the class MultiUserChatManager method updateMultiUserChatService.

 *
 * Properties are tied to the ID, which will not change.

 * @param subdomain New subdomain to assign to the service.
 * @param description New description to assign to the service.

Example 2 with ServiceAddedEvent

use of org.jivesoftware.openfire.muc.cluster.ServiceAddedEvent in project Openfire by igniterealtime.

the class MultiUserChatManager method registerMultiUserChatService.

/**
 * Registers a new MultiUserChatService implementation to the manager.
 *
 * This is typically used if you have a custom MUC implementation that you want to register with the manager. In
 * other words, it may not be database stored and may follow special rules, implementing MultiUserChatService.
 * It is also used internally to register services from the database.
 *
 * Triggers the service to start up.
 *
 * This method has a boolean parameter that controls whether a 'new service added' event is to be sent to all other
 * cluster nodes. This generally is desirable when a new service is being created. A reason to _not_ send such an
 * event is when this method is being invoked as a result of receiving/processing such an event that was received
 * from another cluster node, or when initializing this instance from database content (which will occur on all
 * cluster nodes).
 *
 * @param service The MultiUserChatService to be registered.
 * @param allNodes true if a 'service added' event needs to be sent to other cluster nodes.
 * @see #createMultiUserChatService(String, String, boolean)
