Class PoolingClientConnectionManager

  • All Implemented Interfaces:
    ClientConnectionManager, org.apache.http.pool.ConnPoolControl<HttpRoute>

    @Deprecated
    @Contract(threading=SAFE_CONDITIONAL)
    public class PoolingClientConnectionManager
    extends java.lang.Object
    implements ClientConnectionManager, org.apache.http.pool.ConnPoolControl<HttpRoute>
    Deprecated.
    Manages a pool of OperatedClientConnection and is able to service connection requests from multiple execution threads. Connections are pooled on a per route basis. A request for a route which already the manager has persistent connections for available in the pool will be services by leasing a connection from the pool rather than creating a brand new connection.

    PoolingConnectionManager maintains a maximum limit of connection on a per route basis and in total. Per default this implementation will create no more than than 2 concurrent connections per given route and no more 20 connections in total. For many real-world applications these limits may prove too constraining, especially if they use HTTP as a transport protocol for their services. Connection limits, however, can be adjusted using HTTP parameters.

      • createConnectionOperator

        protected ClientConnectionOperator createConnectionOperator​(SchemeRegistry schreg)
        Deprecated.
        Hook for creating the connection operator. It is called by the constructor. Derived classes can override this method to change the instantiation of the operator. The default implementation here instantiates DefaultClientConnectionOperator.
        Parameters:
        schreg - the scheme registry.
        Returns:
        the connection operator to use
      • releaseConnection

        public void releaseConnection​(ManagedClientConnection conn,
                                      long keepalive,
                                      java.util.concurrent.TimeUnit tunit)
        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
        keepalive - the duration of time this connection is valid for reuse
        tunit - the unit of time validDuration is measured in

        public void shutdown()
        Deprecated.
        Description copied from interface: ClientConnectionManager
        Shuts down this connection manager and releases allocated resources. This includes closing all connections, whether they are currently used or not.

        Deprecated.
        Description copied from interface: ClientConnectionManager
        Closes idle connections in the pool. Open connections in the pool that have not been used for the timespan given by the argument will be closed. Currently allocated connections are not subject to this method. Times will be checked with milliseconds precision All expired connections will also be closed.
        Specified by:
        closeIdleConnections in interface ClientConnectionManager
        Parameters:
        idleTimeout - the idle time of connections to be closed
        tunit - the unit for the idletime

        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.
