Interface ProductDerivation

public interface ProductDerivation

Hooks for deriving products with additional functionality. All implementations of this interface will have a chance to mutate a Configuration both before and after the user-specified configuration data is loaded. The order in which the derivations are evaluated is determined by the specificity of the derivation type.

Method Detail

getType

int getType()

Return the type of derivation.

beforeConfigurationConstruct

void beforeConfigurationConstruct(org.apache.openjpa.lib.conf.ConfigurationProvider cp)

Provides the instance with a callback to mutate the initial properties of the ConfigurationProvider. This is primarily to alter or add properties that determine what type of configuration is constructed, and therefore is typically used at runtime only.

beforeConfigurationLoad

void beforeConfigurationLoad(OpenJPAConfiguration conf)

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

afterSpecificationSet

void afterSpecificationSet(OpenJPAConfiguration conf)

Called after the specification has been set.
