Method Summary

Modifier and TypeMethod and Description
public void
cascade(EventSource
The session within which the cascade is occurring.
session, Object
The child to which cascading should be performed.
child, String
The child's entity name
entityName, Object
Anything ;) Typically some form of cascade-local cache which is specific to each CascadingAction type
anything, boolean
Are cascading deletes enabled.
isCascadeDeleteEnabled)

Deprecated as a consequence of EventSource being deprecated.
Cascade the action to the child object.
public boolean

Returns:

True if this action can lead to deletions of orphans.
deleteOrphans()

Does this action potentially extrapolate to orphan deletes?

public Iterator<E>

Returns:

The children iterator.
getCascadableChildrenIterator(EventSource
The session within which the cascade is occurring.
session, CollectionType
The mapping type of the collection.
collectionType, Object
The collection instance.
collection)

Deprecated as a consequence of EventSource being deprecated.
Given a collection, get an iterator of the children upon which the current cascading action should be visited.
public void
noCascade(EventSource
The session within which the cascade is occurring.
session, Object
The property value owner
parent, EntityPersister
The entity persister for the owner
persister, Type
The property type
propertyType, int
The index of the property within the owner.
propertyIndex)

Deprecated as a consequence of EventSource being deprecated.
Called (in the case of requiresNoCascadeChecking returning true) to validate that no cascade on the given property is considered a valid semantic.
public boolean
performOnLazyProperty()

Should this action be performed (or noCascade consulted) in the case of lazy properties.

public boolean

Returns:

True if this action requires no-cascade verification; false otherwise.
requiresNoCascadeChecking()

Does the specified cascading action require verification of no cascade validity?

Method Detail

public Iterator<E> getCascadableChildrenIterator(EventSource session, CollectionType collectionType, Object collection)

Deprecated

as a consequence of EventSource being deprecated. See corresponding docs for further information.

Returns:Iterator<E>

The children iterator.

noCascadeback to summary
public void noCascade(EventSource session, Object parent, EntityPersister persister, Type propertyType, int propertyIndex)

Deprecated

as a consequence of EventSource being deprecated. See corresponding docs for further information.

Called (in the case of requiresNoCascadeChecking returning true) to validate that no cascade on the given property is considered a valid semantic.

Parameters

The session within which the cascade is occurring.

parent:Object

The property value owner

persister:EntityPersister

The entity persister for the owner

propertyType:Type

The property type
