Class PropertyMetaData

java.lang.Object

org.hibernate.validator.internal.metadata.aggregated.AbstractConstraintMetaData

org.hibernate.validator.internal.metadata.aggregated.PropertyMetaData

All Implemented Interfaces:

Iterable<MetaConstraint<?>>, ConstraintMetaData, Cascadable

public class PropertyMetaData
extends AbstractConstraintMetaData
implements Cascadable

Represents the constraint related meta data for a JavaBeans property. Abstracts from the concrete physical type of the underlying Java element(s) (fields or getter methods).

In order to provide a unified access to all JavaBeans constraints also class-level constraints are represented by this meta data type.

Identity is solely based on the property name, hence sets and similar collections of this type may only be created in the scope of one Java type.

Method Detail

getElementType

public ElementType getElementType()

Description copied from interface: Cascadable

Returns the element type of the cascadable.

Specified by:

getElementType in interface Cascadable

Returns:

Returns the element type of the cascadable.

convertGroup

public Class<?> convertGroup(Class<?> from)

Description copied from interface: Cascadable

Converts the given validation group as per the group conversion configuration for this element (as e.g. specified via @ConvertGroup.

Specified by:

convertGroup in interface Cascadable

Parameters:

from - The group to convert.

Returns:

The converted group. Will be the original group itself in case no conversion is to be performed.

getGroupConversionDescriptors

public Set<GroupConversionDescriptor> getGroupConversionDescriptors()

Description copied from interface: Cascadable

Returns a set with GroupConversionDescriptors representing the group conversions of this cascadable.

Specified by:

getGroupConversionDescriptors in interface Cascadable

Returns:

A set with group conversion descriptors. May be empty, but never null.

getTypeArgumentsConstraints

public Set<MetaConstraint<?>> getTypeArgumentsConstraints()

Description copied from interface: Cascadable

Returns the type arguments constraints for this cascadable.

Specified by:

getTypeArgumentsConstraints in interface Cascadable

Returns:

the type arguments constraints for this cascadable, or an empty set if no constrained type arguments are found

asDescriptor

public PropertyDescriptorImpl asDescriptor(boolean defaultGroupSequenceRedefined,
                                           List<Class<?>> defaultGroupSequence)

Description copied from interface: ConstraintMetaData

Returns this meta data object's corresponding representation in the descriptor model.

Specified by:

asDescriptor in interface ConstraintMetaData

Parameters:

defaultGroupSequenceRedefined - Whether the bean hosting the represented element has a redefined default group sequence or not.

defaultGroupSequence - The default group sequence of the bean hosting the represented element.

Returns:

This meta data object's corresponding descriptor model representation. Implementations should return a specific sub type of ElementDescriptor.

getValue

public Object getValue(Object parent)

Description copied from interface: Cascadable

Returns the value of this cacadable from the given parent.

Specified by:

getValue in interface Cascadable

getCascadableType

public Type getCascadableType()

Description copied from interface: Cascadable

Returns the data type of this cascadable, e.g. the type of a bean property or the return type of a method.

Specified by:

getCascadableType in interface Cascadable

Returns:

This cascadable type.

toString

public String toString()

Overrides:

toString in class AbstractConstraintMetaData

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractConstraintMetaData

equals

public boolean equals(Object obj)

Overrides:

equals in class AbstractConstraintMetaData
