org.modeshape.jcr.spi.federation.Connector
SPI of a generic external connector, representing the interface to an external system integrated with ModeShape. Since it is expected that the documents are well formed (structure-wise), the {@link FederatedDocumentWriter} class should be used. This isthe base class for {@link WritableConnector} and {@link ReadOnlyConnector} which is what connector implementations are expectedto implement. @author Horia Chiorean (hchiorea@redhat.com)
