Class TransactionalSelectionVisitor

java.lang.Object
  org.hibernate.search.backend.impl.TransactionalSelectionVisitor

All Implemented Interfaces:

WorkVisitor<ContextAwareSelectionDelegate>

public class TransactionalSelectionVisitor
extends Object
implements WorkVisitor<ContextAwareSelectionDelegate>

This visitor applies the selection logic from the plugged IndexShardingStrategies to transactional operations, so similar to StreamingSelectionVisitor but preparing a context bound list of operations instead of sending all changes directly to the backend.
