Package com.yahoo.vespa.model
Class ConfigProxy
- All Implemented Interfaces:
com.yahoo.config.ConfigInstance.Producer
,ConfigProducer
,NetworkPortRequestor
,Service
,Serializable
There is one config proxy running on each Vespa host, and one instance of
this class is therefore created by each instance of class
Host
.
NOTE: The Config proxy is not started by the config system, and
does not receive any config. It's included here so we know what host
it runs on, and to give an error message if another service tries
to reserve the port it is using.- Author:
