Interface ConstraintDescriptor<T extends Annotation>

public interface ConstraintDescriptor<T extends Annotation>
Describes a single constraint and its composing constraints.

T is the constraint's annotation type.

  • Method Details

    • getAnnotation

      T getAnnotation()
      Returns the annotation describing the constraint declaration. If a composing constraint, attribute values are reflecting the overridden attributes of the composing constraint
      Returns:
      the annotation for this constraint

    • getMessageTemplate

      String getMessageTemplate()
      The non-interpolated error message
      Returns:
      the non-interpolated error message
      Since:
      1.1

    • getGroups

      Set<Class<?>> getGroups()
      The set of groups the constraint is applied on. If the constraint declares no group, a set with only the Default group is returned.
      Returns:
      the groups the constraint is applied on

    • getPayload

      Set<Class<? extends Payload>> getPayload()
      The set of payload the constraint hosts.
      Returns:
      payload classes hosted on the constraint or an empty set if none

    • getValidationAppliesTo

      ConstraintTarget getValidationAppliesTo()
      The ConstraintTarget value of validationAppliesTo if the constraint hosts it or null otherwise.
      Returns:
      the ConstraintTarget value or null
      Since:
      1.1

    • getConstraintValidatorClasses

      List<Class<? extends ConstraintValidator<T,?>>> getConstraintValidatorClasses()
      List of the constraint validation implementation classes.
      Returns:
      list of the constraint validation implementation classes

    • getAttributes

      Map<String,Object> getAttributes()
      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.

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

    • getComposingConstraints

      Set<ConstraintDescriptor<?>> getComposingConstraints()
      Return a set of composing ConstraintDescriptors where each descriptor describes a composing constraint. ConstraintDescriptor instances of composing constraints reflect overridden attribute values in getAttributes() and getAnnotation().
      Returns:
      a set of ConstraintDescriptor objects or an empty set in case there are no composing constraints

    • isReportAsSingleViolation

      boolean isReportAsSingleViolation()
      Returns:
      true if the constraint is annotated with ReportAsSingleViolation
