implements CoreConnectionPNames

An adaptor for accessing connection parameters in HttpParams.
Note that the implements relation to CoreConnectionPNames is for compatibility with existing application code only. References to the parameter names should use the interface, not this class.

Method Detail

getSoTimeout

public static int getSoTimeout(HttpParams params)
Returns the default socket timeout (SO_TIMEOUT) in milliseconds which is the timeout for waiting for data. A timeout value of zero is interpreted as an infinite timeout. This value is used when no socket timeout is set in the method parameters.

Returns:
timeout in milliseconds

setSoTimeout

public static void setSoTimeout(HttpParams params,
                                int timeout)
Sets the default socket timeout (SO_TIMEOUT) in milliseconds which is the timeout for waiting for data. A timeout value of zero is interpreted as an infinite timeout. This value is used when no socket timeout is set in the method parameters.

Parameters:
timeout - Timeout in milliseconds

getTcpNoDelay

public static boolean getTcpNoDelay(HttpParams params)
Tests if Nagle's algorithm is to be used.

Returns:
true if the Nagle's algorithm is to NOT be used (that is enable TCP_NODELAY), false otherwise.

setTcpNoDelay

public static void setTcpNoDelay(HttpParams params,
                                 boolean value)
Determines whether Nagle's algorithm is to be used. The Nagle's algorithm tries to conserve bandwidth by minimizing the number of segments that are sent. When applications wish to decrease network latency and increase performance, they can disable Nagle's algorithm (that is enable TCP_NODELAY). Data will be sent earlier, at the cost of an increase in bandwidth consumption.

Parameters:
value - true if the Nagle's algorithm is to NOT be used (that is enable TCP_NODELAY), false otherwise.

getSocketBufferSize

public static int getSocketBufferSize(HttpParams params)

setSocketBufferSize

public static void setSocketBufferSize(HttpParams params,
                                       int size)

getLinger

public static int getLinger(HttpParams params)
Returns linger-on-close timeout. Value 0 implies that the option is disabled. Value -1 implies that the JRE default is used.

Returns:
the linger-on-close timeout

setLinger

public static void setLinger(HttpParams params,
                             int value)
Returns linger-on-close timeout. This option disables/enables immediate return from a close() of a TCP Socket. Enabling this option with a non-zero Integer timeout means that a close() will block pending the transmission and acknowledgement of all data written to the peer, at which point the socket is closed gracefully. Value 0 implies that the option is disabled. Value -1 implies that the JRE default is used.

Parameters:
value - the linger-on-close timeout

getConnectionTimeout

public static int getConnectionTimeout(HttpParams params)
Returns the timeout until a connection is etablished. A value of zero means the timeout is not used. The default value is zero.

Returns:
timeout in milliseconds.

setConnectionTimeout

public static void setConnectionTimeout(HttpParams params,
                                        int timeout)
Sets the timeout until a connection is etablished. A value of zero means the timeout is not used. The default value is zero.

Parameters:
timeout - Timeout in milliseconds.

isStaleCheckingEnabled

public static boolean isStaleCheckingEnabled(HttpParams params)
Tests whether stale connection check is to be used. Disabling stale connection check may result in slight performance improvement at the risk of getting an I/O error when executing a request over a connection that has been closed at the server side.

Returns:
true if stale connection check is to be used, false otherwise.

setStaleCheckingEnabled

public static void setStaleCheckingEnabled(HttpParams params,
                                           boolean value)
Defines whether stale connection check is to be used. Disabling stale connection check may result in slight performance improvement at the risk of getting an I/O error when executing a request over a connection that has been closed at the server side.

Parameters:
value - true if stale connection check is to be used, false otherwise.
