Enum Class MergedAnnotations.SearchStrategy

java.lang.Object

java.lang.Enum<MergedAnnotations.SearchStrategy>

org.springframework.core.annotation.MergedAnnotations.SearchStrategy

All Implemented Interfaces:

Serializable, Comparable<MergedAnnotations.SearchStrategy>, Constable

Enclosing interface:

MergedAnnotations

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

Search strategies supported by MergedAnnotations.from(AnnotatedElement, SearchStrategy).

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

Enum Constant Summary

Enum Constants

Enum Constant	Description
DIRECT	Find only directly declared annotations, without considering @Inherited annotations and without searching superclasses or implemented interfaces.
INHERITED_ANNOTATIONS	Find all directly declared annotations as well as any @Inherited superclass annotations.
SUPERCLASS	Find all directly declared and superclass annotations.
TYPE_HIERARCHY	Perform a full search of the entire type hierarchy, including superclasses and implemented interfaces.
TYPE_HIERARCHY_AND_ENCLOSING_CLASSES	Perform a full search of the entire type hierarchy on the source and any enclosing classes.

Method Summary

Modifier and Type	Method	Description
static MergedAnnotations.SearchStrategy	valueOf(String name)	Returns the enum constant of this class with the specified name.
static MergedAnnotations.SearchStrategy[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

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

TYPE_HIERARCHY_AND_ENCLOSING_CLASSES

public static final MergedAnnotations.SearchStrategy TYPE_HIERARCHY_AND_ENCLOSING_CLASSES

Perform a full search of the entire type hierarchy on the source and any enclosing classes. This strategy is similar to TYPE_HIERARCHY except that enclosing classes are also searched. Superclass annotations do not need to be meta-annotated with @Inherited. When searching a Method source, this strategy is identical to TYPE_HIERARCHY.

Method Details

values

public static MergedAnnotations.SearchStrategy[] values()

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

Returns:

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.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

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

NullPointerException - if the argument is null
