ClientConnectionManager
@Contract(threading=SAFE) @Deprecated public class BasicClientConnectionManager extends java.lang.Object implements ClientConnectionManager
Deprecated.(4.3) useBasicHttpClientConnectionManager
.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 allocatedIllegalStateException
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 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 interfaceClientConnectionManager
- Parameters:
conn
- the connection to releasekeepalive
- the duration of time this connection is valid for reusetimeUnit
- the unit of time validDuration is measured in- See Also:

closeExpiredConnections
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:
closeExpiredConnections
in interfaceClientConnectionManager
-
closeIdleConnections
public void closeIdleConnections(long idletime, java.util.concurrent.TimeUnit timeUnit)
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 interfaceClientConnectionManager
- Parameters:
idletime
- the idle time of connections to be closedtimeUnit
- the unit for theidletime
- 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:
