      • add

        public DomainWildcardMappingBuilder<V> add​(String hostname,
                                           V output)
        Adds a mapping that maps the specified (optionally wildcard) host name to the specified output value. null values are forbidden for both hostnames and values.

        DNS wildcard is supported as hostname. The wildcard will only match one sub-domain deep and only when wildcard is used as the most-left label. For example:

        *.netty.io will match xyz.netty.io but NOT abc.xyz.netty.io

        Parameters:
        hostname - the host name (optionally wildcard)
        output - the output value that will be returned by Mapping.map(Object) when the specified host name matches the specified input host name
