Package com.yahoo.vespa.config

Class JRTConnectionPool

java.lang.Object

com.yahoo.vespa.config.JRTConnectionPool

All Implemented Interfaces:

ConnectionPool

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 #setNewCurrentConnection} (since the connection is chosen randomly, it might end up using the same connection again, and it will always do so if there is only one source). The current connection is available with getCurrent(). When calling setError(Connection, int), {#link #setNewCurrentConnection} will always be called.
