All Implemented Interfaces:

AttributeConverter

public class ORedMultiValuePropertyFlattener
extends MultiValuePropertyFlattener

A flattening converter that performs flattening by performing a logical OR operation on the target attribute values. This can be set on a collection of enum properties where the enum's ordinals form a binary sequence. The ORing is done by converting the symbolic names to the corresponding ordinal values and performing the OR against all attribute values. Note that in from connector direction the order of values output by un-flattening may not coincide to the order in which they were sent as the flattening itself is lossy.
