AbstractMetaDataEvent (org.refcodes:refcodes-observer 1.10.3 API)

java.lang.Object
- org.refcodes.observer.AbstractEvent<SRC>
- - org.refcodes.observer.AbstractMetaDataEvent<EM,SRC>

Type Parameters:

EM - The type of the EventMetaData

SRC - The type of the source in question.

All Implemented Interfaces:

org.refcodes.mixin.MetaDataAccessor<EM>, org.refcodes.mixin.SourceAccessor<EM>, GenericEvent<EM>, GenericMetaDataEvent<EM,SRC>

Direct Known Subclasses:

AbstractPayloadMetaDataEvent, MetaDataEventImpl
```
public abstract class AbstractMetaDataEvent<EM extends EventMetaData,SRC>
extends AbstractEvent<SRC>
implements GenericMetaDataEvent<EM,SRC>
```
Ready to use GenericActionEvent storing a defined set of EventMetaData.
TIPP: In order to distinguish AbstractMetaDataEvent instances from each other, create an actions enumeration, enumerating the various event actions you support. Pass the actual action you intend to notify upon to the according constructor, as an Observer you may use the declarative method EventMatcherSugar.actionEqualWith(Object) to test whether your action was notified (or a simple switch case statement).
