Examples of org.apache.lucene.util.NamedThreadFactory

org.apache.lucene.util.NamedThreadFactory
A default {@link ThreadFactory} implementation that accepts the name prefixof the created threads as a constructor argument. Otherwise, this factory yields the same semantics as the thread factory returned by {@link Executors#defaultThreadFactory()}.
