Class BasicHttpClientConnectionManager

java.lang.Object

org.apache.http.impl.conn.BasicHttpClientConnectionManager

All Implemented Interfaces:

Closeable, AutoCloseable, HttpClientConnectionManager

@ThreadSafe
public class BasicHttpClientConnectionManager
extends Object
implements HttpClientConnectionManager, Closeable

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 PoolingHttpClientConnectionManager.

Since:

4.3

requestConnection

public final ConnectionRequest requestConnection(HttpRoute route,
                                  Object state)

Description copied from interface: HttpClientConnectionManager

Returns a new ClientConnectionRequest, from which a HttpClientConnection can be obtained or the request can be aborted.

Specified by:

requestConnection in interface HttpClientConnectionManager

releaseConnection

public void releaseConnection(HttpClientConnection conn,
                     Object state,
                     long keepalive,
                     TimeUnit tunit)

Description copied from interface: HttpClientConnectionManager

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 HttpClientConnectionManager

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

closeExpiredConnections

public void closeExpiredConnections()

Description copied from interface: HttpClientConnectionManager

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:

closeExpiredConnections in interface HttpClientConnectionManager

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 HttpClientConnectionManager

Parameters:

idletime - the idle time of connections to be closed

tunit - the unit for the idletime

shutdown

public void shutdown()

Description copied from interface: HttpClientConnectionManager

Shuts down this connection manager and releases allocated resources. This includes closing all connections, whether they are currently used or not.
