question: private void addObjectsToBuilder ( @ NotNull StringBuilder builder , @ NotNull List < String > objects , @ NotNull ObjectTypes type ) { Preconditions . checkArgument ( objects . size ( ) >= 1 ) ; for ( String s : objects ) { if ( objects . indexOf ( s ) != 0 ) { builder . append ( " , " ) ; } builder . append ( encapsulateObject ( s , type ) ) ; } }
target:  Method adds a list of objects to the builder: puts commas between the literal and encapsulates the objects with " or <  depending on the boolean literal. Note objects cannot be null and must at least contain one value.
