Overview

returned from adding (<<) an item to a batch in a batch block: Neoid.batch { |batch| (batch << [:neography_command, param]).is_a?(SingleResultPromiseProxy) } so a ‘.then` can be chained: Neoid.batch { |batch| (batch << [:neography_command, param]).then { |result| puts result } } the `then` is called once the batch is flushed with the result of the single job in the batch it proxies all methods to the result, so in case it is returned (like in Neoid.execute_script_or_add_to_batch) the result of the method will be proxied to the result from the batch.
