Class TransactionalOperationExecutorSelector

java.lang.Object

org.hibernate.search.backend.impl.TransactionalOperationExecutorSelector

All Implemented Interfaces:

IndexWorkVisitor<Void,TransactionalOperationExecutor>

public class TransactionalOperationExecutorSelector
extends Object
implements IndexWorkVisitor<Void,TransactionalOperationExecutor>

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.

Implementation note: This IndexWorkVisitor implementation intentionally does not perform the actual logic within the individual visit methods themselves but rather returns a delegate class for that purpose. This is to avoid the need for the allocation of a parameter object with the required input data, instead a method with the required parameters is exposed on said delegate.
