Usage

From source file:org.hubiquitus.hapi.client.HClient.java

/**
 * The hAPI sends the hMessage to the hserver which transfer it to the specified actor.
 * The hserver will perform one of the following actions :
 *  (1). If the actor is a channel (ie : #channelName@domain) the hserver will perform a publish operation of the provided hMessage to the channel and send an hMessage with hResult payload containing the published message and cmd name set with hsend to acknowledge publishing only if a timeout value has been provided.
 *  (2). If the actor is either session and payload type is hCommand the server will handle it. In other cases, it will send an hMessage with a hResult error NOT_AUTHORIZED. Only if the timeout is provided.
 *  (3). If the actor is a jid, hserver will relay the message to the relevant actor.
 * @param message : The message to send. Mandatory.
 * @param messageDelegate : If provided, called by the hAPI when the first message refering to current message arrive . Not mandatory.
 *//*  w  w w.  j a v  a2  s  . co m*/
