Jakarta EE 11.0.0 · jakarta.enterprise.lang.model.AnnotationInfo

An annotation instance, typically obtained from an AnnotationTarget. Provides access to annotation members and their values.

Implementations of this interface are required to define the equals and hashCode methods. Implementations of this interface are encouraged to define the toString method such that it returns a text resembling the corresponding Java™ syntax.

There is no guarantee that any particular annotation instance, represented by an implementation of this interface, will always be represented by the same object. That includes natural singletons such as the jakarta.inject.Singleton annotation. Instances should always be compared using equals.

Method Summary

Modifier and Type	Method and Description
public ClassInfo	Returns: the declaration of this annotation's type, never `null` declaration() Returns the declaration of this annotation's type.
public boolean	Returns: `true` if this annotation has a member with given `name`, `false` otherwise hasMember(String member name, must not be `null` name) Returns whether this annotation has a member with given `name`.
public default boolean	Returns: `true` if this annotation has the `value` member, `false` otherwise hasValue() Returns whether this annotation has the `value` member.
public default boolean	Returns: whether this annotation is repeatable isRepeatable() Returns whether this annotation is repeatable.
public AnnotationMember	Returns: value of this annotation's member with given `name` or `null` if such member does not exist member(String member name, must not be `null` name) Returns the value of this annotation's member with given `name`.
public Map<String, AnnotationMember>	Returns: an immutable map of all members of this annotation, never `null` members() Returns all members of this annotation as a map, where the key is the member name and the value is the member value.
public default String	Returns: binary name of this annotation's type, never `null` name() Binary name of this annotation's type, as defined by The Java™ Language Specification; in other words, the annotation type name as returned by `Class#getName()`.
public default AnnotationMember	Returns: value of this annotation's `value` member or `null` if the member does not exist value() Returns the value of this annotation's `value` member.
