NAME

       Bio::IdCollectionI - interface for objects with multiple identifiers

SYNOPSIS

           # 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);

DESCRIPTION

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

Implementation Specific Functions

       These functions are the ones that a specific implementation must define.

   id_authorities
        Title   : id_authorities
        Usage   : @array    = $obj->id_authorities()
        Function: Return the authorities which have names for this object.
                  The authorities can then be used to select ids.

        Returns : An array
        Status  : Virtual

   ids
        Title   : ids
        Usage   : @ids    = $obj->ids([$authority1,$authority2...])
        Function: return a list of Bio::IdentifiableI objects, optionally
                  filtered by the list of authorities.

        Returns : A list of Bio::IdentifiableI objects.
        Status  : Virtual
