Method Details
-
close
Description copied from interface:SailClosableCloses this resource, relinquishing any underlying resources.- Specified by:
closein interfaceAutoCloseable- Specified by:
closein interfaceSailClosable- Throws:
SailException- if this resource cannot be closed
-
prepare
Description copied from interface:SailSinkChecks if thisSailSinkis consistent with the isolation level it was created with. If this Sink was created with aIsolationLevels.SERIALIZABLEand another conflictingSailSinkhas already beenSailSink.flush()ed, this method will throw aSailConflictException.- Specified by:
preparein interfaceSailSink- Throws:
SailException

hasDeprecated

addRefback
public void addRefback(org.eclipse.rdf4j.sail.base.SailDatasetImpl dataset) -
removeRefback
public void removeRefback(org.eclipse.rdf4j.sail.base.SailDatasetImpl dataset) -
isRefback
public boolean isRefback() -
prepend
-
setNamespace
Description copied from interface:SailSinkSets the prefix for a namespace.- Specified by:
setNamespacein interfaceSailSink- Parameters:
prefix- The new prefix, or an empty string in case of the default namespace.name- The namespace name that the prefix maps to.
-
removeNamespace
Description copied from interface:SailSinkRemoves a namespace declaration by removing the association between a prefix and a namespace name.- Specified by:
removeNamespacein interfaceSailSink- Parameters:
prefix- The namespace prefix, or an empty string in case of the default namespace.
-
clearNamespaces
public void clearNamespaces()Description copied from interface:SailSinkRemoves all namespace declarations from thisSailSource.- Specified by:
clearNamespacesin interfaceSailSink
-
observe
public void observe(Resource subj, IRI pred, Value obj, Resource... contexts) throws SailConflictException Description copied from interface:SailSinkCalled to indicate matching statements have been observed and must not change their state until after thisSailSinkis committed, iff this was opened in an isolation level compatible withIsolationLevels.SERIALIZABLE.- Specified by:
observein interfaceSailSink- Parameters:
subj- A Resource specifying the subject, or null for a wildcard.pred- A IRI specifying the predicate, or null for a wildcard.obj- A Value specifying the object, or null for a wildcard.contexts- The context(s) of the observed statements. Note that this parameter is a vararg and as such is optional. If no contexts are supplied the method operates on all contexts.- Throws:
SailConflictException
-
observe
public void observe(Resource subj, IRI pred, Value obj, Resource context) throws SailConflictException Description copied from interface:SailSinkCalled to indicate matching statements have been observed and must not change their state until after thisSailSinkis committed, iff this was opened in an isolation level compatible withIsolationLevels.SERIALIZABLE.- Specified by:
observein interfaceSailSink- Parameters:
subj- A Resource specifying the subject, or null for a wildcard.pred- A IRI specifying the predicate, or null for a wildcard.obj- A Value specifying the object, or null for a wildcard.context- The context of the observed statements.- Throws:
SailConflictException
-
observeAll
- Specified by:
observeAllin interfaceSailSink
-
clear
Description copied from interface:SailSinkRemoves all statements from the specified/all contexts. If no contexts are specified the method operates on the entire repository.- Specified by:
clearin interfaceSailSink- 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.
-
approve
Description copied from interface:SailSinkAdds a statement to the store. -
approve
Description copied from interface:SailSinkAdds a statement to the store.- Specified by:
approvein interfaceSailSink- 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.ctx- The context to add the statement to.- Throws:
SailException- If the statement could not be added, for example because no transaction is active.
-
deprecate
Description copied from interface:SailSinkRemoves a statement. -
toString
-
setChangeset
-
shallowClone
Create a shallow clone of this Changeset. The shallow clone does not clone the underlying data structures, this means that any changes made to the original will potentially be reflected in the clone and vice versa.- Returns:
- a new Changeset that is a shallow clone of the current Changeset.
