question: creates a consolidated set of opfitem from item builders and a listof spine item ids . concode_field_sep Map<String,OPFItem> itemsById concode_elem_sep Map<String,OPFItem> itemsByPath concode_elem_sep List<OPFItem> spine concode_elem_sep List<OPFItem> items concode_field_sep List<OPFItem> getItems concode_elem_sep Optional<OPFItem> getItemById concode_elem_sep Optional<OPFItem> getItemByPath concode_elem_sep List<OPFItem> getSpineItems
target: OPFItems function ( Iterable < Builder > arg0 , Iterable < String > arg1 ) { return new OPFItems ( Iterables . transform ( Preconditions . checkNotNull ( arg0 ) , new Function < OPFItem . Builder , OPFItem > ( ) { @ Override public OPFItem apply ( Builder arg2 ) { return arg2 . build ( ) ; } } ) , Preconditions . checkNotNull ( arg1 ) ) ; }
