Class SingleClientConnManager

  • All Implemented Interfaces:
    ClientConnectionManager
    @Contract(threading=SAFE)
@Deprecated
public class SingleClientConnManager
extends java.lang.Object
implements ClientConnectionManager
    Deprecated.
    (4.2) use BasicClientConnectionManager
    A connection manager for a single connection. This connection manager maintains only one active connection at a time. Even though this class is thread-safe it ought to be used by one execution thread only.

    SingleClientConnManager will make an effort to reuse the connection for subsequent requests with the same route. It will, however, close the existing connection and open it for the given route, if the route of the persistent connection does not match that of the connection request. If the connection has been already been allocated IllegalStateException is thrown.

    Since:
    4.0

      • releaseConnection

        public void releaseConnection​(ManagedClientConnection conn,
                              long validDuration,
                              java.util.concurrent.TimeUnit timeUnit)
        Deprecated.
        Description copied from interface: ClientConnectionManager
        Releases a connection for use by others. You may optionally specify how long the connection is valid to be reused. Values <= 0 are considered to be valid forever. If the connection is not marked as reusable, the connection will not be reused regardless of the valid duration. If the connection has been released before, the call will be ignored.
        Specified by:
        releaseConnection in interface ClientConnectionManager
        Parameters:
        conn - the connection to release
        validDuration - the duration of time this connection is valid for reuse
        timeUnit - the unit of time validDuration is measured in

        Description copied from interface: ClientConnectionManager
        Closes all expired connections in the pool. Open connections in the pool that have not been used for the timespan defined when the connection was released will be closed. Currently allocated connections are not subject to this method. Times will be checked with milliseconds precision.
