Method Details

getFixture

public Expression getFixture()

getExpressionType

public MappingModelExpressible getExpressionType()

Description copied from interface: Expression

The type for this expression

Specified by:

getExpressionType in interface Expression

accept

public void accept(SqlAstWalker walker)

Specified by:

accept in interface SqlAstNode

createDomainResult

public DomainResult createDomainResult(String resultVariable,
 DomainResultCreationState creationState)

Description copied from interface: DomainResultProducer

Produce the domain query

Specified by:

createDomainResult in interface DomainResultProducer

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

getWhenFragments

public List<CaseSimpleExpression.WhenFragment> getWhenFragments()

getOtherwise

public Expression getOtherwise()

otherwise

public void otherwise(Expression otherwiseExpression)

when

public void when(Expression test,
 Expression result)
