AbstractMatcherFilter<E>
EvaluatorFilter<E>
The value of the `AbstractMatcherFilter.onMatch` and `AbstractMatcherFilter.onMismatch` attributes is set to `FilterReply.NEUTRAL`, so that a badly configured evaluator filter does not disturb the functioning of the filter chain.
Filter<E>
Users should extend this class to implement customized event filtering.
