Interface EventMatcher<E extends Event<?>>

Type Parameters:
E - The matchee type.
All Superinterfaces:
org.refcodes.mixin.AliasAccessor, org.refcodes.matcher.Matchable<E>, org.refcodes.matcher.Matcher<E>, org.refcodes.mixin.Schemable
All Known Subinterfaces:
MetaDataEventMatcher<E>
All Known Implementing Classes:
AbstractEventMatcher, ActionEqualWithEventMatcher, AliasEqualWithEventMatcher, CatchAllEventMatcher, CatchNoneEventMatcher, ChannelEqualWithEventMatcher, GroupEqualWithEventMatcher, PublisherTypeOfEventMatcher, UniversalIdEqualWithEventMatcher
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface EventMatcher<E extends Event<?>> extends org.refcodes.matcher.Matcher<E>
This interface typifies the Matcher interface for the usage with ActionEvent instances. An EventMatcher most commonly uses the EventMetaData (as defined with the MetaDataEvent) in order to determine whether an ActionEvent matches EventMetaData properties or not.
