inputCost = "numeric")}: Set the value of a particular input (potential values are \code{"Input","Machinery","Fuel","Labour","AreaSubsidy"}) }

	\item{constrainArea}{\code{signature(farm = "FarmRepresentation", cropName = "character", lb = "numeric")}: Constrain the area of a particular crop on a farm to be the value \code{lb}. If an optional \code{ub} argument is supplied the constraint is to hold the area of the crop between lb and ub }

    \item{show}{\code{signature(object = "FarmRepresentation")}: Print a summary of the Farm to the screen }
    \item{solvelp}{\code{signature(farm = "FarmRepresentation")}: Solve the Model }
	 }
