NAME

       Bio::Factory::ObjectFactory - Instantiates a new Bio::Root::RootI (or derived class)
       through a factory

SYNOPSIS

           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');

DESCRIPTION

       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.

   Support
       Please direct usage questions or support issues to the mailing list:

       bioperl-l@bioperl.org

       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.

   Reporting Bugs
       Report bugs to the Bioperl bug tracking system to help us keep track of the bugs and their
       resolution. Bug reports can be submitted via the web:

APPENDIX

       The rest of the documentation details each of the object methods.  Internal methods are
       usually preceded with a _

   new
        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.

   create_object
        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.

   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)

   interface
        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)

   _validate_type
        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().
