Interface ConstrainedElement

All Superinterfaces:

Iterable<MetaConstraint<?>>

All Known Implementing Classes:

AbstractConstrainedElement, ConstrainedExecutable, ConstrainedField, ConstrainedParameter, ConstrainedType

public interface ConstrainedElement
extends Iterable<MetaConstraint<?>>

Represents a (potentially) constrained Java element such as a type, field or method. Such an element has a set of MetaConstraints and can be marked for a cascaded validation. Furthermore each constrained element has a configuration source which determines its origin.

The hierarchy of constrained elements resembles the physical structure of the represented Java types. In particular it doesn't provide the notion of properties and it doesn't aggregate meta data for overridden elements in an inheritance hierarchy.

Identity of implementations is based on the element location and constraint source. That means that for instance in a set there can be two configurations for one and the same Java field created by two different configuration sources (e.g. via annotation and XML) but not two configurations for the same field originating from one configuration source.

Implementations are strictly read-only.

Method Detail

getKind

ConstrainedElement.ConstrainedElementKind getKind()

Returns the kind of this constrained element.

Returns:

The kind of this constrained element.

getLocation

ConstraintLocation getLocation()

Returns the location of this constrained element.

Returns:

The location of this constrained element.

getConstraints

Set<MetaConstraint<?>> getConstraints()

Returns a set containing the constraints specified for this constrained element.

Returns:

A set with this constrained element's constraints. May be empty, but never null.

getGroupConversions

Map<Class<?>,Class<?>> getGroupConversions()

Returns a map with the group conversions for this constrained element, as e.g. given using the @ConvertGroup annotation.

Returns:

A map with this constrained element's group conversions. May be empty, but never null.

isCascading

boolean isCascading()

Whether cascading validation for the represented element shall be performed or not.

Returns:

True, if cascading validation for the represented element shall be performed, false otherwise.

isConstrained

boolean isConstrained()

Whether this element is constrained or not. This is the case, if this element has at least one constraint or a cascaded validation shall be performed for it.

Returns:

True, if this element is constrained, false otherwise.
