A list of filters. Reverse Polish Notation (RPN) is being used here to provide the most flexibility in defining more complex filters in the future. Each filter is represented by a list of entries. Each entry is a single RPN token. To create an entry, create the list of tokens as follows: More than one token can be contained in a single message. All fields of a single token must be in the same message. The lightStreamBrFilterStatus object of all intermediate tokens must contain the value 'intermediateToken'. The lightStreamBrFilterStatus object of the last token must contain the value 'complete'. When the last token is created with a status of 'complete' the status field of every prior token associated with that filter is set to 'complete'. When the filter is set to 'complete', it is available for use in a lightStreamBridgeFilterParameterEntry. The filter is not actually used until its ID is placed in a lightStreamBridgeFilterParameterEntry and the associated parameters are defined. A filter may be used more than once in the lightStreamBridgeFilterParameterTable. The agent does not permit the user to 'delete' the filter entry until it is removed from the lightStreamBridgeFilterParameterTable. When a filter is placed into or removed from the lightStreamBridgeFilterParameterTable, its new state becomes active immediately. The agent provides timeout service for partially constructed filters. If a manager doesn't complete a filter definition within the timeout period (currently 3 minutes), the agent removes all tokens associated with that filter.
