Bio::Factory::ObjectFactory - Instantiates a new Bio::Root::RootI (or derived class) through a factory
use Bio::Factory::ObjectFactory; my $factory = Bio::Factory::ObjectFactory->new(-type => 'Bio::Ontology::GOterm'); my $term = $factory->create_object(-name => 'peroxisome', -ontology => 'Gene Factory', -identifier => 'GO:0005777');
This object will build Bio::Root::RootI objects generically.
User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing list. Your participation is much appreciated.

Please direct usage questions or support issues to the mailing list:
rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

This is mostly copy-and-paste with subsequent adaptation from Bio::Seq::SeqFactory by Jason Stajich. Most credits should in fact go to him.
The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Title : new Usage : my $obj = Bio::Factory::ObjectFactory->new(); Function: Builds a new Bio::Factory::ObjectFactory object Returns : Bio::Factory::ObjectFactory Args : -type => string, name of a L<Bio::Root::RootI> derived class. There is no default. -interface => string, name of the interface or class any type specified needs to at least implement. The default is Bio::Root::RootI.
Title : create_object Usage : my $seq = $factory->create_object(<named parameters>); Function: Instantiates a new object of the previously set type. This object allows us to genericize the instantiation of objects. You must have provided -type at instantiation, or have called type($mytype) before you can call this method. Returns : an object of the type returned by type() The return type is configurable using new(-type =>"..."), or by calling $self->type("My::Fancy::Class"). Args : Initialization parameters specific to the type of object we want. Check the POD of the class you set as type.
Title : type Usage : $obj->type($newval) Function: Get/set the type of object to be created. This may be changed at any time during the lifetime of this factory. Returns : value of type (a string) Args : newvalue (optional, a string)
Title : interface Usage : $obj->interface($newval) Function: Get/set the interface or base class that supplied types must at least implement (inherit from). Example : Returns : value of interface (a scalar) Args : on set, new value (a scalar or undef, optional)
Title : _validate_type Usage : $factory->_validate_type($object) Function: Called to let derived factories validate the type set via type(). The default implementation here checks whether the supplied object skeleton implements the interface set via -interface upon factory instantiation. Example : Returns : TRUE if the type is to be considered valid, and FALSE otherwise. Instead of returning FALSE this method may also just throw an informative exception. The default implementation here will throw an exception if the supplied object does not inherit from the interface provided by the interface() method. Args : A hash reference blessed into the specified type, allowing queries like isa().
