Method Detail

isSecure

boolean isSecure()

Deprecated.

Indicates whether this connection is secure. The return value is well-defined only while the connection is open. It may change even while the connection is open.

Specified by:

isSecure in interface HttpRoutedConnection

Returns:

true if this connection is secure, false otherwise

getRoute

HttpRoute getRoute()

Deprecated.

Obtains the current route of this connection.

Specified by:

getRoute in interface HttpRoutedConnection

Returns:

the route established so far, or null if not connected

getSSLSession

javax.net.ssl.SSLSession getSSLSession()

Deprecated.

Obtains the SSL session of the underlying connection, if any. If this connection is open, and the underlying socket is an SSLSocket, the SSL session of that socket is obtained. This is a potentially blocking operation.
Note: Whether the underlying socket is an SSL socket can not necessarily be determined via isSecure(). Plain sockets may be considered secure, for example if they are connected to a known host in the same network segment. On the other hand, SSL sockets may be considered insecure, for example depending on the chosen cipher suite.

Specified by:

getSSLSession in interface HttpRoutedConnection

Specified by:

getSSLSession in interface ManagedHttpClientConnection

Returns:

the underlying SSL session if available, null otherwise

open

void open(HttpRoute route,
          HttpContext context,
          HttpParams params)
   throws java.io.IOException

Deprecated.

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:

java.io.IOException - in case of a problem

tunnelTarget

void tunnelTarget(boolean secure,
                  HttpParams params)
           throws java.io.IOException

Deprecated.

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:

java.io.IOException - in case of a problem

tunnelProxy

void tunnelProxy(HttpHost next,
                 boolean secure,
                 HttpParams params)
          throws java.io.IOException

Deprecated.

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 tunnelTarget(boolean, cz.msebera.android.httpclient.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 tunnelTarget(boolean, cz.msebera.android.httpclient.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:

java.io.IOException - in case of a problem

layerProtocol

void layerProtocol(HttpContext context,
                   HttpParams params)
            throws java.io.IOException

Deprecated.

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:

java.io.IOException - in case of a problem

markReusable

void markReusable()

Deprecated.

Marks this connection as being in a reusable communication state. The checkpoints for reuseable communication states (in the absence of pipelining) are before sending a request and after receiving the response in its entirety. The connection will automatically clear the checkpoint when used for communication. A call to this method indicates that the next checkpoint has been reached.
A reusable communication state is necessary but not sufficient for the connection to be reused. A route mismatch, the connection being closed, or other circumstances might prevent reuse.

unmarkReusable

void unmarkReusable()

Deprecated.

Marks this connection as not being in a reusable state. This can be used immediately before releasing this connection to prevent its reuse. Reasons for preventing reuse include error conditions and the evaluation of a reuse strategy.
Note: It is not necessary to call here before writing to or reading from this connection. Communication attempts will automatically unmark the state as non-reusable. It can then be switched back using markReusable.

isMarkedReusable

boolean isMarkedReusable()

Deprecated.

Indicates whether this connection is in a reusable communication state. See markReusable and unmarkReusable for details.

Returns:

true if this connection is marked as being in a reusable communication state, false otherwise

setState

void setState(java.lang.Object state)

Deprecated.

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

getState

java.lang.Object getState()

Deprecated.

Returns the state object associated with this connection.

Returns:

The state object

setIdleDuration

void setIdleDuration(long duration,
                     java.util.concurrent.TimeUnit unit)

Deprecated.

Sets the duration that this connection can remain idle before it is reused. The connection should not be used again if this time elapses. The idle duration must be reset after each request sent over this connection. The elapsed time starts counting when the connection is released, which is typically after the headers (and any response body, if present) is fully consumed.
