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()}.

  private final int[] starts;


  /** Creates a {@link Searchable} which searches <i>searchables</i> with the default 
   * executor service (a cached thread pool). */
