NAME

GenOO::RegionCollection::Factory::GTF - Factory for creating a TranscriptCollection with transcripts from a GTF file

SYNOPSIS

    # Creates GenOO::TranscriptnCollection containing transcripts from a GTF file 

    # Preferably use it through the generic GenOO::TranscriptCollection::Factory
    my $factory = GenOO::TranscriptCollection::Factory->new('GTF',
        {
            file => 'sample.gtf'
        }
    );

DESCRIPTION

    An instance of this class is a concrete factory for the creation of a 
    L<GenOO::TranscriptCollection> containing transcripts from a GTF file. It offers the method 
    "read_collection" (as the consumed role requires) which returns the actual
    L<GenOO::TranscriptCollection> 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::TranscriptCollection::Factory->new('GTF',
        {
            file => 'sample.gtf'
        }
    );
    
    # Return the actual GenOO::RegionCollection object
    my $collection = $factory_implementation->read_collection;
    print ref($collection) # GenOO::RegionCollection::Type::DoubleHashArray
