Method Details
-
clearInferred
Description copied from interface:InferencerConnectionRemoves all inferred statements from the specified/all contexts. If no contexts are specified the method operates on the entire repository.- Specified by:
clearInferredin interfaceInferencerConnection- Overrides:
clearInferredin classInferencerConnectionWrapper- 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.
-
commit
Description copied from class:InferencerConnectionWrapperCallsInferencerConnectionWrapper.flushUpdates()before forwarding the call to the wrapped connection.- Specified by:
commitin interfaceSailConnection- Overrides:
commitin classInferencerConnectionWrapper- Throws:
UnknownSailTransactionStateException- If the transaction state can not be determined (this can happen for instance when communication between client and server fails or times-out). It does not indicate a problem with the integrity of the store.SailException- If the SailConnection could not be committed.
-
addInferredStatement
public boolean addInferredStatement(Resource subj, IRI pred, Value obj, Resource... contexts) throws SailException Description copied from interface:InferencerConnectionAdds an inferred statement to a specific context.- Specified by:
addInferredStatementin interfaceInferencerConnection- Overrides:
addInferredStatementin classInferencerConnectionWrapper- 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:
SailException- If the statement could not be added.
-
addStatement
public void addStatement(Resource subject, IRI predicate, Value object, Resource... contexts) throws SailException Description copied from interface:SailConnectionAdds a statement to the store.- Specified by:
addStatementin interfaceSailConnection- Overrides:
addStatementin classSailConnectionWrapper- Parameters:
subject- The subject of the statement to add.predicate- The predicate of the statement to add.object- 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.
-
rollback
Description copied from interface:SailConnectionRolls back the transaction, discarding any uncommitted changes that have been made in this SailConnection.- Specified by:
rollbackin interfaceSailConnection- Overrides:
rollbackin classSailConnectionWrapper- Throws:
UnknownSailTransactionStateException- If the transaction state can not be determined (this can happen for instance when communication between client and server fails or times-out). It does not indicate a problem with the integrity of the store.SailException- If the SailConnection could not be rolled back.
-
begin
Description copied from interface:SailConnectionBegins a transaction requiringSailConnection.commit()orSailConnection.rollback()to be called to close the transaction. The transaction will use the defaultIsolationLevellevel for the SAIL, as returned bySail.getDefaultIsolationLevel().- Specified by:
beginin interfaceSailConnection- Overrides:
beginin classSailConnectionWrapper- Throws:
SailException- If the connection could not start a transaction or if a transaction is already active on this connection.
-
begin
Description copied from interface:SailConnectionBegins a transaction with the specifiedIsolationLevellevel, requiringSailConnection.commit()orSailConnection.rollback()to be called to close the transaction.- Specified by:
beginin interfaceSailConnection- Overrides:
beginin classSailConnectionWrapper- Parameters:
level- the transaction isolation level on which this transaction operates.- Throws:
UnknownSailTransactionStateException- If the IsolationLevel is not supported by this implementationSailException- If the connection could not start a transaction, if the supplied transaction isolation level is not supported, or if a transaction is already active on this connection.
-
flushUpdates
Description copied from interface:InferencerConnectionFlushes any pending updates to be processed and the resulting changes to be reported to registeredSailConnectionListeners.- Specified by:
flushUpdatesin interfaceInferencerConnection- Overrides:
flushUpdatesin classInferencerConnectionWrapper- Throws:
SailException- If the updates could not be processed.
-
statementAdded
Description copied from interface:SailConnectionListenerNotifies the listener that a statement has been added in a transaction that it has registered itself with.- Specified by:
statementAddedin interfaceSailConnectionListener- Parameters:
st- The statement that was added.
-
statementRemoved
Description copied from interface:SailConnectionListenerNotifies the listener that a statement has been removed in a transaction that it has registered itself with.- Specified by:
statementRemovedin interfaceSailConnectionListener- Parameters:
st- The statement that was removed.
-
addStatement
public void addStatement(UpdateContext modify, Resource subj, IRI pred, Value obj, Resource... contexts) throws SailException Description copied from interface:SailConnectionAdds a statement to the store. Called when adding statements through aUpdateExproperation.- Specified by:
addStatementin interfaceSailConnection- Overrides:
addStatementin classSailConnectionWrapper- Parameters:
modify- operation properties of theUpdateExproperation 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.
