  - ### Method Detail

    - #### addInferredStatement

          public boolean addInferredStatement(Resource subj,
                                              IRI pred,
                                              Value obj,

                                       throws SailException

      Description copied from interface: `InferencerConnection`
      Adds an inferred statement to a specific context.
      Specified by:
        `addInferredStatement` in interface `InferencerConnection`
      Overrides:
        `addInferredStatement` in class `InferencerConnectionWrapper`
      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.

    - #### removeInferredStatement

          public boolean removeInferredStatement(Resource subj,
                                                 IRI pred,

                                          throws SailException

      Description copied from interface: `InferencerConnection`
      Removes an inferred statement from a specific context.
      Specified by:
        `removeInferredStatement` in interface `InferencerConnection`
      Overrides:
        `removeInferredStatement` in class `InferencerConnectionWrapper`
      Parameters:
        `subj` - The subject of the statement that should be removed.
        `pred` - The predicate of the statement that should be removed.
        `obj` - The object of the statement that should be removed.
        `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 statement could not be removed.

    - #### clearInferred

          public void clearInferred(Resource... contexts)

      Description copied from interface: `InferencerConnection`
      Removes all inferred statements from the specified/all contexts. If no contexts are specified the method operates on the entire repository.
      Specified by:
        `clearInferred` in interface `InferencerConnection`
      Overrides:
        `clearInferred` in class `InferencerConnectionWrapper`
      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.

      Calls `InferencerConnectionWrapper.flushUpdates()` before forwarding the call to the wrapped connection.
      Specified by:
        `commit` in interface `SailConnection`
      Overrides:
        `commit` in class `InferencerConnectionWrapper`
      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.

    - #### rollback
