Examples of org.apache.hedwig.util.HedwigSocketAddress

org.apache.hedwig.util.HedwigSocketAddress
This is a data wrapper class that is basically an InetSocketAddress with one extra piece of information for the SSL port (optional). This is used by Hedwig so we can encapsulate both regular and SSL port information in one data structure. Hedwig hub servers can be configured to listen on the standard regular port and additionally on an optional SSL port. The String representation of a HedwigSocketAddress is: ::
