public class ExitableDirectoryReader extends FilterDirectoryReader
ExitableDirectoryReader
wraps a real index DirectoryReader
and
allows for a QueryTimeout
implementation object to be checked periodically
to see if the thread should exit or not. If QueryTimeout.shouldExit()
returns true, an ExitableDirectoryReader.ExitingReaderException
is thrown.Modifier and Type | Class and Description |
