 EmbeddableValuedModelPart mapping,
 SqlTuple sqlExpression)

Method Details

getExpressionType

public ModelPart getExpressionType()

Description copied from interface: Expression

The type for this expression

Specified by:

getExpressionType in interface Expression

createDomainResult

public DomainResult<T> createDomainResult(String resultVariable,
 DomainResultCreationState creationState)

Description copied from interface: DomainResultProducer

Produce the domain query

Specified by:

createDomainResult in interface DomainResultProducer<T>

applySqlSelections

public void applySqlSelections(DomainResultCreationState creationState)

Description copied from interface: DomainResultProducer

Used when this producer is a selection in a sub-query. The DomainResult is only needed for root query of a SELECT statement. This default impl assumes this producer is a true (Sql)Expression

Specified by:

applySqlSelections in interface DomainResultProducer<T>

visitColumnReferences

public void visitColumnReferences(Consumer<ColumnReference> columnReferenceConsumer)

Specified by:

visitColumnReferences in interface Assignable

getColumnReferences

public List<ColumnReference> getColumnReferences()

Specified by:

getColumnReferences in interface Assignable

getSqlTuple

public SqlTuple getSqlTuple()

Specified by:

getSqlTuple in interface SqlTupleContainer

accept

public void accept(SqlAstWalker sqlTreeWalker)

Specified by:

accept in interface SqlAstNode
