NAME

GenOO::GeneCollection::Factory::FromTranscriptCollection - Factory for creating GenOO::GeneCollection object from a Transcript Collection and a hash{transcript_name} = genename

SYNOPSIS

# Creates GenOO::RegionCollection object from a Transcript Collection and a hash 

# Preferably use it through the generic GenOO::GeneCollection::Factory
my $factory = GenOO::GeneCollection::Factory->create(
    'FromTranscriptCollection',
    {
        annotation_hash => \%annotation,
        transcript_collection => $transcript_collection
    }
);

DESCRIPTION

An instance of this class is a concrete factory for the creation of a 
L<GenOO::RegionCollection> object from a Transcript Collection (also a L<GenOO::RegionCollection> object)
and a hash that has transcript names as keys and gene names as values. 
It offers the method "read_collection" (as the consumed role requires) which returns the actual
L<GenOO::RegionCollection> 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->create(
    'FromTranscriptCollection',
    {
        annotation_hash => \%annotation,
        transcript_collection => $transcript_collection
    }
);

# Return the actual GenOO::RegionCollection object
my $collection = $factory_implementation->read_collection;
print ref($collection) # GenOO::RegionCollection::Type::DoubleHashArray
