Pipeline::Store::ISA - inheritance-based store for pipelines
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.
