boolean includeInferred,
Resource... contexts)
Determines if the store contains any statements from the specified contexts that have a specific subject,
predicate and/or object.

|
void |
statementAdded(Statement statement)
Notifies the listener that a statement has been added in a transaction that it has registered itself with.
|
void |
statementRemoved(Statement statement)
Notifies the listener that a statement has been removed in a transaction that it has registered itself with.

multiple times within the same transaction by the same thread. If this method returns normally, the caller can
reasonably expect that a subsequent call to SailConnection.commit() will also return normally. If this method returns
