Constructor Detail

SailSourceConnection

protected SailSourceConnection(AbstractSail sail,
                               SailStore store,
                               FederatedServiceResolver resolver)

Creates a new SailConnection, using the given SailStore to manage the state.

Parameters:

sail -

store -

resolver - the FederatedServiceResolver to use with the default EvaluationStrategy.

SailSourceConnection

protected SailSourceConnection(AbstractSail sail,
                               SailStore store,
                               EvaluationStrategyFactory evalStratFactory)

Creates a new SailConnection, using the given SailStore to manage the state.

Parameters:

sail -

store -

evalStratFactory - the EvaluationStrategyFactory to use.

Method Detail

getFederatedServiceResolver

public FederatedServiceResolver getFederatedServiceResolver()

Returns the FederatedServiceResolver being used.

Returns:

null if a custom EvaluationStrategyFactory is being used.

setFederatedServiceResolver

public void setFederatedServiceResolver(FederatedServiceResolver resolver)

Sets the FederatedServiceResolver to use. If a custom EvaluationStrategyFactory is being used then this only has an effect if it implements FederatedServiceResolverClient.

Specified by:

setFederatedServiceResolver in interface FederatedServiceResolverClient

getEvaluationStrategy

protected EvaluationStrategy getEvaluationStrategy(Dataset dataset,
