类 AnnotationTypeMappings

java.lang.Object

cn.taketoday.core.annotation.AnnotationTypeMappings

所有已实现的接口:

Iterable<AnnotationTypeMapping>

final class AnnotationTypeMappings
extends Object
implements Iterable<AnnotationTypeMapping>

Provides AnnotationTypeMapping information for a single source annotation type. Performs a recursive breadth first crawl of all meta-annotations to ultimately provide a quick way to map the attributes of a root Annotation.

Supports convention based merging of meta-annotations as well as implicit and explicit @AliasFor aliases. Also provides information about mirrored attributes.

This class is designed to be cached so that meta-annotations only need to be searched once, regardless of how many times they are actually used.

从以下版本开始:

4.0

size

int size()

Get the total number of contained mappings.

返回:

the total number of mappings

get

AnnotationTypeMapping get(int index)

Get an individual mapping from this instance.

Index 0 will always return the root mapping; higher indexes will return meta-annotation mappings.

参数:

index - the index to return

返回:

the AnnotationTypeMapping

抛出:

IndexOutOfBoundsException - if the index is out of range (index < 0 || index >= size())

iterator

public Iterator<AnnotationTypeMapping> iterator()

指定者:

iterator 在接口中 Iterable<AnnotationTypeMapping>

forEach

public void forEach(Consumer<? super AnnotationTypeMapping> action)

指定者:

forEach 在接口中 Iterable<AnnotationTypeMapping>

spliterator

public Spliterator<AnnotationTypeMapping> spliterator()

指定者:

spliterator 在接口中 Iterable<AnnotationTypeMapping>

forAnnotationType

static AnnotationTypeMappings forAnnotationType(Class<? extends Annotation> annotationType)

Create AnnotationTypeMappings for the specified annotation type.

参数:

annotationType - the source annotation type

返回:

type mappings for the annotation type

forAnnotationType

static AnnotationTypeMappings forAnnotationType(Class<? extends Annotation> annotationType,
 Set<Class<? extends Annotation>> visitedAnnotationTypes)

Create AnnotationTypeMappings for the specified annotation type.

参数:

annotationType - the source annotation type

visitedAnnotationTypes - the set of annotations that we have already visited; used to avoid infinite recursion for recursive annotations which some JVM languages support (such as Kotlin)

返回:

type mappings for the annotation type

forAnnotationType

static AnnotationTypeMappings forAnnotationType(Class<? extends Annotation> annotationType,
 RepeatableContainers repeatableContainers,
 AnnotationFilter annotationFilter)

Create AnnotationTypeMappings for the specified annotation type.

参数:

annotationType - the source annotation type

repeatableContainers - the repeatable containers that may be used by the meta-annotations

annotationFilter - the annotation filter used to limit which annotations are considered

返回:

type mappings for the annotation type

forAnnotationType

private static AnnotationTypeMappings forAnnotationType(Class<? extends Annotation> annotationType,
 RepeatableContainers repeatableContainers,
 AnnotationFilter annotationFilter,
 Set<Class<? extends Annotation>> visitedAnnotationTypes)

Create AnnotationTypeMappings for the specified annotation type.

参数:

annotationType - the source annotation type

repeatableContainers - the repeatable containers that may be used by the meta-annotations

annotationFilter - the annotation filter used to limit which annotations are considered

visitedAnnotationTypes - the set of annotations that we have already visited; used to avoid infinite recursion for recursive annotations which some JVM languages support (such as Kotlin)
