Constructor Details

DB2Adapter

public DB2Adapter(RuntimeProperties runtimeProperties,
 List<ExtendedType> defaultExtendedTypes,
 List<ExtendedType> userExtendedTypes,
 List<ExtendedTypeFactory> extendedTypeFactories,
 ResourceLocator resourceLocator,
 ValueObjectTypeRegistry valueObjectTypeRegistry)

Method Details

createPkGenerator

protected PkGenerator createPkGenerator()

Creates a DB2 specific PK Generator.

Overrides:

createPkGenerator in class JdbcAdapter

configureExtendedTypes

protected void configureExtendedTypes(ExtendedTypeMap map)

Description copied from class: JdbcAdapter

Called from JdbcAdapter.initExtendedTypes(List, List, List, ValueObjectTypeRegistry) to load adapter-specific types into the ExtendedTypeMap right after the default types are loaded, but before the DI overrides are. This method has specific implementations in JdbcAdapter subclasses.

Overrides:

configureExtendedTypes in class JdbcAdapter

createTableAppendColumn

public void createTableAppendColumn(StringBuffer sqlBuffer,
 DbAttribute column)

Description copied from class: JdbcAdapter

Appends SQL for column creation to CREATE TABLE buffer.

Specified by:

createTableAppendColumn in interface DbAdapter

Overrides:

createTableAppendColumn in class JdbcAdapter

Parameters:

sqlBuffer - the StringBuffer to append the column type to

column - the DbAttribute defining the column to append type for

Since:

4.0

typeSupportsLength

public boolean typeSupportsLength(int type)

Description copied from class: JdbcAdapter

Returns true if supplied type can have a length attribute as a part of column definition

Specified by:

typeSupportsLength in interface DbAdapter

Overrides:

typeSupportsLength in class JdbcAdapter

Since:

4.0

getSqlTreeProcessor

public SQLTreeProcessor getSqlTreeProcessor()

Specified by:

getSqlTreeProcessor in interface DbAdapter

Overrides:

getSqlTreeProcessor in class JdbcAdapter

Returns:

SQLTreeProcessor that can adjust SQL tree to specific database flavour

Since:

4.2

getEjbqlTranslatorFactory

public EJBQLTranslatorFactory getEjbqlTranslatorFactory()

Description copied from class: JdbcAdapter

Returns a translator factory for EJBQL to SQL translation. The factory is normally initialized in constructor by calling JdbcAdapter.createEJBQLTranslatorFactory(), and can be changed later by calling JdbcAdapter.setEjbqlTranslatorFactory(EJBQLTranslatorFactory).

Specified by:

getEjbqlTranslatorFactory in interface DbAdapter

Overrides:

getEjbqlTranslatorFactory in class JdbcAdapter

Since:

4.0

bindParameter

public void bindParameter(PreparedStatement statement,
 ParameterBinding binding)
                   throws Exception

Description copied from interface: DbAdapter

Binds an object value to PreparedStatement's parameter.

Specified by:

bindParameter in interface DbAdapter

Overrides:

bindParameter in class JdbcAdapter

Throws:

Exception

getAction

public SQLAction getAction(Query query,
 DataNode node)

Uses special action builder to create the right action.

Specified by:

getAction in interface DbAdapter

Overrides:

getAction in class JdbcAdapter

Since:

3.1
