Example 1 with IncomingConnectorFactory

use of org.eclipse.microprofile.reactive.messaging.spi.IncomingConnectorFactory in project helidon by oracle.

the class ChannelRouter method addOutgoingConnector.

private void addOutgoingConnector(Bean<?> bean) {
    IncomingConnectorFactory incomingConnectorFactory = lookup(bean, beanManager);
    String connectorName = bean.getBeanClass().getAnnotation(Connector.class).value();

}

Example 2 with IncomingConnectorFactory

use of org.eclipse.microprofile.reactive.messaging.spi.IncomingConnectorFactory in project smallrye-reactive-messaging by smallrye.

the class RabbitMQConnector method getPublisherBuilder.

/**
 * Creates a <em>channel</em> for the given configuration. The channel's configuration is associated with a
 * specific {@code connector}, using the {@link Connector} qualifier's parameter indicating a key to
 * which {@link IncomingConnectorFactory} to use.
 *
 * <p>
 * Note that the connection to the <em>transport</em> or <em>broker</em> is generally postponed until the
 * subscription occurs.
 *
 * @param config the configuration, must not be {@code null}, must contain the {@link #CHANNEL_NAME_ATTRIBUTE}
 *        attribute.
 * @return the created {@link PublisherBuilder}, will not be {@code null}.
 * @throws IllegalArgumentException if the configuration is invalid.
 * @throws NoSuchElementException if the configuration does not contain an expected attribute.
