NAME

       Bio::DBLinkContainerI - Abstract interface for any object wanting to use
                               database cross references

SYNOPSIS

           # get an objects containing database cross reference

               foreach $obj ( @objs ) {
                       if( $obj->isa('Bio::DBLinkContainerI') ) {
                               foreach $dblink ( $obj->each_DBLink() ) {
                                       # do stuff
                               }

               }

DESCRIPTION

       This interface defines the functions one can expect for any object wanting to use database
       cross-references. This class does not actually provide any implementation, it just
       provides the definitions of what methods one can call.

       The database cross-references are implemented as Bio::Annotation::DBLink objects.
