Class ReflectionUtils.TypeMetadata

java.lang.Object

io.fluxzero.common.reflection.ReflectionUtils.TypeMetadata

Enclosing class:

ReflectionUtils

public static final class ReflectionUtils.TypeMetadata
extends Object

Lazily computed reflection metadata for a single Java type.

This is the central cache for type-level reflection in Fluxzero. It keeps the structural model of a type together in one place: methods, fields, property descriptors, type annotations, annotated members, cached property-path accessors, and compiled MemberInvoker instances.

annotatedExecutables

public List<Executable> annotatedExecutables(Class<? extends Annotation> annotation)

Returns annotated methods, including inherited methods, followed by annotated constructors declared by this type.

annotatedPropertyInvoker

public Optional<MemberInvoker> annotatedPropertyInvoker(Class<? extends Annotation> annotation)

getter

public Function<Object,Object> getter(String propertyPath)

setter

public BiConsumer<Object,Object> setter(String propertyPath)

propertyPath

public ReflectionUtils.TypeMetadata.PropertyPathMetadata propertyPath(String propertyPath)

invoker

public MemberInvoker invoker(Member member,
 boolean forceAccess)

specializedMetadata

public <M> M specializedMetadata(Class<M> metadataType,
 Function<Class<?>, ? extends M> factory)

Returns type-specific structural metadata owned by this central type cache.

SDK features can use this extension point for immutable metadata that is derived only from type(). Runtime or instance state must not be captured by the factory or the returned value.

Type Parameters:

M - metadata type

Parameters:

metadataType - unique metadata kind and expected result type

factory - computes the metadata from this Java type on first access

Returns:

the cached metadata instance

public <A extends Annotation> Optional<A> methodAnnotation(Executable executable,
 Class<? extends Annotation> annotation)

methodAnnotations

public <A extends Annotation> List<A> methodAnnotations(Executable executable,
