GDALTransientDataset-class {rgdal} | R Documentation

## Class "GDALTransientDataset"

### Description

`GDALTransientDataset` is identical to `GDALDataset-class` except that transient datasets are not associated with any user-visible file. Transient datasets delete their associated file data when closed. See `saveDataset` and `saveDatasetAs`.

### Objects from the Class

Objects can be created by calls of the form `new("GDALTransientDataset", driver, rows, cols, bands, type, options, handle)`.

driver
  A "GDALDriver" object that determines the storage format
rows
  Number of rows in the newly created dataset
cols
  Number of columns in the newly created dataset
bands
  Number of bands to create
type
  A GDAL type name as listed in `.GDALDataTypes`
options
  Driver specific options (currently ignored)
handle
  Used internally; not for public consumption

### Slots

`handle`:
  Object of class `"externalptr", from class "GDALDataset"`, used internally; not for public consumption

### Extends

Class `"GDALDataset"`, directly. Class `"GDALReadOnlyDataset"`, by class "GDALDataset". Class `"GDALMajorObject"`, by class "GDALDataset".

### Methods

closeDataset
  `signature(dataset = "GDALTransientDataset")`: ...
initialize
  `signature(.Object = "GDALTransientDataset")`: ...
