eieio-persistent-read
eieio-persistent-read is a compiled Lisp function in `eieio-base.el
'.
(eieio-persistent-read FILENAME &optional CLASS ALLOW-SUBCLASS)
Read a persistent object from FILENAME, and return it.
Signal an error if the object in FILENAME is not a constructor
for CLASS. Optional ALLOW-SUBCLASS says that it is ok for
`eieio-persistent-read' to load in subclasses of class instead of
being pedantic.
