Class ThreadSafeClientConnManager

java.lang.Object
org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager
All Implemented Interfaces:
ClientConnectionManager
@Contract(threading=SAFE_CONDITIONAL) @Deprecated public class ThreadSafeClientConnManager extends 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

      connTTL - max connection lifetime, <=0 implies "infinity"
      connTTLTimeUnit - TimeUnit of connTTL
      connPerRoute - mapping of maximum connections per route, provided as a dependency so it can be managed externally, e.g. for dynamic connection pool size management.

    • getSchemeRegistry

      public SchemeRegistry getSchemeRegistry()
      Deprecated.
      Description copied from interface: ClientConnectionManager
      Obtains the scheme registry used by this manager.
      Specified by:
      getSchemeRegistry in interface ClientConnectionManager
      Returns:
      the scheme registry, never null

    • requestConnection

      public ClientConnectionRequest requestConnection(HttpRoute route, Object state)
      Deprecated.
      Description copied from interface: ClientConnectionManager
      Returns a new ClientConnectionRequest, from which a ManagedClientConnection can be obtained or the request can be aborted.
      Specified by:
      requestConnection in interface ClientConnectionManager

    • releaseConnection

      public void releaseConnection(ManagedClientConnection conn, long validDuration, 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

    • 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

      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

      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
      timeUnit - the unit for the idletime
