Service on top of the filter service for reuseing filter callbacks and their associated EventStream instances. Same filter specifications (equal) do not need to be added to the filter service twice and the EventStream instance that is the stream of events for that filter can be reused.

The following tables list the members exposed by the StreamReuseService type.

Public Methods

  NameDescription
CreateStream
Create or reuse existing EventStream instance representing that event filter. When called for some filters, should return same stream.
