All Implemented Interfaces:

Closeable, AutoCloseable, ConnectionReleaseTrigger, HttpRoutedConnection, ManagedClientConnection, ManagedHttpClientConnection, org.apache.http.HttpClientConnection, org.apache.http.HttpConnection, org.apache.http.HttpInetConnection, org.apache.http.protocol.HttpContext

@Deprecated
public abstract class AbstractPooledConnAdapter
extends AbstractClientConnAdapter

Abstract adapter from pool entries to managed client connections. The connection in the pool entry is used to initialize the base class. In addition, methods to establish a route are delegated to the pool entry. shutdown and close will clear the tracked route in the pool entry and call the respective method of the wrapped connection.

Since:

4.0

Field Detail

poolEntry

protected volatile AbstractPoolEntry poolEntry

Deprecated.

The wrapped pool entry.

Constructor Detail

AbstractPooledConnAdapter

protected AbstractPooledConnAdapter(ClientConnectionManager manager,
                         AbstractPoolEntry entry)

Deprecated.

Creates a new connection adapter.

Parameters:

manager - the connection manager

entry - the pool entry for the connection being wrapped

Method Detail

getId

public String getId()

Deprecated.

Description copied from interface: ManagedHttpClientConnection

Returns connection ID which is expected to be unique for the life span of the connection manager.

getPoolEntry

@Deprecated
protected AbstractPoolEntry getPoolEntry()

Deprecated. (4.0.1)

Obtains the pool entry.

Returns:

the pool entry, or null if detached

assertValid

protected void assertValid(AbstractPoolEntry entry)

Deprecated.

Asserts that there is a valid pool entry.

Throws:

ConnectionShutdownException - if there is no pool entry or connection has been aborted

See Also:

AbstractClientConnAdapter.assertValid(OperatedClientConnection)

assertAttached

@Deprecated
protected final void assertAttached()

Deprecated. (4.1) use assertValid(AbstractPoolEntry)

detach

protected void detach()

Deprecated.

Detaches this adapter from the wrapped connection. This adapter becomes useless.

Overrides:

detach in class AbstractClientConnAdapter

getRoute

public HttpRoute getRoute()

Deprecated.

Description copied from interface: ManagedClientConnection

Obtains the current route of this connection.

Returns:

the route established so far, or null if not connected

open

public void open(HttpRoute route,
        org.apache.http.protocol.HttpContext context,
        org.apache.http.params.HttpParams params)
          throws IOException

Deprecated.

Description copied from interface: ManagedClientConnection

Opens this connection according to the given route.

Parameters:

route - the route along which to open. It will be opened to the first proxy if present, or directly to the target.

context - the context for opening this connection

params - the parameters for opening this connection

Throws:

IOException - in case of a problem

tunnelTarget

public void tunnelTarget(boolean secure,
                org.apache.http.params.HttpParams params)
                  throws IOException

Deprecated.

Description copied from interface: ManagedClientConnection

Indicates that a tunnel to the target has been established. The route is the one previously passed to open. Subsequently, layerProtocol can be called to layer the TLS/SSL protocol on top of the tunnelled connection.

Note: In HttpClient 3, a call to the corresponding method would automatically trigger the layering of the TLS/SSL protocol. This is not the case anymore, you can establish a tunnel without layering a new protocol over the connection.

Parameters:

secure - true if the tunnel should be considered secure, false otherwise

params - the parameters for tunnelling this connection

Throws:

IOException - in case of a problem

tunnelProxy

public void tunnelProxy(org.apache.http.HttpHost next,
               boolean secure,
               org.apache.http.params.HttpParams params)
                 throws IOException

Deprecated.

Description copied from interface: ManagedClientConnection

Indicates that a tunnel to an intermediate proxy has been established. This is used exclusively for so-called proxy chains, where a request has to pass through multiple proxies before reaching the target. In that case, all proxies but the last need to be tunnelled when establishing the connection. Tunnelling of the last proxy to the target is optional and would be indicated via ManagedClientConnection.tunnelTarget(boolean, org.apache.http.params.HttpParams).

Parameters:

next - the proxy to which the tunnel was established. This is not the proxy through which the tunnel was established, but the new end point of the tunnel. The tunnel does not yet reach to the target, use ManagedClientConnection.tunnelTarget(boolean, org.apache.http.params.HttpParams) to indicate an end-to-end tunnel.

secure - true if the connection should be considered secure, false otherwise

params - the parameters for tunnelling this connection

Throws:

IOException - in case of a problem

layerProtocol

public void layerProtocol(org.apache.http.protocol.HttpContext context,
                 org.apache.http.params.HttpParams params)
                   throws IOException

Deprecated.

Description copied from interface: ManagedClientConnection

Layers a new protocol on top of a tunnelled connection. This is typically used to create a TLS/SSL connection through a proxy. The route is the one previously passed to open. It is not guaranteed that the layered connection is secure.

Parameters:

context - the context for layering on top of this connection

params - the parameters for layering on top of this connection

Throws:

IOException - in case of a problem

close

public void close()
           throws IOException

Deprecated.

Throws:

IOException

shutdown

public void shutdown()
              throws IOException

Deprecated.

Throws:

IOException

getState

public Object getState()

Deprecated.

Description copied from interface: ManagedClientConnection

Returns the state object associated with this connection.

Returns:

The state object

setState

public void setState(Object state)

Deprecated.

Description copied from interface: ManagedClientConnection

Assigns a state object to this connection. Connection managers may make use of the connection state when allocating persistent connections.

Parameters:

state - The state object
