addInferredStatement

public boolean addInferredStatement(Resource subj,
 IRI pred,
 Value obj,
 Resource... contexts)
                             throws SailException

Description copied from interface: InferencerConnection

Adds an inferred statement to a specific context.

Specified by:

addInferredStatement in interface InferencerConnection

Overrides:

addInferredStatement in class InferencerConnectionWrapper

Parameters:

subj - The subject of the statement to add.

pred - The predicate of the statement to add.

obj - The object of the statement to add.

contexts - The context(s) to add the statement to. Note that this parameter is a vararg and as such is optional. If no contexts are supplied the method operates on the entire repository.

Throws:

SailException - If the statement could not be added.

removeInferredStatement

public boolean removeInferredStatement(Resource subj,
 IRI pred,
 Value obj,
 Resource... contexts)
                                throws SailException

Description copied from interface: InferencerConnection

Removes an inferred statement from a specific context.

Specified by:

removeInferredStatement in interface InferencerConnection

Overrides:

removeInferredStatement in class InferencerConnectionWrapper

Parameters:

subj - The subject of the statement that should be removed.

pred - The predicate of the statement that should be removed.

obj - The object of the statement that should be removed.

contexts - The context(s) from which to remove the statements. Note that this parameter is a vararg and as such is optional. If no contexts are supplied the method operates on the entire repository.

Throws:

SailException - If the statement could not be removed.

clearInferred

public void clearInferred(Resource... contexts)
                   throws SailException

Description copied from interface: InferencerConnection

Removes all inferred statements from the specified/all contexts. If no contexts are specified the method operates on the entire repository.

Specified by:

clearInferred in interface InferencerConnection

Overrides:

clearInferred in class InferencerConnectionWrapper

Parameters:

contexts - The context(s) from which to remove the statements. Note that this parameter is a vararg and as such is optional. If no contexts are supplied the method operates on the entire repository.

Throws:

SailException - If the statements could not be removed.

commit

public void commit()
            throws SailException

Description copied from class: InferencerConnectionWrapper

Calls InferencerConnectionWrapper.flushUpdates() before forwarding the call to the wrapped connection.

Specified by:

commit in interface SailConnection

Overrides:

commit in class InferencerConnectionWrapper

Throws:

UnknownSailTransactionStateException - If the transaction state can not be determined (this can happen for instance when communication between client and server fails or times-out). It does not indicate a problem with the integrity of the store.

SailException - If the SailConnection could not be committed.

rollback

public void rollback()
              throws SailException

Description copied from interface: SailConnection

Rolls back the transaction, discarding any uncommitted changes that have been made in this SailConnection.

Specified by:

Overrides:

rollback in class SailConnectionWrapper

Throws:

UnknownSailTransactionStateException - If the transaction state can not be determined (this can happen for instance when communication between client and server fails or times-out). It does not indicate a problem with the integrity of the store.
