Collection Counter


This part counts the number of items in a given collection. The count is sent out not only through the "count_out" terminal, but also through one of the "more_than_zero_out", "zero_out", and "less_than_zero_out" terminals. You can configure the part so that a specific message is sent out through those three terminals. If you do not configure them, the count will be sent out.
