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
