Interface BeanInfo

  • All Known Subinterfaces:
    InterceptorInfo
    public interface BeanInfo
    Beans are:
    • managed beans
    • beans defined by producer methods
    • beans defined by producer fields
    • synthetic beans
    Managed beans are also known as class-based beans, while beans defined by producer methods and producer fields are together also known as producer-based beans.

    Class-based and producer-based beans directly correspond to a declaration in program source code. Synthetic beans don't and are instead defined through other mechanisms, such as extensions.

    • Method Detail

      • scope

        ScopeInfo scope()
        Returns the scope of this bean.
        Returns:
        the scope of this bean, never null

      • types

        java.util.Collection<jakarta.enterprise.lang.model.types.Type> types()
        Returns a collection of all types of this bean.
        Returns:
        immutable collection of bean types, never null

      • qualifiers

        java.util.Collection<jakarta.enterprise.lang.model.AnnotationInfo> qualifiers()
        Returns a collection of this bean's qualifiers, represented as AnnotationInfo.
        Returns:
        immutable collection of qualifiers, never null

      • declaringClass

        jakarta.enterprise.lang.model.declarations.ClassInfo declaringClass()
        Returns the class that declares this bean. In case of a managed bean, also known as class-based bean, that is the bean class directly. In case of a producer method or field, that is the class that declares the producer method or field. Returns null if this bean is synthetic.
        Returns:
        ClassInfo for the class that declares this bean, or null if this bean is synthetic

      • isClassBean

        boolean isClassBean()
        Returns whether this bean is a managed bean, also known as class-based bean.
        Returns:
        whether this bean is a managed bean

      • isProducerMethod

        boolean isProducerMethod()
        Returns whether this bean is defined by a producer method.
        Returns:
        whether this bean is defined by a producer method

      • isProducerField

        boolean isProducerField()
        Returns whether this bean is defined by a producer field.
        Returns:
        whether this bean is defined by a producer field

      • isSynthetic

        boolean isSynthetic()
        Returns whether this bean is synthetic. In other words, whether this bean does not correspond to a declaration in program source code and was created through other means (e.g. using an extension).
        Returns:
        whether this bean is synthetic

      • producerMethod

        jakarta.enterprise.lang.model.declarations.MethodInfo producerMethod()
        Returns the producer method that defines this bean. Returns null if this bean is not defined by a producer method.
        Returns:
        producer method that defines this bean, or null if this bean is not defined by a producer method

      • producerField

        jakarta.enterprise.lang.model.declarations.FieldInfo producerField()
        Returns the producer field that defines this bean. Returns null if this bean is not defined by a producer field.
        Returns:
        producer field that defines this bean, or null if this bean is not defined by a producer field

      • isAlternative

        boolean isAlternative()
        Returns whether this bean is an alternative.
        Returns:
        whether this bean is an alternative

      • priority

        java.lang.Integer priority()
        Returns the priority declared on this bean, or null if this bean does not declare a priority. Declaring a priority on an alternative bean makes it an enabled alternative. Similarly, declaring a priority on an interceptor makes it an enabled interceptor.
        Returns:
        the priority of this bean, or null if this bean does not declare a priority

      • name

        java.lang.String name()
        Returns the bean name of this bean. A bean name is usually defined using the @Named annotation. Returns null if the bean does not have a name.
        Returns:
        the bean name, or null if the bean does not have a name

      • disposer

        DisposerInfo disposer()
        Returns the disposer method of this producer-based bean. Returns null if this bean is not a defined by a producer method or a producer field, or if this producer-based bean does not have a corresponding disposer method.
        Returns:
        the disposer, or null if this bean does not have a disposer

      • stereotypes

        java.util.Collection<StereotypeInfo> stereotypes()
        Returns a collection of this bean's stereotypes.
        Returns:
        immutable collection of stereotypes, never null

      • injectionPoints

        java.util.Collection<InjectionPointInfo> injectionPoints()
        Returns a collection of this bean's injection points.
        Returns:
        immutable collection of injection points, never null

      • isInterceptor

        default boolean isInterceptor()
        Returns whether this bean is an interceptor.
        Returns:
        whether this bean is an interceptor

      • asInterceptor

        default InterceptorInfo asInterceptor()
        Returns this bean as an interceptor.
        Returns:
        this interceptor, never null
        Throws:
        java.lang.IllegalStateException - if isInterceptor() returns false
