NAME

GenOO::GeneCollection::Factory::GTF - Factory to create GeneCollection from a GTF file

SYNOPSIS

Creates GenOO::GeneCollection containing genes from a GTF file Preferably use it through the generic GenOO::GeneCollection::Factory

    my $factory = GenOO::GeneCollection::Factory->new('GTF',{
        file => 'sample.gtf'
    });

DESCRIPTION

    An instance of this class is a concrete factory for the creation of a 
    L<GenOO::GeneCollection> containing genes from a GTF file. It offers the method 
    "read_collection" (as the consumed role requires) which returns the actual
    L<GenOO::GeneCollection> object in the form of 
    L<GenOO::RegionCollection::Type::DoubleHashArray>. The latter is the implementation
    of the L<GenOO::RegionCollection> class based on the complex data structure
    L<GenOO::Data::Structure::DoubleHashArray>.

EXAMPLES

    # Create a concrete factory
    my $factory_implementation = GenOO::GeneCollection::Factory->new('GTF',{
        file => 'sample.gtf'
    });
    
    # Return the actual GenOO::GeneCollection object
    my $collection = $factory_implementation->read_collection;
    print ref($collection) # GenOO::GeneCollection::Type::DoubleHashArray
