Class EnumerationAdapter

java.lang.Object
  sf.qof.adapter.EnumerationAdapter

All Implemented Interfaces:

GeneratorMappingAdapter, MappingAdapter

public class EnumerationAdapter
extends Object
implements GeneratorMappingAdapter

EnumerationAdapter is a generator mapping adapter for Java enumerations.

It uses enum.name() to map an enumeration to a VARCHAR and enum.valueOf(String) to map it back.

Constructor Summary

EnumerationAdapter()

Method Summary

void	generateFromResult(ResultMapping resultMapping, net.sf.cglib.core.CodeEmitter co, net.sf.cglib.core.Local result, int[] indexes) Method to map the current record of a result set or the result of a callable statement to an object on the stack.
void	generateFromResultSet(ResultMapping resultMapping, net.sf.cglib.core.CodeEmitter co, net.sf.cglib.core.Local resultSet, String[] columns) Method to map the current record of a result set to an object on the stack.
void	generateRegisterOutputParameters(ResultMapping resultMapping, net.sf.cglib.core.CodeEmitter co, net.sf.cglib.core.Local callableStatement, int[] indexes) Method to register an output parameter in a callable statement.
void	generateToPreparedStatement(ParameterMapping parameterMapping, net.sf.cglib.core.CodeEmitter co, net.sf.cglib.core.Local preparedStatement, int[] indexes, net.sf.cglib.core.Local indexOffset) Method to map the object on top of the stack to a prepared statement.
int	getNumberOfColumns() Returns the number of mapped columns.
Set<Class<?>>	getTypes() Returns the set of mappable Java types.
static void	register() Register the mapping adapter with the default name "enum".
static void	register(String typeName) Register the mapping adapter with the specified name.

                               int[] indexes)

Description copied from interface: GeneratorMappingAdapter

Method to map the current record of a result set or the result of a callable statement to an object on the stack. indexes defines the SQL indexes for the result set to be used in functions such a getInt(index).

Specified by:

generateFromResult in interface GeneratorMappingAdapter

Parameters:

resultMapping - the result mapping

co - code emitter

result - ResultSet or CallableStatement local variable

indexes - array of SQL indexes

generateFromResultSet

public void generateFromResultSet(ResultMapping resultMapping,
                                  net.sf.cglib.core.CodeEmitter co,
                                  net.sf.cglib.core.Local resultSet,
                                  String[] columns)

Description copied from interface: GeneratorMappingAdapter

Method to map the current record of a result set to an object on the stack. columns defines the SQL column name for the result set to be used in functions such a getInt(name).

Specified by:

generateFromResultSet in interface GeneratorMappingAdapter

Parameters:

resultMapping - the result mapping

co - code emitter

resultSet - ResultSet local variable

columns - array of SQL column names

generateToPreparedStatement

public void generateToPreparedStatement(ParameterMapping parameterMapping,
                                        net.sf.cglib.core.CodeEmitter co,
                                        net.sf.cglib.core.Local preparedStatement,
                                        int[] indexes,
                                        net.sf.cglib.core.Local indexOffset)

Description copied from interface: GeneratorMappingAdapter

Method to map the object on top of the stack to a prepared statement. indexes defines the SQL index for the prepared statement to be used in functions such a setInt(index, value).

Specified by:

generateToPreparedStatement in interface GeneratorMappingAdapter

Parameters:

parameterMapping - the parameter mapping

co - code emitter

preparedStatement - prepared statement local variable

indexes - array of SQL indexes

indexOffset - offset to be added to the indexes if not null

generateRegisterOutputParameters
