NAME

       Bio::PhyloNetwork::FactoryX - Module to sequentially generate Phylogenetic Networks

SYNOPSIS

        use strict;
        use warnings;

        use Bio::PhyloNetwork;
        use Bio::PhyloNetwork::Factory;

        # Will generate sequentially all the 4059 binary tree-child phylogenetic
        # networks with 4 leaves

        my $factory=Bio::PhyloNetwork::Factory->new(-numleaves=>4);

        my @nets;

        while (my $net=$factory->next_network()) {
          push @nets,$net;
          print "".(scalar @nets).": ".$net->eNewick()."\n";
        }

DESCRIPTION

       Sequentially builds a (binary tree-child) phylogenetic network each time next_network is
       called.

       The rest of the documentation details each of the object methods.

   new
        Title   : new
        Usage   : my $factory = new Bio::PhyloNetwork::Factory();
        Function: Creates a new Bio::PhyloNetwork::Factory
        Returns : Bio::PhyloNetwork::RandomFactory
        Args    : -numleaves => integer
                   OR
                  -leaves => reference to an array (of leaves names)
                  -numhybrids => integer [default = numleaves -1]
                  -recurse => boolean [optional]

       Returns a Bio::PhyloNetwork::Factory object. Such an object will sequentially create
       binary tree-child phylogenetic networks each time next_network is called.

       If the parameter -leaves=>\@leaves is given, then the set of leaves of these networks will
       be @leaves. If it is given the parameter -numleaves=>$numleaves, then the set of leaves
       will be "l1"..."l$numleaves".

       If the parameter -numhybrids=>$numhybrids is given, then the generated networks will have
       at most $numhybrids hybrid nodes. Note that, necessarily, $numhybrids < $numleaves.

       If the parameter -recurse=>1 is given, then all networks with number of hybrid nodes less
       or equal to $numhybrids will be given; otherwise only those with exactly $numhybrids
       hybrid nodes.

   next_network
        Title   : next_network
        Usage   : my $net=$factory->next_network()
        Function: returns a network
        Returns : Bio::PhyloNetwork
        Args    : none
