public interface EventPropertyValueGetter

Get property values from an event instance for a given event property. Instances that implement this interface are usually bound to a particular EventType and cannot be used to access EventBean instances of a different type.

Method Summary

Object	get(EventBean eventBean) Return the value for the property in the event object specified when the instance was obtained.

Method Detail

get

Object get(EventBean eventBean)
    throws PropertyAccessException

Return the value for the property in the event object specified when the instance was obtained. Useful for fast access to event properties. Throws a PropertyAccessException if the getter instance doesn't match the EventType it was obtained from, and to indicate other property access problems.

Parameters:

eventBean - is the event to get the value of a property from

Returns:

value of property in event

Throws:

PropertyAccessException - to indicate that property access failed
