Pipeline::Store::ISA - inheritance-based store for pipelines
use Pipeline::Store::ISA;
my $store = Pipeline::Store::ISA->new();
$store->set( $object );
my $object = $store->get( $class );
"Pipeline::Store::ISA" is a slightly more
complex implementation of a Pipeline store than
"Pipeline::Store::Simple". It stores things
as in a hashref indexed by classname, and also their inheritance tree. You can
add an object to a store by calling the set method with an object, and you can
get an object by calling the get method with the classname or parent classname
of the object you wish to retrieve.
"Pipeline::Store::ISA" inherits
from the "Pipeline::Store" class and
includes its methods also.
- set( OBJECT )
- The "set" method stores an object
specified by OBJECT in itself. Replaces existing objects of the same
type.
- get( SCALAR )
- The "get" method attempts to return an
object of the class specified by SCALAR. If an object of that class does
not exist in the store it returns undef instead. In the case that you
request a super class of multiple objects an array reference will be
returned containing all the objects that are blessed into child classes of
SCALAR.
