Method Detail

getPartName

default String getPartName()

Description copied from interface: ModelPart

The local part name, which is generally the unqualified role name

Specified by:

getPartName in interface ModelPart

getNature

EntityIdentifierMapping.Nature getNature()

See Also:

EntityIdentifierMapping.Nature

getAttributeName

String getAttributeName()

The name of the attribute defining the id, if one

getUnsavedStrategy

IdentifierValue getUnsavedStrategy()

The strategy for distinguishing between detached and transient state based on the identifier mapping

See Also:

EntityVersionMapping.getUnsavedStrategy()

instantiate

Object instantiate()

Instantiate an instance of the identifier.

getIdentifier

Object getIdentifier(Object entity)

Extract the identifier from an instance of the entity

getIdentifierIfNotUnsaved

default Object getIdentifierIfNotUnsaved(Object entity,
                                         SharedSessionContractImplementor session)

Return the identifier of the persistent or transient object, or throw an exception if the instance is "unsaved"

Used by OneToOneType and ManyToOneType to determine what id value should be used for an object that may or may not be associated with the session. This does a "best guess" using any/all info available to use (not just the EntityEntry).

Parameters:

entity - The entity instance

session - The session

Returns:

The identifier

Throws:

TransientObjectException - if the entity is transient (does not yet have an identifier)

Since:

6.1.1

ForeignKeys.getEntityIdentifierIfNotUnsaved(String, Object, SharedSessionContractImplementor)

setIdentifier

void setIdentifier(Object entity,
                   Object id,
                   SharedSessionContractImplementor session)

Inject an identifier value into an instance of the entity
