Marshalling of 'ncdf4' objects

Marshalling of 'ncdf4' objects

Usage

# S3 method for class 'ncdf4'
marshal(x, ...)

# S3 method for class 'ncdf4'
marshallable(...)

Arguments

x

A ncdf4:ncdf4 object.

...

Not used.

Value

A marshalled object as described in marshal().

Details

base::readBin() is used to produce a marshalled version of the original object. base::writeBin() and ncdf4::nc_open() are used to reconstruct a version of the original object from the marshalled object.

Examples

if (requireNamespace("ncdf4", quietly = TRUE)) {
  library(ncdf4)
  
  ## Create a temporary NCDF file
  tf <- tempfile(fileext = ".nc")
  
  x <- ncvar_def("x", units = "count", dim = list())
  nf <- nc_create(tf, x)
  ncvar_put(nf, x, 42)
  print(nf)
  nc_close(nf)
  rm(list = c("nf", "x"))

  ## Open NCDF file
  nf <- nc_open(tf)
  y <- ncvar_get(nf, "x")

  ## Marshal
  nf_ <- marshal(nf)

  ## Unmarshal
  nf2 <- unmarshal(nf_)

  y2 <- ncvar_get(nf2, "x")
  stopifnot(identical(y2, y))
}
