We now provide an abstraction to describe a collection of entity types that can be provided to the mapping context as improvement over `Set<Class>` for easier context setup.

Slight refinements in TypeDiscoverer.equals(…) / hashCode() that are still not completely valid, are different enough to work for differentiating use cases but not 100% efficient for cache cases. Captured outstanding work in spring-projects/spring-data-commons#2643.
Reimplemented ….repository.query.Parameter.isDynamicProjectParameter(…) to bild on TypeInformation completely and properly unwrapp *all* wrapper types for type comparison.
Related ticket #2312.
Reworked the implementation of the TypeInformation type hierarchy to be based on Spring's ResolvableType for most of the heavy-lifting.

Spring Data Commons has a hard-coded list of special types than can be included in query methods including Pageable and Sort.
A custom finder with PageRequest, even though it extends Pageable, will fail when it would work fine with a narrowed input. This extends the list using an assignability check.

We now return a default value for invocations of methods returning a primitive value to pass the AOP infrastructure's check for compatible values. Before, that barked at the null value returned for the invocation.
Fixes#2612.
Removed the removal of the general collection-to-object converter as apparently some downstream Spring Data modules rely on it. This theoretically allows conversions of collections into maps but we now simply don't assume that not to work anymore.
Issue #2619.
Custom collection support is now centralized in ….util.CustomCollections. It exposes API to detect whether a type is a map or collection, identifies the map base type etc.
Support for different collection implementations is externalized via the CustomCollectionRegistrar SPI that allows to define implementations via spring.factories. The current support for Vavr collections has been moved into an implementation of that, VavrCollections.
Unit tests for custom collection handling and conversion previously living in QueryExecutionConverterUnitTests have been moved into CustomCollectionsUnitTests.
Fixes#2619.
* 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
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.
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.
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.
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
