NAME

AI::Categorizer::Storable - Saving and Restoring State

SYNOPSIS

  $object->save_state($path);
  ... time passes ...
  $object = Class->restore_state($path);
  

DESCRIPTION

This class implements methods for storing the state of an object to a file and restoring from that file later. In AI::Categorizer it is generally used in order to let data persist across multiple invocations of a program.

METHODS

save_state($path)

This object method saves the object to disk for later use. The $path argument indicates the place on disk where the object should be saved.

restore_state($path)

This class method reads the file specified by $path and returns the object that was previously stored there using save_state().
