Method Detail

accepts

public abstract boolean accepts(ConstrainedElement constrainedElement)

Whether this builder allows to add the given element or not. This is the case if the specified element relates to the same property or method with which this builder was instantiated.

Parameters:

constrainedElement - The element to check.

Returns:

true if the given element can be added to this builder, false otherwise.

add

public void add(ConstrainedElement constrainedElement)

Adds the given element to this builder. It must be checked with accepts(ConstrainedElement) before, whether this is allowed or not.

Parameters:

constrainedElement - The element to add.

build

public abstract ConstraintMetaData build()

Creates a new, read-only ConstraintMetaData object with all constraint information related to the method or property represented by this builder.

Returns:

A ConstraintMetaData object.

getGroupConversions

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

getConstraints

protected Set<MetaConstraint<?>> getConstraints()

isCascading

protected boolean isCascading()

adaptOriginsAndImplicitGroups

protected Set<MetaConstraint<?>> adaptOriginsAndImplicitGroups(Class<?> beanClass,
                                                   Set<MetaConstraint<?>> constraints)

Adapts the given constraints to the given bean type. In case a constraint is defined locally at the bean class the original constraint will be returned without any modifications. If a constraint is defined in the hierarchy (interface or super class) a new constraint will be returned with an origin of ConstraintOrigin.DEFINED_IN_HIERARCHY. If a constraint is defined on an interface, the interface type will additionally be part of the constraint's groups (implicit grouping).

Parameters:

beanClass - The bean type to which the constraint shall be adapted.

constraints - The constraints that shall be adapted. The constraints themselves will not be altered.

Returns:

A constraint adapted to the given bean type.
