Package com.yahoo.vespa.config

Class JRTConnectionPool

java.lang.Object

com.yahoo.vespa.config.JRTConnectionPool

All Implemented Interfaces:

ConnectionPool, java.lang.AutoCloseable

public class JRTConnectionPool
extends java.lang.Object
implements ConnectionPool

A pool of JRT connections to a config source (either a config server or a config proxy). The current connection is chosen randomly when calling {#link switchConnection()} (it will continue to use the same connection if there is only one source). The current connection is available with getCurrent(). When calling setError(Connection, int), switchConnection() will always be called.
