Class ServiceBasedValueObjectConverter<O extends Identifiable, VO extends IdentifiableValueObject<O>>

java.lang.Object

ubic.gemma.persistence.util.ServiceBasedEntityConverter<O>

ubic.gemma.persistence.util.ServiceBasedValueObjectConverter<O,VO>

Type Parameters:

O - the type of value object this converter consumes and also produces (as inherited from ServiceBasedEntityConverter

VO - the type of value object this converter produces

All Implemented Interfaces:

org.springframework.core.convert.converter.ConditionalConverter, org.springframework.core.convert.converter.ConditionalGenericConverter, org.springframework.core.convert.converter.GenericConverter

public class ServiceBasedValueObjectConverter<O extends Identifiable, VO extends IdentifiableValueObject<O>>
extends ServiceBasedEntityConverter<O>
implements org.springframework.core.convert.converter.ConditionalGenericConverter

Perform conversion to value object by entity, ID and collections of entities and IDs and also to entity by ID and collection of IDs.

The converter recognize two cases: converting O → VO and converting Collection of O to List of VO by calling respectively BaseVoEnabledService.loadValueObject(Identifiable) and BaseVoEnabledService.loadValueObjects(Collection).

This implementation also work with supertypes of the designated VO and subtypes of the O. For example, you can perform generic conversion to IdentifiableValueObject without having to mention the specific type of value object you ultimately want.
