Interface AggregateIdentifierProcessor

All Superinterfaces:
org.springframework.plugin.core.Plugin<Class<?>>
All Known Implementing Classes:
UriTemplateIdentifierProcessor
public interface AggregateIdentifierProcessor extends org.springframework.plugin.core.Plugin<Class<?>>
SPI interface to customize identifier to aggregate mapping in RepositoryMappingModule. AggregareIdentifierProcessor implementations can be registered with it to pre- and post process the source and target identifier values obtained from source and target objects.

    postProcessIdentifier(Object identifier, Class<?> sourceType, Class<?> targetType)
    Post process the identifier obtained from the aggregate to finally constitute the value to be set on the target object.
    default Object
    preProcessIdentifier(Object identifier, Class<?> targetType)
    Pre-process the identifier obtained from the source object to finally resolve an aggregate from the returned value.

  • Method Details

    • preProcessIdentifier

      default Object preProcessIdentifier(Object identifier, Class<?> targetType)
      Pre-process the identifier obtained from the source object to finally resolve an aggregate from the returned value.
      Parameters:
      identifier - the original identifier obtained from the source object. Must not be null.
      targetType - the target aggregate type the given identifier is supposed to eventually identify. Must not be null.
      Returns:
      will never be null.

    • postProcessIdentifier

      default Object postProcessIdentifier(Object identifier, Class<?> sourceType, Class<?> targetType)
      Post process the identifier obtained from the aggregate to finally constitute the value to be set on the target object.
      Parameters:
      identifier - the original identifier of the aggregate to be transformed into the target object's property value. Must not be null.
      sourceType - the source aggregate type. Must not be null.
      targetType - the target type to create for this aggregate. Can be used to decide whether to actually apply post-processing.
      Returns:
      will never be null.

    • getAdditionalIdentifierTypes

      default Collection<Class<?>> getAdditionalIdentifierTypes()
      Returns additional identifier types that the processor will be able to handle.
      Returns:
      will never be null.
