Method Detail

getFactoryName

public String getFactoryName()

Description copied from interface: PersistenceFactory

Returns the name of this factory. A descriptive name that indicates the type of supported database server or SQL syntax.

Specified by:

getFactoryName in interface PersistenceFactory

Overrides:

getFactoryName in class GenericFactory

Returns:

The name of this factory

getQueryExpression

public QueryExpression getQueryExpression()

Description copied from interface: PersistenceFactory

Returns a new empty query expression suitable for the underlying SQL engine. The implementation will construct SQL query statements in the preferred syntax.

Specified by:

getQueryExpression in interface PersistenceFactory

Overrides:

getQueryExpression in class GenericFactory

Returns:

New empty query expression

isKeyGeneratorSequenceSupported

public boolean isKeyGeneratorSequenceSupported(boolean returning,
                                               boolean trigger)

Description copied from class: GenericFactory

Does persistence factory support generation of new key at the time of new object creation with sequence key generator?

Specified by:

isKeyGeneratorSequenceSupported in interface PersistenceFactory

Overrides:

isKeyGeneratorSequenceSupported in class GenericFactory

Parameters:

returning - Return generated key value with insert statement?

trigger - Use a database trigger to generate key?

Returns:

true if persistence factory is able to generate key with sequence key generator, false otherwise.

isKeyGeneratorSequenceTypeSupported

public boolean isKeyGeneratorSequenceTypeSupported(int type)

Does Sequence key generator support generation of key for the given SQL type?

Specified by:

isKeyGeneratorSequenceTypeSupported in interface PersistenceFactory

Overrides:

isKeyGeneratorSequenceTypeSupported in class GenericFactory

Parameters:

type - SQL type to check for support by sequence key generator.

Returns:

true if persistence factory is able to generate key of given SQL type with sequence key generator, false otherwise.

getSequenceBeforeSelectString

public String getSequenceBeforeSelectString(String seqName,
                                            String tableName,
                                            int increment)

Description copied from class: GenericFactory

Returns the database specific SELECT query string for fetching identity before the next INSERT statement gets executed.

Specified by:

getSequenceBeforeSelectString in interface PersistenceFactory

Overrides:

getSequenceBeforeSelectString in class GenericFactory

Parameters:

seqName - Name of sequence.
