Package org.springframework.data.util

@NullMarked package org.springframework.data.util

Core utility APIs such as a type information framework to resolve generic types.

Class	Description
AnnotatedTypeScanner	Scanner to find types with annotations on the classpath.
AnnotationDetectionFieldCallback	A ReflectionUtils.FieldCallback that will inspect each field for a given annotation.
AnnotationDetectionMethodCallback<A extends Annotation>	ReflectionUtils.MethodCallback to find annotations of a given type.
BeanLookup	Simple helper to allow lenient lookup of beans of a given type from a ListableBeanFactory.
ClassUtils	Utility class to work with classes.
CloseableIterator<T>	A CloseableIterator serves as a bridging data structure for the underlying data store specific results that can be wrapped in a Java 8 java.util.stream.Stream.
DirectFieldAccessFallbackBeanWrapper	Custom extension of BeanWrapperImpl that falls back to direct field access in case the object or type being wrapped does not use accessor methods.
KotlinBeanInfoFactory	BeanInfoFactory specific to Kotlin types using Kotlin reflection to determine bean properties.
KotlinReflectionUtils	Reflection utility methods specific to Kotlin reflection.
Lazy<T>	Simple value type to delay the creation of an object using a Supplier returning the produced object for subsequent lookups.
Lock	Lock provides more extensive locking operations than can be obtained using synchronized methods and Lock.
Lock.AcquiredLock	An acquired lock can be used with try-with-resources for easier releasing.
MethodInvocationRecorder	API to record method invocations via method references on a proxy.
MethodInvocationRecorder.PropertyNameDetectionStrategy
MethodInvocationRecorder.Recorded<T>
MethodInvocationRecorder.Recorded.ToCollectionConverter<T,S>
MethodInvocationRecorder.Recorded.ToMapConverter<T,S>
NullableUtils	Deprecated. since 4.0 in favor of Nullness fully using JSpecify annotations instead of Spring Framework's own @Nullable and @NonNullApi annotations.
NullnessMethodInvocationValidator	Interceptor enforcing required return value and method parameter constraints declared on repository query methods.
Optionals	Utility methods to work with Optionals.
Pair<S,T>	A tuple of things.
ParameterTypes	Deprecated, for removal: This API element is subject to removal in a future version. since 4.0, this class is not intended for public use and will be removed in future versions.
ParsingUtils	Utility methods for String parsing.
Predicates	Utility methods to work with Predicates.
ProxyUtils	Proxy type detection utilities, extensible via ProxyUtils.ProxyDetector registered via Spring factories.
ProxyUtils.ProxyDetector	SPI to extend Spring's default proxy detection capabilities.
QTypeContributor
ReadWriteLock	A ReadWriteLock maintains a pair of associated locks, one for read-only operations and one for writing.
ReflectionUtils	Spring Data specific reflection utility methods and classes.
ReflectionUtils.AnnotationFieldFilter	A ReflectionUtils.FieldFilter for a given annotation.
ReflectionUtils.DescribedFieldFilter	A ReflectionUtils.FieldFilter that has a description.
Streamable<T>	Simple interface to ease streamability of Iterables.
StreamUtils	Spring Data specific Java Stream utility methods and classes.
TypeCollector	Collector to inspect domain types and discover the type graph that is relevant for Spring Data operations.
TypeCollector.ReachableTypes	Container for reachable types starting from a set of root types.
TypeCollector.TypeCollectorFilters	Strategy interface providing predicates to filter types, fields, and methods from being introspected and contributed to AOT processing.
TypeContributor
TypeScanner	A scanner that searches the classpath for matching types within given target packages.
TypeUtils
TypeUtils.TypeOps
TypeUtils.TypeOps.PackageFilter
Version	Value object to represent a Version consisting of major, minor and bugfix part.
