ZODB.Architecture.Connection.exportFile

Documentation

Export an object and all objects reachable from the object to a file.

The file consists of the string 'ZEXP' followed by a sequence of ExportFileRecords.

Parameters

Type	Name	Default	Documentation
	oid		the Object ID of the object to be exported
PyObject	file	None	The file may be either a file-like object (an object with a write method) or a file name. If a file name is provided, then the corresponding file will be created, if necessary, and opened. If no file object is specified, then a temporary file will be created and used. The file used is returned.

Note

Data are saved immediately. This means that only committed data are saved. Pending changes to the object saved, or to objects reachable from the object are not reflected in the data.
