类 RepeatableContainers

java.lang.Object

cn.taketoday.core.annotation.RepeatableContainers

直接已知子类:

RepeatableContainers.ExplicitRepeatableContainer, RepeatableContainers.StandardRepeatableContainers

public class RepeatableContainers
extends Object

Strategy used to determine annotations that act as containers for other annotations. The standard() method provides a default strategy that respects Java's @Repeatable support and should be suitable for most situations.

The valueOf(java.lang.Class<? extends java.lang.annotation.Annotation>, java.lang.Class<? extends java.lang.annotation.Annotation>) method can be used to register relationships for annotations that do not wish to use @Repeatable.

To completely disable repeatable support use none().

and

public RepeatableContainers and(Class<? extends Annotation> container,
 Class<? extends Annotation> repeatable)

Add an additional explicit relationship between a container and repeatable annotation.

WARNING: the arguments supplied to this method are in the reverse order of those supplied to valueOf(Class, Class)

参数:

container - the container annotation type

repeatable - the repeatable annotation type

返回:

a new RepeatableContainers instance

findRepeatedAnnotations

@Nullable
Annotation[] findRepeatedAnnotations(Annotation annotation)

equals

public boolean equals(@Nullable
 Object other)

覆盖:

equals 在类中 Object

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Object

none

public static RepeatableContainers none()

Create a RepeatableContainers instance that does not expand any repeatable annotations.

返回:

a RepeatableContainers instance

standard

public static RepeatableContainers standard()

Create a RepeatableContainers instance that searches using Java's @Repeatable annotation.

返回:

a RepeatableContainers instance

valueOf

public static RepeatableContainers valueOf(Class<? extends Annotation> repeatable,
 @Nullable
 Class<? extends Annotation> container)

Create a RepeatableContainers instance that uses predefined repeatable and container types.

参数:

repeatable - the contained repeatable annotation type

container - the container annotation type or null. If specified, this annotation must declare a value attribute returning an array of repeatable annotations. If not specified, the container will be deduced by inspecting the @Repeatable annotation on repeatable.

返回:

a RepeatableContainers instance

抛出:

IllegalArgumentException - if the supplied container type is null and the annotation type is not a repeatable annotation

AnnotationConfigurationException - if the supplied container type is not a properly configured container for a repeatable annotation

invokeAnnotationMethod

private static Object invokeAnnotationMethod(Annotation annotation,
 Method method)
