Class LocalMUCUser

java.lang.Object
  org.jivesoftware.openfire.muc.spi.LocalMUCUser

All Implemented Interfaces:

ChannelHandler, MUCUser

public class LocalMUCUser
extends Object
implements MUCUser

Representation of users interacting with the chat service. A user may join serveral rooms hosted by the chat service. That means that we are going to have an instance of this class for the user and several MUCRoles for each joined room.

This room occupant is being hosted by this JVM. When the room occupant is hosted by another cluster node then an instance of RemoteMUCRole will be used instead.

Method Detail

isJoined

public boolean isJoined()

Returns true if the user is currently present in one or more rooms.

Returns:

true if the user is currently present in one or more rooms.

getRoles

public Collection<LocalMUCRole> getRoles()

Get all roles for this user.

Returns:

Iterator over all roles for this user

addRole

public void addRole(String roomName,
                    LocalMUCRole role)

Adds the role of the user in a particular room.

Parameters:

roomName - The name of the room.

role - The new role of the user.

removeRole

public void removeRole(String roomName)

Removes the role of the user in a particular room.

Note: PREREQUISITE: A lock on this object has already been obtained.

Parameters:

roomName - The name of the room we're being removed

getLastPacketTime

public long getLastPacketTime()

Get time (in milliseconds from System currentTimeMillis()) since last packet.

Returns:

The time when the last packet was sent from this user

getAddress

public JID getAddress()

Obtain the address of the user. The address is used by services like the core server packet router to determine if a packet should be sent to the handler. Handlers that are working on behalf of the server should use the generic server hostname address (e.g. server.com).

Specified by:

getAddress in interface MUCUser

Returns:

the address of the packet handler.

process

public void process(Packet packet)
             throws UnauthorizedException,
                    PacketException

Description copied from interface: ChannelHandler

Process an XMPP packet.

Specified by:

process in interface ChannelHandler

Parameters:

packet - a packet to process.

Throws:

UnauthorizedException - if not allowed to process the packet.

PacketException - thrown if the packet is malformed (results in the sender's session being shutdown).

process

public void process(Message packet)

This method does all packet routing in the chat server. Packet routing is actually very simple:

• Discover the room the user is talking to (server packets are dropped)
• If the room is not registered and this is a presence "available" packet, try to join the room
• If the room is registered, and presence "unavailable" leave the room
• Otherwise, rewrite the sender address and send to the room.

Parameters:

packet - The packet to route.

process

public void process(IQ packet)

process

public void process(Presence packet)
