getPartMappingType in interface CompositeIdentifierMapping

Specified by:

getPartMappingType in interface ModelPart

getIdClassEmbeddable

public IdClassEmbeddable getIdClassEmbeddable()

Description copied from interface: NonAggregatedIdentifierMapping

The id-class representation of this id mapping

Specified by:

getVirtualIdEmbeddable

public VirtualIdEmbeddable getVirtualIdEmbeddable()

Description copied from interface: NonAggregatedIdentifierMapping

The virtual-id representation of this id mapping

Specified by:

getVirtualIdEmbeddable in interface NonAggregatedIdentifierMapping

getIdentifierValueMapper

public NonAggregatedIdentifierMapping.IdentifierValueMapper getIdentifierValueMapper()

Description copied from interface: NonAggregatedIdentifierMapping

The id-class, if there is one, otherwise the virtual-id.

Specified by:

hasContainingClass

public boolean hasContainingClass()

Description copied from interface: CompositeIdentifierMapping

Does the identifier have a corresponding EmbeddableId or IdClass?

Specified by:

hasContainingClass in interface CompositeIdentifierMapping

Overrides:

hasContainingClass in class AbstractCompositeIdentifierMapping

Returns:

false if there is not an IdCass or an EmbeddableId

getMappedIdEmbeddableTypeDescriptor

public EmbeddableMappingType getMappedIdEmbeddableTypeDescriptor()

Description copied from interface: CompositeIdentifierMapping

Returns the embeddable type descriptor of the id-class, if there is one, otherwise the one of the virtual embeddable mapping type.

Specified by:

getMappedIdEmbeddableTypeDescriptor in interface CompositeIdentifierMapping

areEqual

public boolean areEqual(@Nullable Object one,
 @Nullable Object other,
 SharedSessionContractImplementor session)

Specified by:

areEqual in interface ModelPart

disassemble

public Object disassemble(Object value,
 SharedSessionContractImplementor session)

Description copied from interface: Bindable

Breaks down a value of J into its simple pieces. E.g., an embedded value gets broken down into an array of its attribute state; a basic value converts to itself; etc.

Generally speaking, this is the form in which entity state is kept relative to a Session via EntityEntry.

 @Entity class Person {
     @Id Integer id;
     @Embedded Name name;
     int age;
 }

 @Embeddable class Name {
     String familiarName;
     String familyName;
 }
 

At the top level, we would want to disassemble a Person value, so we'd ask the Bindable for the Person entity to disassemble. Given a Person value:

 Person( id=1, name=Name( 'Steve', 'Ebersole' ), 28 )
 

this disassemble would result in a multidimensional array:

 [ ["Steve", "Ebersole"], 28 ]
 

Note that the identifier is not part of this disassembled state. Note also how the embedded value results in a sub-array.

Specified by:

disassemble in interface Bindable

Specified by:

disassemble in interface EmbeddableValuedModelPart
