dtRdr::Annotation::Range - range-derived annotations
Required for all annotations. Any annotation derived from this class is a range type, so this is just a constant.
Must be implemented by subclasses.
Change the node of an annotation object. The resultant object cannot be used for serialization.
my $new_obj = $obj->renode($node, %props);
Create a new (not unlinked) copy of an object with different properties.
$new_obj = $obj->dummy(%props);
Overrides the range get_book alias.
The annotation storage (dtRdr::Annotation::IO) classes expect annotations objects to support serialize() and deserialize() methods. These methods transform an object to/from a plain hash reference (i.e. there are no linked objects, circular references, etc.)
Returns a hashref which contains no book object or other circular references.
my $plain_hashref = $object->serialize;
A subclass may define this method to add properties to the serialized hash reference.
%props = $object->augment_serialize;
Transform the stripped-down hashref (as returned by serialize()) into a proper object.
my $object = MyClass->deserialize($hashref, book => $book);
May be defined by a subclass to augment the deserialization. The returned properties will be added to the arguments to new().
%props_out = SubClass->augment_deserialize(%props_in);
Creates a (mostly) detatched version of the object. (use sparingly)
