public interface EventCollection
extends Iterable<EventBean>

Interface that marks an event collection. Every event in the event collection must be of the same event type, as defined by the getEventType() call.

Method Summary

Modifier and Type	Method and Description
EventType	getEventType() Provides metadata information about the type of object the event collection contains.
Iterator<EventBean>	iterator() Allows iteration through all elements in this event collection.

Methods inherited from interface java.lang.Iterable

forEach, spliterator

Method Detail

getEventType

EventType getEventType()

Provides metadata information about the type of object the event collection contains.

Returns:

metadata for the objects in the collection

iterator

Iterator<EventBean> iterator()

Allows iteration through all elements in this event collection. The iterator will return the elements in the collection in their natural order, or, if there is no natural ordering, in some unpredictable order.

Specified by:

iterator in interface Iterable<EventBean>

Returns:

an iterator which will go through all current elements in the collection.
