NAME ^

Bio::Tree::AlleleNode - A Node with Alleles attached

SYNOPSIS ^

  use Bio::Tree::AlleleNode;

DESCRIPTION ^

AlleleNodes are basic Bio::Tree::Nodes with the added ability to add Genotypes alleles as defined by the Bio::PopGen::IndividualI interface. Genotypes are defined by the Bio::PopGen::GenotypeI interface, you will probably want to use the Bio::PopGen::Genotype implementation.

This is implemented via containment to avoid multiple inheritance problems. Their is a Bio::PopGen::Individual object which handles the Bio::PopGen::IndividualI interface, and is accessible via the Bio::Tree::AlleleNode::individual method.

FEEDBACK ^

Mailing Lists

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing list. Your participation is much appreciated.

Support

Please direct usage questions or support issues to the mailing list:

HISTORY ^

This module was re-written to be a combination of Bio::PopGen::Individual and Bio::Tree::Node primarily for use in Bio::PopGen::Simulation::Coalescent simulations.

 Function: Adds a descendent to a node
 Returns : number of current descendents for this node
 Args    : Bio::Node::NodeI
           boolean flag, true if you want to ignore the fact that you are

           location reference in this implementation).  default is false and 
           will throw an error if you try and overwrite an existing node.

each_Descendent

"A name can be any string of printable characters except blanks, colons, semicolons, parentheses, and square brackets. Because you may want to include a blank in a name, it is assumed that an underscore character ("_") stands for a blank; any of these in a name will be converted to a blank when it is read in."

internal_id

 Title   : internal_id
