## Class definition
#' Excess of Loss Treaty
#'
#' An S4 class to represent an Excess of Loss Treaty
#'
#' @slot ded Numeric. Deductible amount of the treaty. Should be superior to 0.
#' @slot lim Numeric. Limit amount for the treaty. Should be superior to 0. May be equal to \code{Inf}.
#' @slot aal Numeric. Annual Aggregate Deductible amount of the treaty. Should be superior to 0.
#' @slot aad Numeric. Annual Aggregate Limit amount for the treaty. Should be superior to 0. May be equal to \code{Inf}.
#' @slot rns Numeric vector. Reinstatement prices. Vector of lentgh equals to the number of reinstatements with each value equals the price of the reinstatement.
#' @slot prm Numeric. Premium rate, which represents the proportion of the premium given to the reinsurer as price for the treaty. Should be between 0 and 1.
#' @slot ptf Vector. List of portfolios on which the treaty is to be applied on.
#' @slot trt Character. Always equal to "SL". Identifier for the type of treaty
#'

## User constructor function
#' Excess of Loss Treaty: User constructor function
#'
#' \code{xl} defines an object of class \code{XL} (\code{\link{XL-class}}), which represents an Excess of Loss treaty.
#'
#' @param ded Numeric. Deductible amount of the treaty. Should be superior to 0.
#' @param lim Numeric. Limit amount for the treaty. Should be superior to 0. May be equal to \code{Inf}.
#' @param aal Numeric. Annual Aggregate Deductible amount of the treaty. Should be superior to 0.
#' @param aad Numeric. Annual Aggregate Limit amount for the treaty. Should be superior to 0. May be equal to \code{Inf}.
#' @param rns Numeric vector. Reinstatement prices. Vector of lentgh equals to the number of reinstatements with each value equals the price of the reinstatement.
#' @param prm Numeric. Premium rate, which represents the proportion of the premium given to the reinsurer as price for the treaty. Should be between 0 and 1.
#' @param ptf Vector. List of portfolios on which the treaty is to be applied on. Default value set to all.
#'
#' @return An object of class \code{XL} (\code{\link{XL-class}}), initialized with the values given in input. Its basic methods are:
#' \itemize{
#' \item{\code{show}}
#' }
#'
#' @details Reinstatements are the number of time the limit can be reconstructed. The vector given for this parameter will be an indication of the price for each reinstatement. For example, a \code{rns} value of \code{c(0, 1)} will give one free reinstatement and one reinstatement paid 100\% of the premium before totally consuming the limit.

#' @examples
#' treaty_1 <- xl(ded = 200000, lim = 20000, aad = 0,
#' aal = 10000, prm = 0.01, rns = c(0, 1))
#' treaty_1

#' @export
