Example 1 with CoordinationType

use of org.lflang.TargetProperty.CoordinationType in project lingua-franca by lf-lang.

the class FedASTUtils method addNetworkSenderReaction.

/**
 * Add a network sender reaction for a given input port 'source' to
 * source's parent reactor. This reaction will react to the 'source'
 * and then send a message on the network destined for the destinationFederate.
 *
 * @note Used in federated execution
 *
 * @param source The source port instance.
 * @param destination The destination port instance.
 * @param connection The network connection.
 * @param sourceFederate The source federate.
 * @param leftBankIndex The left bank index or -1 if the left reactor is not in a bank.
 * @param leftChannelIndex The left channel index or -1 if the left port is not a multiport.
 * @param destinationFederate The destination federate.
 * @param generator The GeneratorBase instance used to perform some target-specific actions
 * @param coordination One of CoordinationType.DECENTRALIZED or CoordinationType.CENTRALIZED.
 * @param serializer The serializer used on the connection
