@Internal
public class BeanDefinitionWriter
extends AbstractClassFileWriter
implements BeanDefinitionVisitor, BeanElement, Toggleable

Responsible for building BeanDefinition instances at compile time. Uses ASM build the class definition.

Should be used from AST frameworks to build bean definitions from source code data.

For example:

     

          BeanDefinitionWriter writer = new BeanDefinitionWriter("my.package", "MyClass", "jakarta.inject.Singleton", true)
          writer.visitBeanDefinitionConstructor()
          writer.visitFieldInjectionPoint("my.Qualifier", false, "my.package.MyDependency", "myfield" )
          writer.visitBeanDefinitionEnd()
          writer.writeTo(new File(..))

annotate

public <T extends Annotation> Element annotate(String annotationType,
 Consumer<AnnotationValueBuilder<T>> consumer)

Description copied from interface: MutableAnnotationMetadataDelegate

Annotate this element with the given annotation type. If the annotation is already present then any values populated by the builder will be merged/overridden with the existing values.

Specified by:

annotate in interface Element

Specified by:

annotate in interface MutableAnnotationMetadataDelegate<Element>

Type Parameters:

T - The annotation generic type

Parameters:

annotationType - The annotation type

consumer - A function that receives the AnnotationValueBuilder

This element

removeAnnotation

public Element removeAnnotation(String annotationType)

Description copied from interface: MutableAnnotationMetadataDelegate

Removes an annotation of the given type from the element.

predicate - The predicate

Returns:

This element

Removes a stereotype of the given name from the element.

Specified by:

removeStereotype in interface Element

Specified by:

removeStereotype in interface MutableAnnotationMetadataDelegate<Element>

Parameters:

annotationType - The annotation type

Returns:

This element

getDeclaringClass
