public class UniversalFilter extends Object implements EventFilter
Filter
implementation, which can be parametrised by
a UniversalFilter.Selector
and a Predicate
. The selector maps a call back
on this filter to a NodeState
. That node state is in turn passed
to the predicate for determining whether to include or to exclude the
respective event.Modifier and Type | Class and Description |

UniversalFilter.Selector
A selector instance maps call backs on
Filters to NodeState instances,
which should be used for determining inclusion or exclusion of the associated event. |

UniversalFilter(NodeState before,
NodeState after,
