Examples of com.espertech.esper.filter.FilterService

com.espertech.esper.filter.FilterService
Interface for filtering events by event type and event property values. Allows adding and removing filters.
Filters are defined by a {@link FilterSpecCompiled} and are associated with a {@link FilterHandle}callback. Implementations may decide if the same filter callback can be registered twice for different or some filter specifications.
The performance of an implementation of this service is crucial in achieving a high overall event throughput.

        FilterValueSet filterValues = evalFilterNode.getFactoryNode().getFilterSpec().getValueSet(beginState, evalFilterNode.getContext().getAgentInstanceContext(), evalFilterNode.getAddendumFilters());
        filterService.add(filterValues, handle);
