Constructor Detail

SimpleHttpConnectionManager

public SimpleHttpConnectionManager(boolean alwaysClose)

The connection manager created with this constructor will try to keep the connection open (alive) between consecutive requests if the alwaysClose parameter is set to false. Otherwise the connection manager will always close connections upon release.

Parameters:

alwaysClose - if set true, the connection manager will always close connections upon release.

SimpleHttpConnectionManager

public SimpleHttpConnectionManager()

The connection manager created with this constructor will always try to keep the connection open (alive) between consecutive requests.

Method Detail

getConnection

public HttpConnection getConnection(HostConfiguration hostConfiguration)

Description copied from interface: HttpConnectionManager

Gets an HttpConnection for a given host configuration. If a connection is not available this method will block until one is. The connection manager should be registered with any HttpConnection that is created.

Specified by:

getConnection in interface HttpConnectionManager

Parameters:

hostConfiguration - the host configuration to use to configure the connection

Returns:

an HttpConnection for the given configuration

See Also:

HttpConnectionManager.getConnection(HostConfiguration)

isConnectionStaleCheckingEnabled

public boolean isConnectionStaleCheckingEnabled()

Deprecated. Use HttpConnectionParams.isStaleCheckingEnabled(), HttpConnectionManager.getParams().

Gets the staleCheckingEnabled value to be set on HttpConnections that are created.

Returns:

true if stale checking will be enabled on HttpConections

See Also:

HttpConnection.isStaleCheckingEnabled()

setConnectionStaleCheckingEnabled

public void setConnectionStaleCheckingEnabled(boolean connectionStaleCheckingEnabled)

Deprecated. Use HttpConnectionParams.setStaleCheckingEnabled(boolean), HttpConnectionManager.getParams().

Sets the staleCheckingEnabled value to be set on HttpConnections that are created.

Parameters:

connectionStaleCheckingEnabled - true if stale checking will be enabled on HttpConections

See Also:

HttpConnection.setStaleCheckingEnabled(boolean)

getConnectionWithTimeout

public HttpConnection getConnectionWithTimeout(HostConfiguration hostConfiguration,
                                      long timeout)

This method always returns the same connection object. If the connection is already open, it will be closed and the new host configuration will be applied.

Specified by:

getConnectionWithTimeout in interface HttpConnectionManager

Parameters:

hostConfiguration - The host configuration specifying the connection details.

timeout - this parameter has no effect. The connection is always returned immediately.

Returns:

an HttpConnection for the given configuraiton

Since:

3.0

See Also:

HttpConnection.setHttpConnectionManager(HttpConnectionManager)

getConnection

public HttpConnection getConnection(HostConfiguration hostConfiguration,
                           long timeout)

Deprecated. Use #getConnectionWithTimeout(HostConfiguration, long)

Description copied from interface: HttpConnectionManager

Gets an HttpConnection for a given host configuration. If a connection is not available, this method will block for at most the specified number of milliseconds or until a connection becomes available. The connection manager should be registered with any HttpConnection that is created.

Specified by:

getConnection in interface HttpConnectionManager

Parameters:

hostConfiguration - the host configuration to use to configure the connection

timeout - - the time (in milliseconds) to wait for a connection to become available, 0 to specify an infinite timeout

Returns:

an HttpConnection for the given configuraiton

See Also:

HttpConnectionManager.getConnection(HostConfiguration, long)

releaseConnection

public void releaseConnection(HttpConnection conn)

Description copied from interface: HttpConnectionManager

Releases the given HttpConnection for use by other requests.
