Method Details

withHost

public OnapMsgRouterSubscriber.Builder withHost(String host)

Add a host to the set the publisher can use. If you do not provide a protocol, "http://" is assumed. You may specify "https://" or "http://". If you do not provide a port (e.g. "host:3904"), then 3904 is assumed for http, and 3905 for https. Thus "localhost" is treated as "http://localhost:3904".

Overrides:

withHost in class CommonClientBuilder

Parameters:

host - the host to add to the host set

Returns:

this builder

withHosts

public OnapMsgRouterSubscriber.Builder withHosts(Collection<String> hosts)
