NAME

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

CONTENTS

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.

FEEDBACK

    Mailing Lists

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.

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().
