Interface ManyReferenceMergedAs<M>

Type Parameters:

M - the type of the multi-valued reference after mapping

All Superinterfaces:

ManyReferenceMapper, ReferenceMapper, ValueMapper

@ParametersAreNonnullByDefault
public interface ManyReferenceMergedAs<M>
extends ValueMapper, ManyReferenceMapper

A ManyReferenceMapper that provides a default behavior to use M instead of a set of Id for multi-valued references.

This mapper merges the multi-valued references into a single value.

Method Summary

Modifier and Type	Method and Description
default void	addAllReferences(ManyFeatureBean feature, List<Id> collection) Adds all the collection to the specified feature from the position of the feature.
default void	addReference(ManyFeatureBean feature, Id reference) Adds the reference to the specified feature at a defined position.
default Stream<Id>	allReferencesOf(SingleFeatureBean feature) Retrieves all references of the specified feature.
Converter<List<Id>,M>	manyReferenceMerger() Returns the converter used to transform a ordered list of references to the desired type.
default Optional<Id>	referenceFor(ManyFeatureBean feature, Id reference) Defines the reference of the specified feature at a defined position.
default Optional<Id>	referenceOf(ManyFeatureBean feature) Retrieves the reference of the specified feature at a defined position.
default void	removeAllReferences(SingleFeatureBean feature) Removes all references of the specified feature.
default Optional<Id>	removeReference(ManyFeatureBean feature) Removes the reference of the specified feature at a defined position.
default Optional<Integer>	sizeOfReference(SingleFeatureBean feature) Returns the number of reference of the specified feature.

Method Detail

referenceOf

@Nonnull
default Optional<Id> referenceOf(ManyFeatureBean feature)

Description copied from interface: ManyReferenceMapper

Retrieves the reference of the specified feature at a defined position.

Specified by:

referenceOf in interface ManyReferenceMapper

Parameters:

feature - the bean identifying the multi-valued reference

Returns:

an Optional containing the reference, or Optional.empty() if the feature hasn't any reference or doesn't exist

allReferencesOf

@Nonnull
default Stream<Id> allReferencesOf(SingleFeatureBean feature)

Description copied from interface: ManyReferenceMapper

Retrieves all references of the specified feature.

Specified by:

allReferencesOf in interface ManyReferenceMapper

Parameters:

feature - the bean identifying the multi-valued reference

Returns:

an immutable ordered Stream over all references

referenceFor

@Nonnull
default Optional<Id> referenceFor(ManyFeatureBean feature,
                                            Id reference)

Description copied from interface: ManyReferenceMapper

Defines the reference of the specified feature at a defined position.

Specified by:

referenceFor in interface ManyReferenceMapper

Parameters:

feature - the bean identifying the multi-valued reference

reference - the reference to set

Returns:

an Optional containing the previous reference of the feature, or Optional.empty() if the feature has no reference before
