JDBCPersistenceProductDerivation

public JDBCPersistenceProductDerivation()

Method Detail

putBrokerFactoryAliases

public void putBrokerFactoryAliases(Map<String,String> m)

Description copied from interface: OpenJPAProductDerivation

Load default alias options into the given map. Each entry maps an alias to a broker factory class name. Replace anything previously under the desired keys.

Specified by:

putBrokerFactoryAliases in interface OpenJPAProductDerivation

getType

public int getType()

Description copied from interface: ProductDerivation

Return the type of derivation.

Specified by:

getType in interface ProductDerivation

validate

public void validate()
              throws Exception

Description copied from interface: ProductDerivation

Ensure that this derivation is valid. This action might consist of loading classes for the product this derivation represents to be sure they exist. Throw any throwable to indicate an invalid derivation. Invalid derivations will not be used.

Specified by:

validate in interface ProductDerivation

Overrides:

validate in class AbstractProductDerivation

Throws:

Exception

beforeConfigurationLoad

public boolean beforeConfigurationLoad(Configuration c)

Description copied from interface: ProductDerivation

Provides the instance with the opportunity to mutate conf before the user configuration is applied.

Specified by:

beforeConfigurationLoad in interface ProductDerivation

Overrides:

beforeConfigurationLoad in class AbstractProductDerivation

Returns:

true if given Configuration has been mutated.

afterSpecificationSet

public boolean afterSpecificationSet(Configuration c)

Description copied from interface: ProductDerivation

Called after the specification has been set.

Specified by:

afterSpecificationSet in interface ProductDerivation

Overrides:

afterSpecificationSet in class AbstractProductDerivation

Returns:

true if given Configuration has been mutated.

getSupportedQueryHints

public Set<String> getSupportedQueryHints()

Description copied from interface: ProductDerivation

Return set of Query hint keys recognized by this receiver.

Specified by:

getSupportedQueryHints in interface ProductDerivation

Overrides:

getSupportedQueryHints in class AbstractProductDerivation
