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.

getBeanConfiguration

public <T> BeanConfiguration<T> getBeanConfiguration(Class<T> beanClass)

findConstraintAnnotations

protected <A extends Annotation>
List<ConstraintDescriptorImpl<?>> findConstraintAnnotations(Constrainable constrainable,
 A annotation,
 ConstraintLocation.ConstraintLocationKind type)

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

Type Parameters:

A - the annotation type

Parameters:

constrainable - The constrainable 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.

findTypeAnnotationConstraints

protected Set<MetaConstraint<?>> findTypeAnnotationConstraints(JavaBeanField javaBeanField)

Finds type arguments constraints for fields.

findTypeAnnotationConstraints

protected Set<MetaConstraint<?>> findTypeAnnotationConstraints(JavaBeanExecutable<?> javaBeanExecutable)

Finds type arguments constraints for method return values.

findTypeAnnotationConstraintsForExecutableParameter

protected Set<MetaConstraint<?>> findTypeAnnotationConstraintsForExecutableParameter(JavaBeanExecutable<?> javaBeanExecutable,
 JavaBeanParameter javaBeanParameter)

Finds type arguments constraints for parameters.

Parameters:

javaBeanParameter - the parameter

Returns:

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