nl_tokens: Create a DS . ManyArray for a type and list of record references and index the ManyArray under each reference . This allows us to efficiently remove records from ManyArray s when they are deleted .
pl_tokens: function ( type , records ) { var manyArray = DS . ManyArray . create ( { type : <mask> , content : records , store : this . store } ) ; forEach ( records , function ( record ) { var arrays = this . recordArraysForRecord ( record ) ; arrays . add ( manyArray ) ; } , this ) ; return manyArray ; }
