Constructor Detail

HanaExecutionFactory

public HanaExecutionFactory()

Method Detail

start

public void start()
           throws TranslatorException

Overrides:

start in class JDBCExecutionFactory

Throws:

TranslatorException

getHibernateDialectClassName

public String getHibernateDialectClassName()

Overrides:

getHibernateDialectClassName in class JDBCExecutionFactory

getSupportedFunctions

public List<String> getSupportedFunctions()

Overrides:

getSupportedFunctions in class JDBCExecutionFactory

supportsCompareCriteriaEquals

public boolean supportsCompareCriteriaEquals()

Overrides:

supportsCompareCriteriaEquals in class JDBCExecutionFactory

supportsInCriteria

public boolean supportsInCriteria()

Overrides:

supportsInCriteria in class JDBCExecutionFactory

translateLimit

public List<?> translateLimit(Limit limit,
                              ExecutionContext context)

Description copied from class: JDBCExecutionFactory

Return a List of translated parts (LanguageObjects and Objects), or null if to rely on the default translation.

Overrides:

translateLimit in class JDBCExecutionFactory

Returns:

a list of translated parts

getMetadata

public void getMetadata(MetadataFactory metadataFactory,
                        Connection connection)
                 throws TranslatorException

Overrides:

TranslatorException

getMetadataProcessor

public MetadataProcessor<Connection> getMetadataProcessor()

Overrides:

getMetadataProcessor in class JDBCExecutionFactory

supportsOnlyLiteralComparison

public boolean supportsOnlyLiteralComparison()

Overrides:

supportsOnlyLiteralComparison in class ExecutionFactory<DataSource,Connection>

getSQLConversionVisitor

public SQLConversionVisitor getSQLConversionVisitor()

Description copied from class: JDBCExecutionFactory

Create the SQLConversionVisitor that will perform translation. Typical custom JDBC connectors will not need to create custom conversion visitors, rather implementors should override existing JDBCExecutionFactory methods.

Overrides:

getSQLConversionVisitor in class JDBCExecutionFactory

Returns:

the SQLConversionVisitor

translate

public List<?> translate(LanguageObject obj,
                         ExecutionContext context)

Hana doesn't provide min/max(boolean)

Overrides:

translate in class JDBCExecutionFactory

Returns:

list of translated parts

translateLiteralBoolean

public String translateLiteralBoolean(Boolean booleanValue)

Description copied from class: JDBCExecutionFactory

Subclasses should override this method to provide a different sql translation of the literal boolean value. By default, a boolean literal is represented as: '0' or '1'.

Overrides:

translateLiteralBoolean in class JDBCExecutionFactory

Parameters:

booleanValue - Boolean value, never null

Returns:

Translated string
