Method Details

getEntityMappingType

EntityMappingType getEntityMappingType()

The descriptor of the entity that is the type for this part

findSubPart

default ModelPart findSubPart(String name)

forEachSubPart

default void forEachSubPart(org.hibernate.internal.util.IndexedConsumer<ModelPart> consumer,
 EntityMappingType treatTarget)

Specified by:

forEachSubPart in interface ModelPartContainer

findSubPart

default ModelPart findSubPart(String name,
 EntityMappingType targetType)

Specified by:

findSubPart in interface ModelPartContainer

visitSubParts

default void visitSubParts(Consumer<ModelPart> consumer,
 EntityMappingType targetType)

Specified by:

visitSubParts in interface ModelPartContainer

createDomainResult

default <T> DomainResult<T> createDomainResult(NavigablePath navigablePath,
 TableGroup tableGroup,
 String resultVariable,
 DomainResultCreationState creationState)

Description copied from interface: ModelPart

Create a DomainResult for a specific reference to this ModelPart.

Specified by:

createDomainResult in interface ModelPart

applySqlSelections

default void applySqlSelections(NavigablePath navigablePath,
 TableGroup tableGroup,
 DomainResultCreationState creationState)

Description copied from interface: ModelPart

Apply SQL selections for a specific reference to this ModelPart outside the domain query's root select clause.

Specified by:

applySqlSelections in interface ModelPart

applySqlSelections

default void applySqlSelections(NavigablePath navigablePath,
 TableGroup tableGroup,
 DomainResultCreationState creationState,
 BiConsumer<SqlSelection,JdbcMapping> selectionConsumer)

Description copied from interface: ModelPart

Apply SQL selections for a specific reference to this ModelPart outside the domain query's root select clause.

Specified by:

applySqlSelections in interface ModelPart

getJdbcTypeCount

default int getJdbcTypeCount()

Description copied from interface: Bindable

The number of JDBC mappings

Specified by:

getJdbcTypeCount in interface Bindable

Specified by:

getJdbcTypeCount in interface JdbcMappingContainer

forEachJdbcType

default int forEachJdbcType(int offset,
 org.hibernate.internal.util.IndexedConsumer<JdbcMapping> action)

Description copied from interface: JdbcMappingContainer

Visit each JdbcMapping starting from the given offset

Specified by:

forEachJdbcType in interface JdbcMappingContainer

disassemble

default 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

addToCacheKey

default void addToCacheKey(MutableCacheKeyBuilder cacheKey,
 Object value,
 SharedSessionContractImplementor session)

Description copied from interface: Bindable

Add to the MutableCacheKey the values obtained disassembling the value and the hasCode generated from the disassembled value.

Specified by:

addToCacheKey in interface Bindable

Parameters:

cacheKey - the MutableCacheKey used to add the disassembled value and the hashCode

value - the value to disassemble

session - the SharedSessionContractImplementor

forEachDisassembledJdbcValue

default <X,
Y> int forEachDisassembledJdbcValue(Object value,
 int offset,
 X x,
 Y y,
 Bindable.JdbcValuesBiConsumer<X,Y> valuesConsumer,
 SharedSessionContractImplementor session)

Description copied from interface: Bindable

Like Bindable.forEachDisassembledJdbcValue(Object, Object, Object, JdbcValuesBiConsumer, SharedSessionContractImplementor), but additionally receives an offset by which the selectionIndex is incremented when calling Bindable.JdbcValuesBiConsumer.consume(int, Object, Object, Object, JdbcMapping).

Specified by:

forEachDisassembledJdbcValue in interface Bindable

forEachJdbcValue

default <X,
Y> int forEachJdbcValue(Object value,
 int offset,
 X x,
 Y y,
 Bindable.JdbcValuesBiConsumer<X,Y> consumer,
 SharedSessionContractImplementor session)

Description copied from interface: Bindable

Visit each constituent JDBC value extracted from the entity instance itself. Short-hand form of calling Bindable.disassemble(java.lang.Object, org.hibernate.engine.spi.SharedSessionContractImplementor) and piping its result to Bindable.forEachDisassembledJdbcValue(Object, int, JdbcValuesConsumer, SharedSessionContractImplementor)

forEachJdbcValue in interface Bindable
