Method Detail

addInferredStatement

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

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.

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:

StoreException - If the statement could not be added.

removeInferredStatements

boolean removeInferredStatements(Resource subj,
                                 URI pred,
                                 Value obj,
                                 Resource... contexts)
                                 throws StoreException

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.

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:

StoreException - If the statement could not be removed.

flushUpdates

void flushUpdates()
                  throws StoreException

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