Class IndexWriterDelegate

java.lang.Object

org.hibernate.search.backend.impl.lucene.IndexWriterDelegate

public final class IndexWriterDelegate
extends Object

Encapsulates various operations to be performed on a single IndexWriter. Avoid using Workspace.getIndexWriter() directly as it bypasses lifecycle management of the IndexWriter such as reference counting, potentially leading to leaks.
