    • close

      public void close() throws SailException
      Description copied from interface: SailClosable
      Closes this resource, relinquishing any underlying resources.
      Specified by:
      close in interface AutoCloseable
      Specified by:
      close in interface SailClosable
      Throws:
      SailException - if this resource cannot be closed

    • prepare

      public void prepare() throws SailException
      Description copied from interface: SailSink
      Checks if this SailSink is consistent with the isolation level it was created with. If this Sink was created with a IsolationLevels.SERIALIZABLE and another conflicting SailSink has already been SailSink.flush()ed, this method will throw a SailConflictException.
      Specified by:
      prepare in interface SailSink
      Throws:
      SailException

    • addRefback

      Parameters:
      prefix - The new prefix, or an empty string in case of the default namespace.

    • removeNamespace

      public void removeNamespace(String prefix)
      Description copied from interface: SailSink
      Removes a namespace declaration by removing the association between a prefix and a namespace name.
      Specified by:
      removeNamespace in interface SailSink
      Parameters:
      prefix - The namespace prefix, or an empty string in case of the default namespace.

    • clearNamespaces

      public void clearNamespaces()
      Description copied from interface: SailSink
      Removes all namespace declarations from this SailSource.
      Specified by:
      clearNamespaces in interface SailSink

    • observe

      public void observe(Resource subj, IRI pred, Value obj, Resource... contexts) throws SailConflictException
      Description copied from interface: SailSink
      Called to indicate matching statements have been observed and must not change their state until after this SailSink is committed, iff this was opened in an isolation level compatible with IsolationLevels.SERIALIZABLE.
      Specified by:
      observe in interface SailSink
      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: SailSink
      Called to indicate matching statements have been observed and must not change their state until after this SailSink is committed, iff this was opened in an isolation level compatible with IsolationLevels.SERIALIZABLE.
      Specified by:
      observe in interface SailSink
      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.

    • observeAll

      public void observeAll(Set<Changeset.SimpleStatementPattern> observed)
      Specified by:
      observeAll in interface SailSink

    • clear

      public void clear(Resource... contexts)
      Description copied from interface: SailSink
      Removes all statements from the specified/all contexts. If no contexts are specified the method operates on the entire repository.
      Specified by:
      clear in interface SailSink
      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.

      public void approve(Statement statement)
      Description copied from interface: SailSink
      Adds a statement to the store.
      Specified by:

      statement - The statement to add.

    • approve

      public void approve(Resource subj, IRI pred, Value obj, Resource ctx) throws SailException
      Description copied from interface: SailSink
      Adds a statement to the store.

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

    • deprecate

      public void deprecate(Statement statement)
      Description copied from interface: SailSink

    • shallowClone

      public Changeset 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.
