setNodeInformationProvider

public void setNodeInformationProvider(String node,
                                       NodeInformationProvider listener)

Sets the NodeInformationProvider responsible for providing information (ie items) related to a given node. Every time this client receives a disco request regarding the items of a given node, the provider associated to that node will be the responsible for providing the requested information.

In MUC, a node could be 'http://jabber.org/protocol/muc#rooms' which means that the NodeInformationProvider will provide information about the rooms where the user has joined.

Parameters:

node - the node whose items will be provided by the NodeInformationProvider.

listener - the NodeInformationProvider responsible for providing items related to the node.

removeNodeInformationProvider

public void removeNodeInformationProvider(String node)

Removes the NodeInformationProvider responsible for providing information (ie items) related to a given node. This means that no more information will be available for the specified node. In MUC, a node could be 'http://jabber.org/protocol/muc#rooms' which means that the NodeInformationProvider will provide information about the rooms where the user has joined.

Parameters:

node - the node to remove the associated NodeInformationProvider.

getFeatures

public List<String> getFeatures()

Returns the supported features by this XMPP entity.

The result is a copied modifiable list of the original features.

Returns:

a List of the supported features by this XMPP entity.

addFeature

public void addFeature(String feature)

Registers that a new feature is supported by this XMPP entity. When this client is queried for its information the registered features will be answered.

Since no stanza is actually sent to the server it is safe to perform this operation before logging to the server. In fact, you may want to configure the supported features before logging to the server so that the information is already available if it is required upon login.

Parameters:

feature - the feature to register as supported.

removeFeature

public void removeFeature(String feature)

Removes the specified feature from the supported features by this XMPP entity.

Since no stanza is actually sent to the server it is safe to perform this operation before logging to the server.

Parameters:

feature - the feature to remove from the supported features.

includesFeature

public boolean includesFeature(String feature)

Returns true if the specified feature is registered in the ServiceDiscoveryManager.

Parameters:

feature - the feature to look for.

Returns:

a boolean indicating if the specified featured is registered or not.

setExtendedInfo

public void setExtendedInfo(DataForm info)

Registers extended discovery information of this XMPP entity. When this client is queried for its information this data form will be returned as specified by XEP-0128.

Since no stanza is actually sent to the server it is safe to perform this operation before logging to the server. In fact, you may want to configure the extended info before logging to the server so that the information is already available if it is required upon login.

Parameters:

info - the data form that contains the extend service discovery information.

getExtendedInfo

public DataForm getExtendedInfo()

Returns the data form that is set as extended information for this Service Discovery instance (XEP-0128).

Returns:

the data form

See Also:

Returns:

the data form as List of PacketExtensions

removeExtendedInfo

public void removeExtendedInfo()

Removes the data form containing extended service discovery information from the information returned by this XMPP entity.

Since no stanza is actually sent to the server it is safe to perform this operation before logging to the server.
