PRESERVING EVENT DATA FOR LAZILY-LOADED MACRO COMPONENTS IN A PUBLISH/SUBSCRIBE SYSTEM

摘要

A method, system and computer program product for preserving event data for lazily-loaded macro components. Upon detecting an event published by a publisher, the logical channel of the detected event is identified. If one of the macro components to be lazily-loaded is a primary receiver for that logical channel (determined by performing a table-lookup of a data structure containing a listing of macro components and their associated logical channels for which they are to be the primary receivers), then the indication of the logical channel of the detected event along with the data of the published event are stored as a key/value pair in a data structure. Upon the macro component to be lazily-loaded having been loaded, the data of the published event associated with the logical channel for which the loaded macro component is a primary receiver is retrieved and transmitted to that logical channel.
