Class MetaDataEventImpl<SRC>

java.lang.Object

org.refcodes.observer.impls.AbstractEvent<SRC>

org.refcodes.observer.impls.MetaDataEventImpl<SRC>

Type Parameters:

SRC - The type of the source in question.

All Implemented Interfaces:

MetaDataAccessor<EventMetaData>, SourceAccessor<SRC>, Event<SRC>, MetaDataEvent<SRC>

public class MetaDataEventImpl<SRC>
extends AbstractEvent<SRC>
implements MetaDataEvent<SRC>

Ready to use ActionEvent storing a defined set of EventMetaData.

TIPP: In order to distinguish MetaDataEventImpl 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 EventMatcherByDeclaration.actionEqualWith(Object) to test whether your action was notified (or a simple switch case statement).

Constructor Detail

MetaDataEventImpl

public MetaDataEventImpl(EventMetaData aEventMetaData,
                         SRC aSource)

Constructs an event with the given meta Data.

Parameters:

aEventMetaData - The meta data to by supplied by the event.

aSource - The source from which this event originated.

MetaDataEventImpl

public MetaDataEventImpl(String channel,
                         SRC aSource)

Constructs an event with the given meta Data.

Parameters:

channel - The value for ChannelAccessor.getChannel() attribute.

aSource - The source from which this event originated.

MetaDataEventImpl

public MetaDataEventImpl(SRC aSource)

Constructs an event with the given meta Data.

Type Parameters:

A - The type of the action stored in the event. CAUTION: The drawback of not using generic generic type declaration on a class level is no granted type safety, the advantage is the ease of use: Sub-classes can be used out of the box.

Parameters:

aEventMetaData - The meta data to by supplied by the event.

aAction - The action which the ActionEvent represents.

aSource - The source from which this event originated.
