EventTable, Iterable<EventBean>

public class PropertyIndexedEventTableCoerceAll
extends PropertyIndexedEventTableCoerceAdd

Index that organizes events by the event property values into hash buckets. Based on a HashMap with MultiKeyUntyped keys that store the property values.

Performs coercion of the index keys before storing the keys, and coercion of the lookup keys before lookup.

Takes a list of property names as parameter. Doesn't care which event type the events have as long as the properties exist. If the same event is added twice, the class throws an exception on add.
