Class SmackConfiguration

java.lang.Object

org.jivesoftware.smack.SmackConfiguration

public final class SmackConfiguration
extends Object

Represents the configuration of Smack. The configuration is used for:

• Initializing classes by loading them at start-up.
• Getting the current Smack version.
• Getting and setting global library behavior, such as the period of time to wait for replies to packets from the server. Note: setting these values via the API will override settings in the configuration file.

Configuration settings are stored in org.jivesoftware.smack/smack-config.xml.

Field Detail

DEBUG

public static boolean DEBUG

Value that indicates whether debugging is enabled. When enabled, a debug window will apear for each new connection that will contain the following information:

• Client Traffic -- raw XML traffic generated by Smack and sent to the server.
• Server Traffic -- raw XML traffic sent by the server to the client.
• Interpreted Packets -- shows XML packets from the server as parsed by Smack.

Debugging can be enabled by setting this field to true, or by setting the Java system property smack.debugEnabled to true. The system property can be set on the command line such as "java SomeApp -Dsmack.debugEnabled=true".

Constructor Detail

SmackConfiguration

public SmackConfiguration()

Method Detail

getVersion

public static String getVersion()

Returns the Smack version information, eg "1.3.0".

Returns:

the Smack version information.

getDefaultPacketReplyTimeout

public static int getDefaultPacketReplyTimeout()

Returns the number of milliseconds to wait for a response from the server. The default value is 5000 ms.

Returns:

the milliseconds to wait for a response from the server

setDefaultPacketReplyTimeout

public static void setDefaultPacketReplyTimeout(int timeout)

Sets the number of milliseconds to wait for a response from the server.

Parameters:

timeout - the milliseconds to wait for a response from the server

getPacketCollectorSize

public static int getPacketCollectorSize()

Gets the default max size of a stanza(/packet) collector before it will delete the older packets.

Returns:

The number of packets to queue before deleting older packets.

setPacketCollectorSize

public static void setPacketCollectorSize(int collectorSize)

Sets the default max size of a stanza(/packet) collector before it will delete the older packets.

Parameters:

collectorSize - the number of packets to queue before deleting older packets.

addSaslMech

public static void addSaslMech(String mech)

Add a SASL mechanism to the list to be used.

Parameters:

mech - the SASL mechanism to be added

addSaslMechs

public static void addSaslMechs(Collection<String> mechs)

Add a Collection of SASL mechanisms to the list to be used.

Parameters:

mechs - the Collection of SASL mechanisms to be added

setDebuggerFactory

public static void setDebuggerFactory(SmackDebuggerFactory debuggerFactory)

Sets Smack debugger factory.

Parameters:

debuggerFactory - new debugger factory implementation to be used by Smack

getDebuggerFactory

public static SmackDebuggerFactory getDebuggerFactory()

Returns:

a debugger factory or null

createDebugger

public static SmackDebugger createDebugger(XMPPConnection connection,
                                           Writer writer,
                                           Reader reader)

Creates new debugger instance with given arguments as parameters. May return null if no DebuggerFactory is set or if the factory did not produce a debugger.

Parameters:

connection -

writer -

reader -

Returns:

a new debugger or null

removeSaslMech

public static void removeSaslMech(String mech)

Remove a SASL mechanism from the list to be used.

Parameters:

mech - the SASL mechanism to be removed

removeSaslMechs

public static void removeSaslMechs(Collection<String> mechs)

Remove a Collection of SASL mechanisms to the list to be used.

Parameters:

mechs - the Collection of SASL mechanisms to be removed

getSaslMechs

public static List<String> getSaslMechs()

Returns the list of SASL mechanisms to be used. If a SASL mechanism is listed here it does not guarantee it will be used. The server may not support it, or it may not be implemented.

Returns:

the list of SASL mechanisms to be used.

setDefaultParsingExceptionCallback

public static ParsingExceptionCallback getDefaultParsingExceptionCallback()

Returns the default parsing exception callback

Returns:

the default parsing exception callback

setDefaultHostnameVerifier

public static void setDefaultHostnameVerifier(HostnameVerifier verifier)

XMPP connections are able to overwrite this settings by supplying a HostnameVerifier in their ConnecitonConfiguration with ConnectionConfiguration.Builder.setHostnameVerifier(HostnameVerifier).

addDisabledSmackClass

public static void addDisabledSmackClass(Class<?> clz)

Convenience method for addDisabledSmackClass(String).

Parameters:

clz - the Smack class to disable
