Bio::DescribableI - interface for objects with human readable names and descriptions


    # to test this is a describable object

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

    # accessors

    $name = $obj->display_name();
    $desc = $obj->description();


This interface describes methods expected on describable objects, ie ones which have human displayable names and descriptions

Implementation Specific Functions

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


 Title   : display_name
 Usage   : $string    = $obj->display_name()
 Function: A string which is what should be displayed to the user
           the string should have no spaces (ideally, though a cautious
           user of this interface would not assumme this) and should be
           less than thirty characters (though again, double checking 
           this is a good idea)
 Returns : A scalar
 Status  : Virtual


 Title   : description
 Usage   : $string    = $obj->description()
 Function: A text string suitable for displaying to the user a 
           description. This string is likely to have spaces, but
           should not have any newlines or formatting - just plain
           text. The string should not be greater than 255 characters
           and clients can feel justified at truncating strings at 255
           characters for the purposes of display
 Returns : A scalar
 Status  : Virtual
