SyncEnumerator creates an Enumerable object from multiple Enumerable objects and enumerates them synchronously.
Example
require 'generator'
s = SyncEnumerator.new([1,2,3], ['a', 'b', 'c'])
# Yields [1, 'a'], [2, 'b'], and [3,'c']
s.each { |row| puts row.join(', ') }

Class Method Detail
new(*enums)
Creates a new SyncEnumerator which enumerates rows of given Enumerable objects.
Instance Method Detail
each() {|ret| ...}
Enumerates rows of the Enumerable objects.
end?(i = nil)
Returns true if the given nth Enumerable object has reached the end. If no argument is given, returns true if any of the Enumerable objects has reached the end.
length()
Returns the number of enumerated Enumerable objects, i.e. the size of each row.
size()
Returns the number of enumerated Enumerable objects, i.e. the size of each row.
