EventPropertyGetterUseful for dynamic properties of the syntax "property?" and the dynamic nested/indexed/mapped versions. Dynamic nested properties follow the syntax "property?.nested" which is equivalent to "property?.nested?". If any of the properties in the path of a dynamic nested property return null, the dynamic nested property does not exists and the method returns false.
For non-dynamic properties, this method always returns true since a getter would not be available unless

EventPropertyGetterEventBean 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.
