* Annotates the API with Spring's @NonNull and @Nullable annotations.
* Re-instates the hasValueConverter(:PersistentProperty) method.
* Removes explamation mark in Exception messages.
* Uses Java 17 language features to simplify code.
* Edits Javadoc.
Closes#2617.
Rename generics from C extends PersistentProperty to P extends PersistentProperty.
Refine conversion setup. Make PropertyValueConversions.getValueConverter(…) to return non-null. Return PropertyValueConversions from CustomConversions.
Resolves#2577Closes#2592
PropertyValueConverter read and write methods are never called with null values. Instead, PropertyValueConverter now defines readNull and writeNull to encapsulate null conversion. PropertyValueConversionService is a facade that encapsulates these details to simplify converter usage.
Resolves#2577Closes#2592
* Re-implement getNumberOfOccurrences(..) in terms of a Stream.
* Deprecate the mispelled getNumberOfOccurences(..) method and delegate to the new getNumberOfOccurrences(..) method.
* Edit Javadoc.
Closes#2600.
Looking up a PersistentEntity via ….getPersistentEntity(…) applies some massaging of the given type as it could be a proxy type created for a user type. That wrangling was not applied in ….hasPersistentEntity(…) which resulted in a call to that method with a proxy type yielding false although it shouldn't if we already have a PersistentEntity available for the corresponding user type.
We now explicitly lookup the entity by original type and, if it's not the user type itself, try to look up the entity for the latter.
Fixes#2589.
Avoid leaking internals from TypeInformation by exposing a ….toTypeDescriptor() method in TypeInformation directly. This causes the ResolvableType handling to become an implementation detail within ClassTypeInformation and avoid client code to manually deal with both ResolvableType and TypeDescriptor creation.
Changed MethodLookups back to use the resolved domain types as the advanced generics resolutions seems not to be needed here and we can avoid
Fixes#2518.
Remove Comparable requirement for general Range usage. Comparable is only required for the contains(…) check. Alternatively, accept a Comparator.
Closes#2571
We now consider IllegalArgumentException as marker for incompatible lambda payload that was introduced with Java 18's reflection rewrite that uses method handles internally.
Closes#2583
Replace outdated `null` acceptance for `Pageable` with `Pageable.unpaged()`
`QueryByExampleExecutor#findAll(Example<S> example, Pageable pageable)` should does not accept null values since there is `Pageable.unpaged()`. Furthermore, the same applies to `PagingAndSortingRepository#findAll(Pageable pageable)`.

Closes#2574
Increase visibility of converter builders.
Refine generics naming towards DV/SV instead of A/B to easier identify store-native values and domains-specific values in the API. Refactor PropertyValueConversions.hasValueConverter into a non-default method.
Tweak documentation.
See #1484
Original pull request: #2566.
Introduce a builder API to register PropertyValueConverters using simple (Bi)Functions. Additional methods on ValueConversionContext to enable advanced use cases in converter implementation. Tweak generics of VCC to be able to expose store-specific PersistentProperty implementations via the context.
See #1484
Original pull request: #2566.
We now accept Object-typed values to allow broader reuse of QuerydslPredicateBuilder. The conversion into the actual value considers the origin type and checks assignability before employing the ConversionService.
Closes#2573
Move simple Spring Converter implementation that allow to create DTOs from a source object previously copied amongst a variety of store modules.
Issue #2476.
Move to @PersistenceCreator as canonical annotation to explicitly express constructors and methods to be used to create domain object instances from persistence operations. Removed @FactoryMethod as it's not needed anymore. @PersistenceConstructor is now deprecated.
Renamed EntityCreatorMetadata(Support|Discoverer) to InstanceCreatorMetadata(Support|Discoverer) to avoid further manifestation of the notion of an entity in the metamodel as it's not used to only handle entities.
Issue #2476.
Moved Vavr collection converters into a type in the utility package. Register the converters via CustomConversions.registerConvertersIn(…) to make sure that all the Spring Data object mapping converters automatically benefit from a ConversionService that is capable of translating between Java-native collections and Vavr ones.
Issue #2511.
Let List… interface variants extend their base parent so that List-based variants participate in the type hierarchy.
See #2538
Original pull request: #2538.
This introduces the interfaces
* `ListCrudRepository`
* `ListQuerydslPredicateExecutor`
* `ListQueryByExampleExecutor`
They return `List` instead of `Iterable` when returning multiple entities.
They can be used in the same way the interfaces without the `List` prefix can be used.
Closes#2535.
Original pull request: #2538.
This way they can be combined with different variants of CrudRepositories.
This affects
`PagingAndSortingRepository`, `ReactiveSortingRepository`, `CoroutineSortingRepository`, and `RxJavaSortingRepository`.
Any repository implementing those interfaces now needs to also implement a suitable CRUD repository, or needs to manually add the methods from a CRUD repository as needed.
Closes#2537
Original pull request: #2540.
We now remove fully our own class-reading visitors as AnnotationMetadata exposes getDeclaredMethods.
MethodsMetadataReaderFactory and MethodsMetadataReader remain deprecated bridging return types to retain backward compatibility.
Closes#2520
Use var instead of explicit local types where applicable. Use pattern variable instead instanceof and cast. Prefer loops and nullable types over Stream and Optional. Convert classes to records where applicable.
See #2465
