streams.esper

Class EsperData

java.lang.Object

streams.esper.EsperData

All Implemented Interfaces:

Serializable, Map<String,Serializable>, stream.Data

public class EsperData
extends Object
implements stream.Data

An Esper data item extends the Data by a setter method for the map properties. This allows to re-user Esper types and we hence have to define no further types.
