Manually exporting events via a SendConnector

Here we are using Connectors to subscribe to a set of events, convert them to a proprietary format, then send them over some transport:

var connector = new SendConnector.Builder<IPFSystemEvent<?>, String>("eventSendConnector")
        .withTargetTypeConverter(evt -> String.format("{'eventName': '%s', 'createdAt':'%s'}", evt.getName(), evt.getCreatedAt().toString()))
        .withTransportMessageConverter(TransportMessage::new)
        .withConnectorTransport(connectorTransport)
        .build();

eventBus.subscribe(new EventProcessor() {
    @Override
    public Predicate<IPFSystemEvent<?>> predicate() {
        return evt -> evt.getLevel() == EventLevel.ERROR;
    }

    @Override
    public void notify(IPFSystemEvent<?> event) {
        connector.send(event.getMessageAssociation(), event);
    }
});

We first create the connector with:

A way to convert the event to a target type (withTargetTypeConverter) - in this case an example JSON payload
A way to convert the target type into a message to send over transport (withTransportMessageConverter)
A ConnectorTransport - JMS, Kafka and HTTP are supported, but you can write your own too
