public class Merge extends DETransformer
This actor has an input port (a multiport) and an output port (a single port). The types of the ports are undeclared and will be resolved by the type resolution mechanism, with the constraint that the output type must be greater than or equal to the input type.
There is a boolean parameter discardEvents associated with this actor, which decides how to handle simultaneously available inputs. Each time this actor fires, it reads the first available tokens from an input channel and sends them to the output port. If the discardEvents parameter is configured to true, then this actor discards all the remaining inputs in the rest of channels. Otherwise, this actor requests refirings at the current time until no more events are left in the channels. By default, the discardEvents parameter is false.

void |
fire()
Read the first available tokens from an input channel and
send them to the output port.
|
boolean |
prefire()
Return false if there was a firing at the current time and
microstep that produced an output token and there are more
tokens on other channels that are waiting to be produced at
the same time but future microsteps.
