Constructor Detail

AnnotationMetaDataProvider

public AnnotationMetaDataProvider(ConstraintHelper constraintHelper,
                                  ParameterNameProvider parameterNameProvider,
                                  AnnotationProcessingOptions annotationProcessingOptions)

Method Detail

getAnnotationProcessingOptions

public AnnotationProcessingOptions getAnnotationProcessingOptions()

Description copied from interface: MetaDataProvider

Returns the annotation processing options as configured by this provider.

Specified by:

getAnnotationProcessingOptions in interface MetaDataProvider

Returns:

The annotation processing options as configured by this provider.

getBeanConfigurationForHierarchy

public <T> List<BeanConfiguration<? super T>> getBeanConfigurationForHierarchy(Class<T> beanClass)

Description copied from interface: MetaDataProvider

Returns a list with the configurations for all types contained in the given type's hierarchy (including implemented interfaces) starting at the specified type.

Specified by:

getBeanConfigurationForHierarchy in interface MetaDataProvider

Type Parameters:

T - The type of the class to get the configurations for.

Parameters:

beanClass - The type of interest.

Returns:

A set with the configurations for the complete hierarchy of the given type. May be empty, but never null.

findConstraintAnnotations

protected <A extends Annotation> List<ConstraintDescriptorImpl<?>> findConstraintAnnotations(Member member,
                                                                                             A annotation,
                                                                                             ElementType type)

Examines the given annotation to see whether it is a single- or multi-valued constraint annotation.

Type Parameters:

A - the annotation type

Parameters:

member - The member to check for constraints annotations

annotation - The annotation to examine

type - the element type on which the annotation/constraint is placed on

Returns:

A list of constraint descriptors or the empty list in case annotation is neither a single nor multi-valued annotation.

findTypeAnnotationConstraintsForMember

protected Set<MetaConstraint<?>> findTypeAnnotationConstraintsForMember(Member member)

Finds type arguments constraints for fields and methods return values.

Parameters:

member - the field or method

Returns:

a set of type arguments constraints, or an empty set if no constrained type arguments are found

findTypeAnnotationConstraintsForExecutableParameter

protected Set<MetaConstraint<?>> findTypeAnnotationConstraintsForExecutableParameter(Member member,
                                                                                     int i)

Finds type arguments constraints for parameters.

Parameters:

member - the method

i - the parameter index

Returns:

a set of type arguments constraints, or an empty set if no constrained type arguments are found
