The Storable package brings you persistency for your perl
|
|
data structures containing SCALAR, ARRAY, HASH or REF
|
|
objects, i.e. anything that can be convenientely stored to
|
|
disk and retrieved at a later time.
|
|
|
|
It can be used in the regular procedural way by calling
|
|
store with a reference to the object to store, and
|
|
providing a file name. The routine returns undef for I/O
|
|
problems or other internal error, a true value otherwise.
|
|
Serious errors are propagated as a die exception.
|
|
|
|
To retrieve data stored to disk, you use retrieve with a
|
|
file name, and the objects stored into that file are
|
|
recreated into memory for you, and a reference to the root
|
|
object is returned. In case an I/O error occurred while
|
|
reading, undef is returned instead. Other serious errors
|
|
are propagated via die.
