## Class RepositoryWriteStrategy

- java.lang.Object
- - org.eclipse.rdf4j.federated.write.RepositoryWriteStrategy

- All Implemented Interfaces:
    AutoCloseable, WriteStrategy

      public class RepositoryWriteStrategy
      extends Object
      implements WriteStrategy

  A `WriteStrategy` to write to a designated `Repository`. This write strategy opens a fresh `RepositoryConnection` and keeps this until a call of `close()`.

  Note: this is an experimental feature which is subject to change in a future version.
