getFragment

public Object getFragment(EventBean eventBean)

Description copied from interface: EventPropertyGetter

Returns EventBean or array of EventBean for a property name or property expression.

For use with properties whose value is itself an event or whose value can be represented as an event by the underlying event representation.

The EventType of the EventBean instance(s) returned by this method can be determined by EventType.getFragmentType(String). Use EventPropertyDescriptor to obtain a list of properties that return fragments from an event type.

Returns null if the property value is null or the property value cannot be represented as a fragment by the underlying representation.

Specified by:

getFragment in interface EventPropertyGetter

Parameters:

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

Returns:

the value of a property as an EventBean or array of EventBean
