    摘要: A situation object instantiator (SOI) receives a request from a client including a typekey. Available situations are retrieved. For a retrieved situation, a call to an evaluator is made. If the situation is active a check is made to see if an instantiator exists for the typekey and situation. If so, the object instantiator is called, it returns an instance to the SOI, and the SOI returns the instance to the client. If not, more situations are retrieved until the situations are exhausted, and such is communicated to the client.

    摘要: A multicast host for communicating information published about any one of a set of topics to one or more authorised subscribers to those topics, the set of topics being partitioned into one or more partition elements, each partition element having a partition element encryption key associated therewith, wherein each of the one or more partition elements is a disjoint proper subset of the set of topics, the host comprising: means for receiving information relating to a topic; means for determining a partition element for the topic; means for retrieving a partition element encryption key associated with the partition element; means for encrypting the information with the retrieved partition element encryption key; and means for communicating the information to the one or more authorised subscribers.
