All Implemented Interfaces:

ClientConnectionManager

Deprecated.

(4.3) use BasicHttpClientConnectionManager.

@Contract(threading=SAFE)
@Deprecated
public class BasicClientConnectionManager
extends java.lang.Object
implements ClientConnectionManager

A connection manager for a single connection. This connection manager maintains only one active connection. Even though this class is fully thread-safe it ought to be used by one execution thread only, as only one thread a time can lease the connection at a time.

This connection manager 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.

This connection manager implementation should be used inside an EJB container instead of PoolingClientConnectionManager.

Since:

4.2

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 closeExpiredConnections()

Deprecated.

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.

Specified by:

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:

idletime - the idle time of connections to be closed

tunit - the unit for the idletime
