Interface CascadingMetaData

All Known Implementing Classes:

ContainerCascadingMetaData, NonContainerCascadingMetaData, PotentiallyContainerCascadingMetaData

public interface CascadingMetaData

An aggregated view of the cascading validation metadata. Note that it also includes the cascading validation metadata defined on the root element via the ArrayElement and AnnotatedObject pseudo type parameters.

To reduce the memory footprint, CascadingMetaData comes in 2 variants:

• NonContainerCascadingMetaData dedicated to non containers: it is very lightweight;
• ContainerCascadingMetaData used for containers: it is the full featured version.

Method Summary

Modifier and Type	Method and Description
CascadingMetaData	addRuntimeContainerSupport(ValueExtractorManager valueExtractorManager, Class<?> valueClass) Add additional cascading metadata when: the element is marked with @Valid, the runtime type of the element is container based (e.g.
<T extends CascadingMetaData> T	as(Class<T> clazz)
Class<?>	convertGroup(Class<?> originalGroup)
Set<GroupConversionDescriptor>	getGroupConversionDescriptors()
TypeVariable<?>	getTypeParameter()
boolean	isCascading()
boolean	isContainer()
boolean	isMarkedForCascadingOnAnnotatedObjectOrContainerElements()

addRuntimeContainerSupport

CascadingMetaData addRuntimeContainerSupport(ValueExtractorManager valueExtractorManager,
                                             Class<?> valueClass)

Add additional cascading metadata when:

• the element is marked with @Valid,
• the runtime type of the element is container based (e.g. collections, maps or arrays),
• and there are ValueExtractors present for such container,
• and the declared type isn't container based.

An example of this particular situation is: @Valid private Object element = new ArrayList<String>().

Note that if the declared type is container based, the cascading information is directly included at bootstrap time.
