findConstraintAnnotations

protected <A extends java.lang.annotation.Annotation> java.util.List<ConstraintDescriptorImpl<?>> findConstraintAnnotations(java.lang.reflect.Member member,
                                                                                                                            A annotation,

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.

findTypeAnnotationConstraints

protected java.util.Set<MetaConstraint<?>> findTypeAnnotationConstraints(java.lang.reflect.Field field)

Finds type arguments constraints for fields.

findTypeAnnotationConstraints

Finds type arguments constraints for parameters.

Parameters:

executable - the executable

i - the parameter index

Returns:
