    • Field Detail

      • DEFAULT

        static final NodeValueCodec DEFAULT
        Default NodeValueCodec implementation which assumes zNode value is a comma-separated string. Each element of the zNode value represents an endpoint whose format is <host>[:<port_number>[:weight]], such as:
        • "foo.com" - default port number, default weight (1000)
        • "bar.com:8080 - port number 8080, default weight (1000)
        • "10.0.2.15:0:500 - default port number, weight 500
        • "192.168.1.2:8443:700 - port number 8443, weight 700
        the segment and field delimiter can be specified, default will be "," and ":" Note that the port number must be specified when you want to specify the weight.
