Modifier and Type	Method	Description
void	addStatement(Resource subj, IRI pred, Value obj, Resource... contexts)	Adds a statement to the store.
void	addStatement(UpdateContext modify, Resource subj, IRI pred, Value obj, Resource... contexts)	Adds a statement to the store.
void	begin()	Begins a transaction requiring SailConnection.commit() or SailConnection.rollback() to be called to close the transaction.
void	begin(IsolationLevel level)	Begins a transaction with the specified IsolationLevel level, requiring SailConnection.commit() or SailConnection.rollback() to be called to close the transaction.
void	clear(Resource... contexts)	Removes all statements from the specified/all contexts.
void	clearNamespaces()	Removes all namespace declarations from the repository.
void	close()	Closes the connection.
void	commit()	Commits any updates that have been performed since the last time SailConnection.commit() or SailConnection.rollback() was called.
void	endUpdate(UpdateContext modify)	Indicates that the given op will not be used in any call again.
CloseableIteration<? extends BindingSet>	evaluate(TupleExpr tupleExpr, Dataset dataset, BindingSet bindings, boolean includeInferred)	Evaluates the supplied TupleExpr on the data contained in this Sail object, using the (optional) dataset and supplied bindings as input parameters.
Explanation	explain(Explanation.Level level, TupleExpr tupleExpr, Dataset dataset, BindingSet bindings, boolean includeInferred, int timeoutSeconds)	Explain how the TupleExpr will be (or has been) executed/evaluated by returning a TupleExpr (which may or may not be the provided TupleExpr) that has gone through zero or more of the stages prior to and also including execution as specified by the provided level.
void	flush()	Flushes any pending updates and notify changes to listeners as appropriate.
Comparator<Value>	getComparator()	Different underlying datastructures may have different ways of ordering statements.
CloseableIteration<? extends Resource>	getContextIDs()	Returns the set of all unique context identifiers that are used to store statements.
FederatedServiceResolver	getFederatedServiceResolver()	Gets the FederatedServiceResolver used by this client.
String	getNamespace(String prefix)	Gets the namespace that is associated with the specified prefix, if any.
CloseableIteration<? extends Namespace>	getNamespaces()	Gets the namespaces relevant to the data contained in this Sail object.
CloseableIteration<? extends Statement>	getStatements(StatementOrder statementOrder, Resource subj, IRI pred, Value obj, boolean includeInferred, Resource... contexts)	Gets all statements from the specified contexts that have a specific subject, predicate and/or object.
CloseableIteration<? extends Statement>	getStatements(Resource subj, IRI pred, Value obj, boolean includeInferred, Resource... contexts)	Gets all statements from the specified contexts that have a specific subject, predicate and/or object.
Set<StatementOrder>	getSupportedOrders(Resource subj, IRI pred, Value obj, Resource... contexts)	The underlying store may support some, but not all, statement orders based on the statement pattern.
boolean	hasStatement(Resource subj, IRI pred, Value obj, boolean includeInferred, Resource... contexts)	Determines if the store contains any statements from the specified contexts that have a specific subject, predicate and/or object.
boolean	isActive()	Indicates if a transaction is currently active on the connection.
boolean	isOpen()	Checks whether this SailConnection is open.
void	prepare()	Checks for an error state in the active transaction that would force the transaction to be rolled back.
Optional<TupleExpr>	prepareQuery(QueryLanguage ql, Query.QueryType type, String query, String baseURI)	Allows the SailConnection to bypass the standard query parser and provide its own internal TupleExpr implementation.
void	removeNamespace(String prefix)	Removes a namespace declaration by removing the association between a prefix and a namespace name.
void	removeStatement(UpdateContext modify, Resource subj, IRI pred, Value obj, Resource... contexts)	Removes all statements matching the specified subject, predicate and object from the repository.
void	removeStatements(Resource subj, IRI pred, Value obj, Resource... contexts)	Removes all statements matching the specified subject, predicate and object from the repository.
