Class "GDALTransientDataset"
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 can be created by calls of the form new("GDALTransientDataset", driver, rows, cols, bands, type, options, fname, handle).
A "GDALDriver" object that determines the storage format
Number of rows in the newly created dataset
Number of columns in the newly created dataset
Number of bands to create
A GDAL type name as listed in .GDALDataTypes
Driver specific options
default NULL, used internally to pass through a file name with a required extension (RST driver has this problem)
Used internally; not for public consumption
handle:Object of class "externalptr", from class "GDALDataset", used internally; not for public consumption
Class "GDALDataset", directly.
Class "GDALReadOnlyDataset", by class "GDALDataset".
Class "GDALMajorObject", by class "GDALDataset".
