When an application publishes a message to a topic within that topic space , the message flows to every publication point for that topic space , as shown in figure 5
当应用程序将消息发布到主题空间中的主题上时，消息将通过该主题空间的所有发布点，如图5所示。
After the first subscriber subscribes , when messages are published to the topic , the publication point adds the messages to the topic space until the last subscriber unsubscribes
第一个订户订阅后，发布点会在消息发布到主题时将其添加到主题空间，直到最后一个订户取消订阅为止。
Publication points are used not only for applications to add and remove messages on topics , but also to propagate messages from one messaging engine to the others in the bus
发布点不仅供应用程序用于添加和删除与主题有关的消息，还可用于将来自一个消息传递引擎的消息传播到总线中的其他消息传递引擎上。
However , as described earlier , one does not have to specify which bus member will host the destination ; every messaging engine in the bus automatically has a publication point representing that topic space
不过，如前面所述，并不指定哪个总线成员将承载目的地；总线中的每个消息引擎将自动用发布点表示主题空间。
