setTransactionSettings
Description copied from interface:SailConnection
Pass any transaction-specific settings to the SailConnection. This method needs to be called before the transaction isstarted
.Sail implementations can override this method to receive the transaction settings (to inspect and/or pass them along to any wrapped sail objects). Remember to call
super.setTransactionSettings(settings)
if you override this method.- Specified by:
setTransactionSettings
in interfaceSailConnection
- Overrides:
setTransactionSettings
in classSailConnectionWrapper
- Parameters:
settings
- the transaction settings on which the next transaction operates. It may or may not contain the isolation level.
-
begin
Description copied from interface:SailConnection
Begins a transaction requiringSailConnection.commit()
orSailConnection.rollback()
to be called to close the transaction. The transaction will use the defaultIsolationLevel
level for the SAIL, as returned bySail.getDefaultIsolationLevel()
.- Specified by:
begin
in interfaceSailConnection
- Overrides:
begin
in classSailConnectionWrapper
- Throws:
SailException
- If the connection could not start a transaction or if a transaction is already active on this connection.
-

begin
in classSailConnectionWrapper
- Parameters:
level
- the transaction isolation level on which this transaction operates.- Throws:

operation producing these statements.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 specified, a context-less statement will be added.- Throws:
SailException
- If the statement could not be added, for example because no transaction is active.
-
removeStatement
public void removeStatement(UpdateContext modify, Resource subj, IRI pred, Value obj, Resource... contexts) throws SailException Description copied from interface:SailConnection

- If the statement could not be removed, for example because no transaction is active.
-

SailException
- If the statement could not be added, for example because no transaction is active.
-
removeStatements
public void removeStatements(Resource subj, IRI pred, Value obj, Resource... contexts) throws SailException Description copied from interface:SailConnection
Removes all statements matching the specified subject, predicate and object from the repository. All three parameters may be null to indicate wildcards.- Specified by:

in classSailConnectionWrapper
- Parameters:
subj
- The subject of the statement that should be removed, or null to indicate a wildcard.pred
- The predicate of the statement that should be removed, or null to indicate a wildcard.obj
- The object of the statement that should be removed , or null to indicate a wildcard. *contexts
- The context(s) from which to remove the statement. Note that this parameter is a vararg and as such is optional. If no contexts are specified the method operates on the entire repository. A null value can be used to match context-less statements.- Throws:
SailException
- If the statement could not be removed, for example because no transaction is active.
-
clear
Description copied from interface:SailConnection
Removes all statements from the specified/all contexts. If no contexts are specified the method operates on the entire repository.- Specified by:
clear
in interfaceSailConnection
- Overrides:
clear
in classSailConnectionWrapper
- 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 specified the method operates on the entire repository. A null value can be used to match context-less statements.- Throws:
SailException

-
rollback
Description copied from interface:SailConnection
Rolls back the transaction, discarding any uncommitted changes that have been made in this SailConnection.- Specified by:
rollback
in interfaceSailConnection
- Overrides:
rollback
in classSailConnectionWrapper
- Throws:
SailException
- If the SailConnection could not be rolled back.
-
close
Description copied from interface:SailConnection
Closes the connection. Any updates that haven't been committed yet will be rolled back. The connection can no longer be used once it is closed.- Specified by:
close
in interfaceAutoCloseable
- Specified by:
close
in interfaceSailConnection
- Overrides:
close
in classSailConnectionWrapper
- Throws:
SailException
-
prepare
Description copied from interface:SailConnection
Checks for an error state in the active transaction that would force the transaction to be rolled back. This is an optional call; calling or not calling this method should have no effect on the outcome ofSailConnection.commit()
orSailConnection.rollback()
. A call to this method must be followed by (in the same thread) with a call toSailConnection.prepare()
,SailConnection.commit()
,SailConnection.rollback()
, orSailConnection.close()
. This method may be called multiple times within the same transaction by the same thread. If this method returns normally, the caller can reasonably expect that a subsequent call toSailConnection.commit()
will also return normally. If this method returns with an exception the caller should treat the exception as if it came from a call toSailConnection.commit()
.- Specified by:
prepare
in interfaceSailConnection
- Overrides:
prepare
in classSailConnectionWrapper
- Throws:
SailException
- If there is an active transaction and it cannot be committed.
-

in interfaceSailConnectionListener
- Parameters:
statement
- The statement that was added.
-
statementRemoved
Description copied from interface:SailConnectionListener
Notifies the listener that a statement has been removed in a transaction that it has registered itself with.- Specified by:

- The statements matching the specified pattern.

hasStatement
public boolean hasStatement(Resource subj, IRI pred, Value obj, boolean includeInferred, Resource... contexts) throws SailException Description copied from interface:SailConnection
Determines if the store contains any statements from the specified contexts that have a specific subject, predicate and/or object. All three parameters may be null to indicate wildcards.

subj
- A Resource specifying the subject, or null for a wildcard.pred
