Class ThreadSafeClientConnManager

  • All Implemented Interfaces:
    ClientConnectionManager
    @Contract(threading=SAFE_CONDITIONAL)
@Deprecated
public class ThreadSafeClientConnManager
extends java.lang.Object
implements ClientConnectionManager
    Deprecated.
    (4.2) use PoolingHttpClientConnectionManager
    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.

    ThreadSafeClientConnManager 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.

    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
        See Also:

      • shutdown

        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.
        Specified by:
        shutdown in interface ClientConnectionManager

      • getConnectionsInPool

        public int getConnectionsInPool​(HttpRoute route)
        Deprecated.
        Gets the total number of pooled connections for the given route. This is the total number of connections that have been created and are still in use by this connection manager for the route. This value will not exceed the maximum number of connections per host.
        Parameters:
        route - the route in question
        Returns:
        the total number of pooled connections for that route

      • getConnectionsInPool

        public int getConnectionsInPool()
        Deprecated.
        Gets the total number of pooled connections. This is the total number of connections that have been created and are still in use by this connection manager. This value will not exceed the maximum number of connections in total.
        Returns:
        the total number of pooled connections

        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
