Bio::IdCollectionI - interface for objects with multiple identifiers


    # to test this is an identifiable collection object

    $obj->isa("Bio::IdCollectionI") ||
      $obj->throw("$obj does not implement the Bio::IdCollectionI interface");

    # accessors
    @authorities = $obj->id_authorities();
    @ids         = $obj->ids();
    $id          = $obj->ids($authority);


This interface describes methods expected on objects that have multiple identifiers, each of which is controlled by a different authority.
