Class ConnectionConfiguration.ConnectionConfigurationBuilder<B extends ConnectionConfiguration.ConnectionConfigurationBuilder<B,C>,C extends ConnectionConfiguration>

java.lang.Object

org.jivesoftware.smack.ConnectionConfiguration.ConnectionConfigurationBuilder<B,C>

Type Parameters:

B - the builder type parameter.

C - the resulting connection configuration type parameter.

Enclosing class:

ConnectionConfiguration

public abstract static class ConnectionConfiguration.ConnectionConfigurationBuilder<B extends ConnectionConfiguration.ConnectionConfigurationBuilder<B,C>,C extends ConnectionConfiguration>
extends java.lang.Object

A builder for XMPP connection configurations.

This is an abstract class that uses the builder design pattern and the "getThis() trick" to recover the type of the builder in a class hierarchies with a self-referential generic supertype. Otherwise chaining of build instructions from the superclasses followed by build instructions of a sublcass would not be possible, because the superclass build instructions would return the builder of the superclass and not the one of the subclass. You can read more about it a Angelika Langer's Generics FAQ, especially the entry What is the "getThis()" trick?.

Method Detail

setUsernameAndPassword

public B setUsernameAndPassword(java.lang.String username,
                       java.lang.String password)

Set the XMPP entities username and password.

The username is the localpart of the entities JID, e.g. localpart@example.org. In order to create an anonymous connection, call makeAnonymous() instead.

Parameters:

username -

password -

Returns:

a reference to this builder.

makeAnonymous

public B makeAnonymous()

Create a configuration for a anonymous XMPP connection.

Anonyous connections don't provide a username or other authentification credentials like a password. Instead the XMPP server, if supporting anonymous connections, will assign a username to the client.

Returns:

a reference to this builder.

setServiceName

public B setServiceName(java.lang.String serviceName)

Set the service name of this XMPP service (i.e., the XMPP domain).

Parameters:

serviceName - the service name

Returns:

a reference to this builder.

setResource

public B setResource(java.lang.String resource)

Set the resource to use.

If resource is null, then the server will automatically create a resource for the client. Default resource is "Smack".

Parameters:

resource - the resource to use.

Returns:

a reference to this builder.

setHost

public B setHost(java.lang.String host)

setPort

public B setPort(int port)

setCallbackHandler

public B setCallbackHandler(javax.security.auth.callback.CallbackHandler callbackHandler)

Sets a CallbackHandler to obtain information, such as the password or principal information during the SASL authentication. A CallbackHandler will be used ONLY if no password was specified during the login while using SASL authentication.

Parameters:

callbackHandler - to obtain information, such as the password or principal information during the SASL authentication.

Returns:

a reference to this builder.

setSecurityMode

public B setSecurityMode(ConnectionConfiguration.SecurityMode securityMode)

Sets the TLS security mode used when making the connection. By default, the mode is ConnectionConfiguration.SecurityMode.enabled.

Parameters:

securityMode - the security mode.

Returns:

a reference to this builder.

setKeystorePath

public B setKeystorePath(java.lang.String keystorePath)

Sets the path to the keystore file. The key store file contains the certificates that may be used to authenticate the client to the server, in the event the server requests or requires it.

Parameters:

keystorePath - the path to the keystore file.

Returns:

a reference to this builder.

setKeystoreType

public B setKeystoreType(java.lang.String keystoreType)

Sets the keystore type.

Parameters:

keystoreType - the keystore type.

Returns:

a reference to this builder.

setPKCS11Library

public B setPKCS11Library(java.lang.String pkcs11Library)

Sets the PKCS11 library file location, needed when the Keystore type is PKCS11

Parameters:

pkcs11Library - the path to the PKCS11 library file.

Returns:

a reference to this builder.

setCustomSSLContext

public B setCustomSSLContext(javax.net.ssl.SSLContext context)

Sets a custom SSLContext for creating SSL sockets.

For more information on how to create a SSLContext see Java Secure Socket Extension (JSEE) Reference Guide: Creating Your Own X509TrustManager

Parameters:

context - the custom SSLContext for new sockets.

Returns:

a reference to this builder.

setEnabledSSLProtocols

public B setEnabledSSLProtocols(java.lang.String[] enabledSSLProtocols)

Set the enabled SSL/TLS protocols.

Parameters:

enabledSSLProtocols -

Returns:

a reference to this builder.

setEnabledSSLCiphers

public B setEnabledSSLCiphers(java.lang.String[] enabledSSLCiphers)

Set the enabled SSL/TLS ciphers.

Parameters:

Returns:

a reference to this builder.

setHostnameVerifier

public B setHostnameVerifier(javax.net.ssl.HostnameVerifier verifier)

Set the HostnameVerifier used to verify the hostname of SSLSockets used by XMPP connections created with this ConnectionConfiguration.

Parameters:

verifier -

Returns:

a reference to this builder.

setLegacySessionDisabled

public B setLegacySessionDisabled(boolean legacySessionDisabled)

Sets if a Session will be requested on login if the server supports it. Although this was mandatory on RFC 3921, RFC 6120/6121 don't even mention this part of the protocol.

Parameters:

legacySessionDisabled - if a session has to be requested when logging in.

Returns:

a reference to this builder.

setRosterLoadedAtLogin

public B setRosterLoadedAtLogin(boolean rosterLoadedAtLogin)

Sets if the roster will be loaded from the server when logging in. This is the common behaviour for clients but sometimes clients may want to differ this or just never do it if not interested in rosters.

Parameters:

rosterLoadedAtLogin - if the roster will be loaded from the server when logging in.

Returns:

a reference to this builder.

setSendPresence

public B setSendPresence(boolean sendPresence)

Sets if an initial available presence will be sent to the server. By default an available presence will be sent to the server indicating that this presence is not online and available to receive messages. If you want to log in without being 'noticed' then pass a false value.

Parameters:

sendPresence - true if an initial available presence will be sent while logging in.

Returns:

a reference to this builder.

setRosterStore
