Method Summary

Modifier and Type	Method	Description
void	applySqlSelections(DomainResultCreationState creationState)	Used when this producer is a selection in a sub-query.
DomainResult<T>	createDomainResult(String resultVariable, DomainResultCreationState creationState)	Produce the domain query
SqlSelection	createSqlSelection(int jdbcPosition, int valuesArrayPosition, JavaType javaType, boolean virtual, TypeConfiguration typeConfiguration)	Create a SqlSelection for the given JDBC ResultSet position

List<? extends SqlAstNode>	getArguments()
JdbcMappingContainer	getExpressionType()	The type for this expression
String	getFunctionName()
JdbcMapping	getJdbcMapping()	Anything that is expressible at the SQL AST level would be of basic type.

Constructor Details

SelfRenderingFunctionSqlAstExpression

public SelfRenderingFunctionSqlAstExpression(String functionName,
 FunctionRenderer renderer,
 List<? extends SqlAstNode> sqlAstArguments,
 @Nullable ReturnableType<T> type,
 @Nullable JdbcMappingContainer expressible)

Method Details

getFunctionName

public String getFunctionName()

Specified by:

getFunctionName in interface FunctionExpression

getArguments

public List<? extends SqlAstNode> getArguments()

Specified by:

getArguments in interface FunctionExpression

getExpressionType

public JdbcMappingContainer getExpressionType()

Description copied from interface: Expression

The type for this expression

Specified by:

getExpressionType in interface Expression

createSqlSelection

public SqlSelection createSqlSelection(int jdbcPosition,
 int valuesArrayPosition,
 JavaType javaType,
 boolean virtual,
 TypeConfiguration typeConfiguration)

Description copied from interface: SqlSelectionProducer

Create a SqlSelection for the given JDBC ResultSet position

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

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>

renderToSql

public void renderToSql(SqlAppender sqlAppender,
 SqlAstTranslator<?> walker,
 SessionFactoryImplementor sessionFactory)

Specified by:

renderToSql in interface SelfRenderingExpression

getJdbcMapping

public JdbcMapping getJdbcMapping()

Description copied from interface: SqlExpressible

Anything that is expressible at the SQL AST level would be of basic type.

Specified by:

getJdbcMapping in interface SqlExpressible

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>

forEachJdbcType

public int forEachJdbcType(int offset,
 IndexedConsumer<JdbcMapping> action)

Description copied from interface: JdbcMappingContainer

Visit each JdbcMapping starting from the given offset

Specified by:

forEachJdbcType in interface JdbcMappingContainer
