Method Detail

getIndex

public int getIndex()

convertGroup

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

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:

originalGroup - 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.

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.

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 ParameterDescriptor 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.
