NAME

       Bio::Map::PositionHandlerI - A Position Handler Interface

SYNOPSIS

           # do not use this module directly
           # See Bio::Map::PositionHandler for an example of
           # implementation.

DESCRIPTION

       This interface describes the basic methods required for Position Handlers. A Position
       Handler copes with the coordination of different Bio::Map::EntityI objects, adding and
       removing them from each other and knowning who belongs to who. These relationships between
       objects are based around shared Positions, hence PositionHandler.

       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:

       rather than to the module maintainer directly. Many experienced and reponsive experts will
       be able look at the problem and quickly address it. Please include a thorough description
       of the problem with code and data examples if at all possible.
