Enum Class MergedAnnotations.SearchStrategy

java.lang.Object

java.lang.Enum<MergedAnnotations.SearchStrategy>

cn.taketoday.core.annotation.MergedAnnotations.SearchStrategy

所有已实现的接口:

Serializable, Comparable<MergedAnnotations.SearchStrategy>, Constable

封闭接口:

MergedAnnotations

public static enum MergedAnnotations.SearchStrategy
extends Enum<MergedAnnotations.SearchStrategy>

Search strategies supported by MergedAnnotations.search(SearchStrategy) as well as MergedAnnotations.from(AnnotatedElement, SearchStrategy) and variants of that method.

Each strategy creates a different set of aggregates that will be combined to create the final MergedAnnotations.

枚举常量详细资料

DIRECT

public static final MergedAnnotations.SearchStrategy DIRECT

Find only directly declared annotations, without considering @Inherited annotations and without searching superclasses or implemented interfaces.

INHERITED_ANNOTATIONS

public static final MergedAnnotations.SearchStrategy INHERITED_ANNOTATIONS

Find all directly declared annotations as well as any @Inherited superclass annotations.

This strategy is only really useful when used with Class types since the @Inherited annotation is ignored for all other annotated elements.

This strategy does not search implemented interfaces.

SUPERCLASS

public static final MergedAnnotations.SearchStrategy SUPERCLASS

Find all directly declared and superclass annotations.

This strategy is similar to INHERITED_ANNOTATIONS except the annotations do not need to be meta-annotated with @Inherited.

This strategy does not search implemented interfaces.

TYPE_HIERARCHY

public static final MergedAnnotations.SearchStrategy TYPE_HIERARCHY

Perform a full search of the entire type hierarchy, including superclasses and implemented interfaces.

When combined with MergedAnnotations.Search.withEnclosingClasses(Predicate), enclosing classes will also be recursively searched if the supplied Predicate evaluates to true.

Superclass and enclosing class annotations do not need to be meta-annotated with @Inherited.

方法详细资料

values

public static MergedAnnotations.SearchStrategy[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

返回:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static MergedAnnotations.SearchStrategy valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - 如果参数为空值
