Method Detail

getAnnotationDescriptor

public ConstraintAnnotationDescriptor<T> getAnnotationDescriptor()

getAnnotation

public T getAnnotation()

Description copied from interface: ConstraintDescriptor

Returns the annotation describing the constraint declaration. If a composing constraint, attribute values are reflecting the overridden attributes of the composing constraint

Specified by:

getAnnotation in interface ConstraintDescriptor<T extends Annotation>

Returns:

the annotation for this constraint

getAnnotationType

public Class<T> getAnnotationType()

getMessageTemplate

public String getMessageTemplate()

Description copied from interface: ConstraintDescriptor

The non-interpolated error message

Specified by:

getMessageTemplate in interface ConstraintDescriptor<T extends Annotation>

Returns:

the non-interpolated error message

getGroups

public Set<Class<?>> getGroups()

Description copied from interface: ConstraintDescriptor

The set of groups the constraint is applied on. If the constraint declares no group, a set with only the Default group is returned.

Specified by:

getGroups in interface ConstraintDescriptor<T extends Annotation>

Returns:

the groups the constraint is applied on

getPayload

public Set<Class<? extends Payload>> getPayload()

Description copied from interface: ConstraintDescriptor

The set of payload the constraint hosts.

Specified by:

getPayload in interface ConstraintDescriptor<T extends Annotation>

Returns:

payload classes hosted on the constraint or an empty set if none

getValidationAppliesTo

public ConstraintTarget getValidationAppliesTo()

Description copied from interface: ConstraintDescriptor

The ConstraintTarget value of validationAppliesTo if the constraint hosts it or null otherwise.

Specified by:

getValidationAppliesTo in interface ConstraintDescriptor<T extends Annotation>

Returns:

the ConstraintTarget value or null

getValueUnwrapping

public ValidateUnwrappedValue getValueUnwrapping()

Specified by:

getValueUnwrapping in interface ConstraintDescriptor<T extends Annotation>

Returns:

a ValidateUnwrappedValue describing the unwrapping behavior as given via the Unwrapping constraint payloads.

getConstraintValidatorClasses

public List<Class<? extends ConstraintValidator<T,?>>> getConstraintValidatorClasses()

Description copied from interface: ConstraintDescriptor

List of the constraint validation implementation classes.

Specified by:

getConstraintValidatorClasses in interface ConstraintDescriptor<T extends Annotation>

Returns:

list of the constraint validation implementation classes

getMatchingConstraintValidatorDescriptors

public List<ConstraintValidatorDescriptor<T>> getMatchingConstraintValidatorDescriptors()

Return all constraint validator descriptors (either generic or cross-parameter) which are registered for the constraint of this descriptor.

Returns:

The constraint validator descriptors applying to type of this constraint.

getAttributes

public Map<String,Object> getAttributes()

Description copied from interface: ConstraintDescriptor

Returns a map containing the annotation attribute names as keys and the annotation attribute values as value.

If this constraint is used as part of a composed constraint, attribute values are reflecting the overridden attribute of the composing constraint.

Specified by:

getAttributes in interface ConstraintDescriptor<T extends Annotation>

Returns:

a map containing the annotation attribute names as keys and the annotation attribute values as value

getComposingConstraints

public Set<ConstraintDescriptor<?>> getComposingConstraints()

Description copied from interface: ConstraintDescriptor

Return a set of composing ConstraintDescriptors where each descriptor describes a composing constraint. ConstraintDescriptor instances of composing constraints reflect overridden attribute values in ConstraintDescriptor.getAttributes() and ConstraintDescriptor.getAnnotation().

Specified by:

getComposingConstraints in interface ConstraintDescriptor<T extends Annotation>

Returns:

a set of ConstraintDescriptor objects or an empty set in case there are no composing constraints

getComposingConstraintImpls

public Set<ConstraintDescriptorImpl<?>> getComposingConstraintImpls()

isReportAsSingleViolation

public boolean isReportAsSingleViolation()

Specified by:

isReportAsSingleViolation in interface ConstraintDescriptor<T extends Annotation>

Returns:

true if the constraint is annotated with ReportAsSingleViolation

getElementType

public ElementType getElementType()

getDefinedOn

public ConstraintOrigin getDefinedOn()

getConstraintType

public ConstraintDescriptorImpl.ConstraintType getConstraintType()

unwrap

public <U> U unwrap(Class<U> type)

Description copied from interface: ConstraintDescriptor

Returns an instance of the specified type allowing access to provider-specific APIs.

If the Bean Validation provider implementation does not support the specified class, a ValidationException is thrown.

Specified by:

unwrap in interface ConstraintDescriptor<T extends Annotation>

Type Parameters:

U - the type of the object to be returned

Parameters:

type - the class of the object to be returned

Returns:

an instance of the specified class

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

getCompositionType

public CompositionType getCompositionType()

Returns:

the compositionType
