Examples of EventPropertyRendererContext

com.espertech.esper.client.util.EventPropertyRendererContext
Context for use with the {@link EventPropertyRenderer} interface for use with the JSON or XML event renderes to handle custom event property rendering.
Do not retain a handle to the renderer context as this object changes for each event property.
