Method Detail

getJdbcValueExtractor

public ValueExtractor getJdbcValueExtractor()

Description copied from interface: SqlSelection

Get the extractor that can be used to extract JDBC values for this selection

Specified by:

getJdbcValueExtractor in interface SqlSelection

createSqlSelection

public SqlSelection createSqlSelection(int jdbcPosition,
                                       int valuesArrayPosition,
                                       JavaType javaType,
                                       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

typeConfiguration - The associated TypeConfiguration

resolve

public SqlSelection resolve(JdbcValuesMetadata jdbcResultsMetadata,
                            SessionFactoryImplementor sessionFactory)

Specified by:

resolve in interface SqlSelection

getValuesArrayPosition

public int getValuesArrayPosition()

Description copied from interface: SqlSelection

Get the position within the "JDBC values" array (0-based). Negative indicates this is not a "real" selection

Specified by:

getValuesArrayPosition in interface SqlSelection

getExpression

public Expression getExpression()

Description copied from interface: SqlSelection

The underlying expression.

Specified by:

getExpression in interface SqlSelection

getExpressionType

public MappingModelExpressible getExpressionType()

Description copied from interface: SqlSelection

Get the type of the expression

Specified by:

getExpressionType in interface Expression

Specified by:

getExpressionType in interface SqlSelection

isVirtual

public boolean isVirtual()

Description copied from interface: SqlSelection

Whether this is a virtual or a real selection item. Virtual selection items are not rendered into the SQL select clause.

Specified by:

isVirtual in interface SqlSelection

accept

public void accept(SqlAstWalker sqlAstWalker)

Specified by:

accept in interface SqlAstNode

Specified by:

accept in interface SqlSelection

getSqlExpression

public Expression getSqlExpression()

Specified by:

getSqlExpression in interface SqlExpressionAccess
