C++ definition

Connects one packet producer to multiple packet consumers. It can be populated with packets from the connected packet producer. When this occurs, the classifier pushes the packet to one of its connected packet consumers based on the configured packet filters. The first matching expression determines the index of the output gate.

    parameters:
        int defaultGateIndex = default(0); // Default gate index if no matching labels are found
        object packetFilters; // Array of packet filter expressions
