The Storable extension brings persistency to your data.
|
|
|
|
You may recursively store to disk any data structure, no matter how
|
|
complex and circular it is, provided it contains only SCALAR, ARRAY,
|
|
HASH (possibly tied) and references (possibly blessed) to those items.
|
|
|
|
At a later stage, or in another program, you may retrieve data from
|
|
the stored file and recreate the same hiearchy in memory. If you had
|
|
blessed references, the retrieved references are blessed into the same
|
|
package, so you must make sure you have access to the same perl class
|
|
as the one used to create the relevant objects.
|
|
|
|
There is also a dclone() routine which performs an optimized mirroring
|
|
of any data structure, preserving its topology.
|
|
|
|
Objects (blessed references) may also redefine the way storage and
|
|
retrieval is performed, and/or what deep cloning should do on those
|
|
objects.
