getPublisherBuilder

public org.eclipse.microprofile.reactive.streams.operators.PublisherBuilder<? extends Message<?>> getPublisherBuilder(org.eclipse.microprofile.config.Config config)

Description copied from interface: IncomingConnectorFactory

Creates a channel for the given configuration. The channel's configuration is associated with a specific connector, using the Connector qualifier's parameter indicating a key to which IncomingConnectorFactory to use.

Note that the connection to the transport or broker is generally postponed until the subscription occurs.

Specified by:

getPublisherBuilder in interface IncomingConnectorFactory

Parameters:

config - the configuration, must not be null, must contain the ConnectorFactory.CHANNEL_NAME_ATTRIBUTE attribute.

Returns:

the created PublisherBuilder, will not be null.

getSubscriberBuilder

public org.eclipse.microprofile.reactive.streams.operators.SubscriberBuilder<? extends Message<?>,Void> getSubscriberBuilder(org.eclipse.microprofile.config.Config config)

Description copied from interface: OutgoingConnectorFactory

Creates a channel for the given configuration. The channel's configuration is associated with a specific connector, using the Connector qualifier's parameter indicating a key to which Outgoing to use.

Note that the connection to the transport or broker is generally postponed until the subscription.

Specified by:

getSubscriberBuilder in interface OutgoingConnectorFactory

Parameters:

config - the configuration, never null, must contain the ConnectorFactory.CHANNEL_NAME_ATTRIBUTE attribute.

Returns:

the created SubscriberBuilder, must not be null.
