Make any modifications to object recovered from cacheRepo

This is a generic definition that can be extended according to class.

.prepareOutput(object, cacheRepo, ...)

# S4 method for Raster
.prepareOutput(
  object,
  cacheRepo,
  drv = getOption("reproducible.drv", RSQLite::SQLite()),
  conn = getOption("reproducible.conn", NULL),
  ...
)

# S4 method for ANY
.prepareOutput(object, cacheRepo, ...)

Arguments

object	Any R object
cacheRepo	A repository used for storing cached objects. This is optional if Cache is used inside a SpaDES module.
...	Arguments passed to FUN
drv	an object that inherits from DBIDriver, or an existing DBIConnection object (in order to clone an existing connection).
conn	A DBIConnection object, as returned by dbConnect().

Value

The object, modified

Examples

a <- 1
.prepareOutput(a) # does nothing
#> [1] 1

b <- "Null"
.prepareOutput(b) # converts to NULL
#> NULL

library(raster)
r <- raster(extent(0,10,0,10), vals = 1:100)

# write to disk manually -- will be in tempdir()
r <- writeRaster(r, file = tempfile())

# copy it to the cache repository
r <- .prepareOutput(r, tempdir())
