Method Detail

getExpression

public Expression getExpression()

Description copied from interface: SqlSelection

The underlying expression.

Specified by:

getExpression in interface SqlSelection

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

getJdbcResultSetIndex

public int getJdbcResultSetIndex()

Description copied from interface: SqlSelection

Get the JDBC position (1-based)

Specified by:

getJdbcResultSetIndex 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

getExpressionType

public JdbcMappingContainer getExpressionType()

Description copied from interface: SqlSelection

Get the type of the expression

Specified by:

                            SessionFactoryImplementor sessionFactory)

Specified by:

resolve in interface SqlSelection

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()
