#' @title Class to find and/or replace the slangs on the data field of an Instance
#'
#' @description \code{\link{SlangPipe}} class is responsible for detecting
#' the existing slangs in the \strong{data} field of each \code{\link{Instance}}.
#' Identified slangs are stored inside the \strong{slang} field of
#' \code{\link{Instance}} class. Moreover if needed, is able to perform inline
#' slangs replacement.
#'
#' @section Details:
#' \code{\link{SlangPipe}} class requires the resource files (in json format)
#' containing the correspondence between slangs and meaning. To this end,
#' the language of the text indicated in the \emph{propertyLanguageName} should
#' be contained in the resource file name (ie. slang.xxx.json where xxx is the
#' value defined in the \emph{propertyLanguageName} ). The location of the
#' resources should be defined in the \strong{"resources.slangs.path"} field of
#' \emph{\link{bdpar.Options}} variable.
#'
#' @section Note:
#' \code{\link{SlangPipe}} will automatically invalidate the
#' \code{\link{Instance}} whenever the obtained data is empty.
#'
#' @section Inherit:
#' This class inherits from \code{\link{GenericPipe}} and implements the
#' \code{pipe} abstract function.
