DerbyAdapter

public DerbyAdapter()

Method Detail

createPkGenerator

protected PkGenerator createPkGenerator()

Description copied from class: JdbcAdapter

Creates and returns a primary key generator. This factory method should be overriden by JdbcAdapter subclasses to provide custom implementations of PKGenerator.

Overrides:

createPkGenerator in class JdbcAdapter

configureExtendedTypes

protected void configureExtendedTypes(ExtendedTypeMap map)

Installs appropriate ExtendedTypes as converters for passing values between JDBC and Java layers.

Overrides:

configureExtendedTypes in class JdbcAdapter

createTableAppendColumn

protected void createTableAppendColumn(java.lang.StringBuffer sqlBuffer,
                                       DbAttribute column)

Appends SQL for column creation to CREATE TABLE buffer. Only change for Derby is that " NULL" is not supported.

Overrides:

createTableAppendColumn in class JdbcAdapter

Since:

1.2

getQualifierTranslator

public QualifierTranslator getQualifierTranslator(QueryAssembler queryAssembler)

Returns a trimming translator.

Specified by:

getQualifierTranslator in interface DbAdapter

Overrides:

getQualifierTranslator in class JdbcAdapter
