Specified by:

createSqlSelection in interface Expression

Specified by:

createSqlSelection in interface SqlSelectionProducer

Parameters:

jdbcPosition - The index position used to read values from JDBC

valuesArrayPosition - The position in our "current JDBC values array"

javaType - The descriptor for the Java type to read the value as

virtual - Whether the select is virtual or real. See SqlSelection.isVirtual()

typeConfiguration - The associated TypeConfiguration

createDomainResultSqlSelection

createDomainResultSqlSelection in interface Expression

accept

public void accept(SqlAstWalker sqlTreeWalker)

Specified by:

accept in interface SqlAstNode

createDomainResult

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

Description copied from interface: DomainResultProducer

Produce the domain query

Specified by:

createDomainResult in interface DomainResultProducer<B>

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<B>
