NAME

GenOO::RegionCollection::Type::DoubleHashArray - Object for a collection of GenOO::Region objects, with features

SYNOPSIS

    # Object that manages a collection of GenOO::Region objects. 

    # To initialize 
    my $locus_collection = GenOO::RegionCollection::DoubleHashArray->new({
        name          => undef,
        species       => undef,
        description   => undef,
        extra         => undef,
    });

DESCRIPTION

    The primary data structure of this object is a 2D hash whose primary key is the strand 
    and its secondary key is the reference sequence name. Each such pair of keys correspond to an
    array reference which stores objects of the class L<GenOO::Region> sorted by start position.

EXAMPLES

    # Print records in FASTA format
    $locus_collection->print("FASTA",'STDOUT',"/data1/data/UCSC/hg19/chromosomes/");
    
    # ditto
    $locus_collection->print_in_fasta_format('STDOUT',"/data1/data/UCSC/hg19/chromosomes/");
