##' @title QGIS algorithm - Accumulated cost
##'
##' @param DEST_TYPE `enum` of `("(0) Point", "(1) Grid")` - Input Type of Destinations. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param DEST_POINTS `source` - Destinations. Path to a vector layer.
##' @param DEST_GRID `raster` - Destinations. Path to a raster layer.
##' @param COST `raster` - Local Cost. Path to a raster layer.
##' @param DIR_MAXCOST `raster` - Direction of Maximum Cost. Path to a raster layer.
##' @param DIR_UNIT `enum` of `("(0) radians", "(1) degree")` - Units of Direction. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param DIR_K `number` - K Factor. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
##' @param ACCUMULATED `rasterDestination` - Accumulated Cost. Path for new raster layer.
##' @param ALLOCATION `rasterDestination` - Allocation. Path for new raster layer.
##' @param THRESHOLD `number` - Threshold for different route. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
##' @param ... further parameters passed to `qgisprocess::qgis_run_algorithm()`
##' @param .complete_output logical specifying if complete out of `qgisprocess::qgis_run_algorithm()` should be used (`TRUE`) or first output (most likely the main) should read (`FALSE`). Default value is `TRUE`.
##' @param .quiet logical specifying if parameter `.quiet` for `qgisprocess::qgis_run_algorithm()` Default value is `TRUE`.
##' @param .messages logical specifying if messages from `qgisprocess::qgis_run_algorithm()` should be printed (`TRUE`) or not (`FALSE`). Default value is `FALSE`.
