e.next_values รข array
Instance Public methods
Returns the next object as an array in the enumerator, and move the internal position forward. When the position reached at the end, StopIteration is raised.
This method can be used to distinguish yield and yield
nil.
Example
o = Object.new def o.each yield yield 1 yield 1, 2 yield nil yield [1, 2] end e = o.to_enum p e.next_values p e.next_values p e.next_values p e.next_values p e.next_values e = o.to_enum p e.next p e.next p e.next p e.next p e.next ## yield args next_values next # yield [] nil # yield 1 [1] 1 # yield 1, 2 [1, 2] [1, 2] # yield nil [nil] nil # yield [1, 2] [[1, 2]] [1, 2]
Note that next_values does not affect other non-external
enumeration methods unless underlying iteration method itself has
side-effect, e.g. IO#each_line.
