Class BasicClientConnectionManager

java.lang.Object

org.apache.http.impl.conn.BasicClientConnectionManager

All Implemented Interfaces:

ClientConnectionManager

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

Deprecated.

(4.3) use BasicHttpClientConnectionManager.

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

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

Deprecated.

releaseConnection

public void releaseConnection(ManagedClientConnection conn,
 long keepalive,
 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

keepalive - the duration of time this connection is valid for reuse

timeUnit - the unit of time validDuration is measured in

Specified by:

closeIdleConnections in interface ClientConnectionManager

Parameters:

idletime - the idle time of connections to be closed

timeUnit - the unit for the idletime
