Method Details

getNavigableRole

NavigableRole getNavigableRole()

See Also:

• getPartName()

API Note:

Whereas getPartName() is local to this part, NavigableRole can be a compound path

getPartName

String getPartName()

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

getPartMappingType

MappingType getPartMappingType()

The type for this part.

getJavaType

JavaType<?> getJavaType()

The Java type for this part. Generally equivalent to MappingType.getMappedJavaType() relative to getPartMappingType()

isVirtual

default boolean isVirtual()

Whether this model part describes something that physically exists in the domain model.

For example, an entity's discriminator is part of the model, but is not a physical part of the domain model - there is no "discriminator attribute".

Also indicates whether the part is castable to VirtualModelPart

isEntityIdentifierMapping

default boolean isEntityIdentifierMapping()

hasPartitionedSelectionMapping

boolean hasPartitionedSelectionMapping()

createDomainResult

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

Create a DomainResult for a specific reference to this ModelPart.

applySqlSelections

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

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

applySqlSelections

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

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

forEachSelectable

default int forEachSelectable(SelectableConsumer consumer)

A short hand form of forEachSelectable(int, SelectableConsumer), that passes 0 as offset.

forEachSelectable

default int forEachSelectable(int offset,
 SelectableConsumer consumer)

Visits each selectable mapping with the selectable index offset by the given value. Returns the amount of jdbc types that have been visited.

asAttributeMapping

default AttributeMapping asAttributeMapping()

asEntityMappingType

default EntityMappingType asEntityMappingType()

asBasicValuedModelPart

default @Nullable BasicValuedModelPart asBasicValuedModelPart()

breakDownJdbcValues

default int breakDownJdbcValues(Object domainValue,
 ModelPart.JdbcValueConsumer valueConsumer,
 SharedSessionContractImplementor session)

A short hand form of breakDownJdbcValues(Object, int, Object, Object, JdbcValueBiConsumer, SharedSessionContractImplementor), that passes 0 as offset and null for the two values X and Y.

breakDownJdbcValues

<X,
Y> int breakDownJdbcValues(Object domainValue,
 int offset,
 X x,
 Y y,
 ModelPart.JdbcValueBiConsumer<X,Y> valueConsumer,
 SharedSessionContractImplementor session)

Breaks down the domain value to its constituent JDBC values. Think of it as breaking the multi-dimensional array into a visitable flat array. Additionally, it passes through the values X and Y to the consumer. Returns the amount of jdbc types that have been visited.

decompose

default int decompose(Object domainValue,
 ModelPart.JdbcValueConsumer valueConsumer,
 SharedSessionContractImplementor session)

A short hand form of decompose(Object, int, Object, Object, JdbcValueBiConsumer, SharedSessionContractImplementor), that passes 0 as offset and null for the two values X and Y.

decompose

default <X,
Y> int decompose(Object domainValue,
 int offset,
 X x,
 Y y,
 ModelPart.JdbcValueBiConsumer<X,Y> valueConsumer,
 SharedSessionContractImplementor session)

Similar to breakDownJdbcValues(Object, int, Object, Object, JdbcValueBiConsumer, SharedSessionContractImplementor), but this method is supposed to be used for decomposing values for assignment expressions. Returns the amount of jdbc types that have been visited.

findContainingEntityMapping

EntityMappingType findContainingEntityMapping()

areEqual

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