Method Detail

getElementValidator

@Nullable
public AnnotatedElementValidator getElementValidator()

The AnnotatedElementValidator instance. Can be null.

Returns:

The validator instance

hasStereotype

protected boolean hasStereotype(Element element,
                                Class<? extends Annotation> stereotype)

Return whether the given element is annotated with the given annotation stereotype.

Parameters:

element - The element

stereotype - The stereotype

Returns:

True if it is

hasStereotype

protected boolean hasStereotype(Element element,
                                String... stereotypes)

Return whether the given element is annotated with the given annotation stereotypes.

Parameters:

element - The element

stereotypes - The stereotypes

Returns:

True if it is

hasStereotype

protected boolean hasStereotype(Element element,
                                List<String> stereotypes)

Return whether the given element is annotated with any of the given annotation stereotypes.

Parameters:

element - The element

stereotypes - The stereotypes

Returns:

getAnnotationMetadata

public AnnotationMetadata getAnnotationMetadata(Element element)

Get the annotation metadata for the given element.

Parameters:

element - The element

Returns:

The AnnotationMetadata

getDeclaredAnnotationMetadata

public AnnotationMetadata getDeclaredAnnotationMetadata(Element element)

Get the declared annotation metadata for the given element.

Parameters:

element - The element

Returns:

The AnnotationMetadata

getAnnotationMetadata

public AnnotationMetadata getAnnotationMetadata(Element parent,
                                                Element element)

Get the annotation metadata for the given element and the given parent. This method is used for cases when you need to combine annotation metadata for two elements, for example a JavaBean property where the field and the method metadata need to be combined.

Parameters:
