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.
