Method Detail

addInferredStatement

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

Adds an inferred statement to a specific context.

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.

context - A resource identifying the named context to add the statement to, or null to add the statement to the null context.

Throws:

SailException - If the statement could not be added.

removeInferredStatement

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

Removes an inferred statement from a specific context.

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.

context - A resource identifying the named context to remove the statement from, or null to remove the statement from the null context.

Throws:

SailException - If the statement could not be removed.

clearInferred

void clearInferred(Resource... contexts)
                   throws SailException

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

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.

flushUpdates

void flushUpdates()
                  throws SailException

Flushes any pending updates to be processed and the resulting changes to be reported to registered SailConnectionListeners.

Throws:

SailException - If the updates could not be processed.
