destinations

Type Members

1. class CompositeDestination extends Destination

   

   A destination that is composed of different child destinations.

   A destination that is composed of different child destinations. Each statement is forwarded to all child destinations.

   This class does not use synchronization, but if the target datasets are thread-safe then so is this destination. The write() method may be executed concurrently by multiple threads.

2. class DatasetDestination extends Destination

   

   A destination which groups quads by dataset and writes them to different destinations.

   A destination which groups quads by dataset and writes them to different destinations.

   This class does not use synchronization, but if the target datasets are thread-safe then so is this destination. The write() method may be executed concurrently by multiple threads.

3. class DeduplicatingDestination extends WrapperDestination

   

4. trait Destination extends Serializable

   

   A destination for RDF quads.

5. class LimitingDestination extends WrapperDestination

   

   Passes quads through to the target destination until a maximum number of quads is reached.

   Passes quads through to the target destination until a maximum number of quads is reached. After that, additional quads are ignored.

   TODO: Maybe this should be a mixin trait?

6. class MarkerDestination extends WrapperDestination

   

   Handles a marker file that signals that the extraction is either running ('start mode') or finished ('end mode').

   Handles a marker file that signals that the extraction is either running ('start mode') or finished ('end mode').

   In 'start mode', the file is created before the extraction starts (it must not already exist) and deleted after the extraction ends.

   In 'end mode', the file is deleted before the extraction starts (if it already exists) and re-created after the extraction ends.

7. abstract class WrapperDestination extends Destination

   

   Base class for destinations that forward most calls to another destination.

8. class WriterDestination extends Destination

   

   Writes quads to a writer.
