Class RemoteDataPackageWrapper

This is a wrapper for data stored in a remote repository accessible via FTP. It inherits from :class:`DataPackageWrapper`. See there for the inherited methods. This class wraps not only the (remote) locations of data and metadata, but also :class:`~.CacheFileWrapper` instances for locally cached copies of the respective files. .. method:: initialize(**kwargs) In addition to the attributes declared in :meth:`DataPackageWrapper.initialize` this method accepts an optional ``cache_file`` keyword argument which is expected to be an instance of :class:`~.CacheFileWrapper`.

(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__: (inherited documentation)

getType(self)

source code

Returns ``"remote"``.

Overrides: core.records.RecordWrapper.getType

source code

Loads a remote data file into the local cache, if necessary. Never omit the call to :meth:`prepareAccess` when attempting to access a remote dataset, subsequent method calls to :meth:`open`, :meth:`getAccessibleLocation` and :meth:`getGDALDatasetIdentifier` may fail.

Overrides: DataPackageWrapper.prepareAccess

getAccessibleLocation(self)

source code

Returns the location of the locally cached data file.

Overrides: DataPackageWrapper.getAccessibleLocation

getGDALDatasetIdentifier(self)
