Wizard::SaveAble - A package for automatically saved objects.
# Tell a SaveAble object that it's modified $obj->Modified(1); # Tell the SaveAble object to store itself back to disk $obj->Store();
An object of the class Wizard::SaveAble is something that knows whether it has to be saved or not. To that end it offers methods like Modified and Store.
All methods are throwing a Perl exception in case of errors.
# Create an empty SaveAble object and associate a file name to it. my $obj = Wizard::SaveAble->new('file' => $file); # Load a SaveAble object from a file. my $obj = Wizard::SaveAble->new($file); # Same thing, but creating an empty object if $file doesn't exist my $obj = Wizard::SaveAble->new('file' => $file, 'load' => 1);
(Class method) There are two possible constructors for the Wizard::SaveAble class: The first is creating an empty object, you typically use a subclass of Wizard::SaveAble here. The most important attribute is the file name where the object should later be stored.
The other constructor is loading an already existing object from a file. The object is automatically blessed into the same class again, typically a subclass of Wizard::SaveAble.
# Tell an object that it's modified $obj->Modified(1); # Query whether an object is modified $modified = $obj->Modified()
(Instance methods) The Modified method is used to determine whether an object needs to be saved or not.
# Set the objects associated file $obj->File($file); # Query the objects associated file $file = $obj->File();
$obj->Store();
(Instance Method) The object is stored back to disk into the file that was fixed within the constructor.
