Class PoolingClientConnectionManager

java.lang.Object

cz.msebera.android.httpclient.impl.conn.PoolingClientConnectionManager

All Implemented Interfaces:

ClientConnectionManager, ConnPoolControl<HttpRoute>

Deprecated.

(4.3) use PoolingHttpClientConnectionManager.

@Deprecated
 @ThreadSafe
public class PoolingClientConnectionManager
extends java.lang.Object
implements ClientConnectionManager, ConnPoolControl<HttpRoute>

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.

PoolingConnectionManager 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.

4.2

Method Detail

finalize

protected void finalize()
                 throws java.lang.Throwable

Deprecated.

Overrides:

finalize in class java.lang.Object

Throws:

java.lang.Throwable

createConnectionOperator

protected ClientConnectionOperator createConnectionOperator(SchemeRegistry schreg)

Deprecated.

Hook for creating the connection operator. It is called by the constructor. Derived classes can override this method to change the instantiation of the operator. The default implementation here instantiates DefaultClientConnectionOperator.

Parameters:

schreg - the scheme registry.

Returns:

the connection operator to use

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,
                                                 java.lang.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 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
